Art in the form of visual arts, music, theater and cinema has become one of the most popular topics in human societies in the present age. Hence, the influence of art and artistic events in political, geographical and social relations is worth considering. The historical course of the word "art" also shows that the word "art" evokes a common meaning and concept in different geographical places and spaces. Hence, it can have a proper and direct relationship with geography. Iran's political relations with African countries, including Tunisia and other North African countries, have a long history due to common cultural and artistic features. Attending art festivals and creating memorandums of understanding in the fields of art, culture and education show the deep relations between Iran and Tunisia. The present study investigates the presence of theater artists in the events and festivals of Tunisia and the influence of cultural and artistic relations on the political and social relations of the two countries using a descriptive-analytical method and using library resources. What is clear is that Iran and Tunisia, as two Muslim countries, have a lot in common, and holding artistic and cultural festivals due to the peacefulness of such events also contributes to the enrichment of the relations between the two countries in the political and social arenas, and the country of Tunisia, the security of political relations and provide Iran's economy in North Africa and this will improve Iran's political relations with other countries in this region

The Persian Gulf region is one of the strategic and important regions in the world which has always attracted the attention of regional and trans-regional powers. In the contemporary world, the Persian Gulf region and the countries of the Southwest Asia region have been among the most challenging and controversial regions in the world. This region has been the hotbed of geopolitical crises and the site of ideological conflicts and the active hotspot of political and regional crises. In addition to the domestic context, the presence and involvement of trans-regional and global powers in activating and intensifying these challenges and crises have played a very crucial role. Although the macro-structures of the global geopolitical system have overshadowed this space, the powers within the region (the Islamic Republic of Iran and Saudi Arabia) have played a leading role in shaping the geopolitical atmosphere of the current situation, which is based on ideological and geopolitical values. The current study seeks to examine the ideological and geopolitical implications of Iran and Saudi Arabia for the region and the need to adopt a geo-economic strategy to overcome intra-regional geopolitical challenges. The results show that the adoption of a geo-economic strategy by Iran and Saudi Arabia can pave the way for a dialogue of cooperation and convergence and pave the way for entering a new regional geopolitical system for regional development and regionalism.

The present study seeks to answer the following question: 'why Turkey and Iran have been failed to use the critical junctures of recent decades as a starting point for national development and shaping regional development?' To answer the research question, new institutionalism was used as a theoretical approach to understand regional development. Acemoglu and Robinson's theory of Critical Junctures was also used to explain the reasons for the failure or success of countries in achieving development. In terms of research method, the present study is a case-oriented historical comparative study. The unit of analysis of this research is the country and global, international, regional and national events and conditions are selected and analyzed in relation to it. According to the study, Iran and Turkey have experienced two critical junctures since the 1990s, one as a result of internal processes and national elections and the other as a transnational event such as the military occupation of Iraq or the Arab Spring. It seems that Iran and Turkey have chosen the path of national development in the first critical juncture, but in the second critical juncture, both countries have entered into internal and regional tensions and conflicts and the process of national development have been encountered with several obstacles. In addition, the two countries have not been able to move institutionally and sustainably toward economic convergence over the past two decades. This inability has prevented the emergence of a developed region in the Middle East. The Middle East identity -based conflicts, exacerbated by foreign interventions and confrontational politics, have shifted the region's environment to militarization and security, making the space conducive to economic growth and prosperity leaving the region in poor economic growth and prosperity.

Although European integration was aimed at expanding regional co-operation and greater integration between member states, but the Corona Virus has threatened its main objectives. The purpose of this inquiry is to analyze the potential consequences of the spread of the Corona Virus on European co-operation and European strategic co-operation to manage this crisis. The present study was based on the hypothesis that weaknesses and failure of the EU members in the face of Corona Virus has intensified unilateralism among members of the European Union. The author using descriptive- analytic method looks consequences of Corona Virus in European countries. The research findings indicated that the Corona Virus triggered cracking of the gap between the states of the north and south and the emergence of populist movements. Also, hopelessness and mistrust, unemployment and poverty have been increased among EU members. In response to the crisis, the European Union has begun to strengthen its governance by looking at the previous experience and with investments in the health sector as a way to enhance the swing, flexibility and stability of the member countries economy.

Pacts can assist member countries in achieving foreign policy objectives and securing national interests. These pacts have diverse and numerous functions, influenced by geopolitical indicators to varying degrees. Naturally, their impact extends across national, local, regional, and transregional levels. Therefore, this research focuses on examining and analyzing the geopolitical indicators used in power calculations. The functions of pacts can manifest in significant political, security, economic, commercial, cultural, and social dimensions, and they can be applied in regional pacts.
This analytical-descriptive study relies on library resources, documents, articles, and relevant websites for data collection. Additionally, a structured questionnaire was prepared to gather experts' opinions on the analysis of geopolitical indicators for membership in regional pacts. Finally, the collected data underwent analysis using SPSS software and relevant tests. The study also strives to weigh countries' membership in regional pacts based on political, security, economic, commercial, cultural, and social components, and the impact of geopolitical indicators at various levels on the countries' membership process to regional pacts.

Based on the early theories of the foreign direct investment (FDI), trade and FDI are substitutes while the new international trade theories emphasize the complementary relationship between trade and FDI. This introduces new aspects to model fundamental concepts such as increasing returns to scale, product differentiation, and technology differences among countries. This paper is an empirical study of the interaction between trade and FDI using data on inward FDI to the ECO and D8 countries. To end this, we use instrumental variable and generalized two-stage least squares (G2SLS) techniques for panel data models. The results show that there is a complementary relationship between trade and FDI. Moreover, GDP, exchange rate, population, inflation, and some convergences variables have significantly influence on trade and FDI.

One of the problems associated with adaptive FIR filters in the identification of systems with long impulse responses, is their excessive computational complexity. Recently a new kind of adaptive filters, based on three-level clipping of the input signal has been presented for reduction of their computational complexity. In this paper, a theoretical analysis of the steady-state misalignment of adaptive filter equipped with the LMS algorithm, based on three-level clipping, is presented and by using it the minimum mean square error is achieved. This analysis can be a basis in the design of the above mentioned filters with appropriate clipping levels and proper step-sizes for system identification applications.

Abstract This paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. The proposed algorithm is expanded by using multiobjective optimization schemes. The objectives to be optimized in this paper are determined so as to reduce the SINR fluctuations as well as maintaining the SINR to an acceptable level with minimizing an average transmitted power. The convergence properties of the proposed algorithm are studied theoretically and with numerical simulations. The results indicate that the algorithm converges more rapidly and has lower average transmitted power than other existing algorithms. The current study also suggests a practical version of the proposed algorithm and compares it to the existing totally distributed bang-bang power control (B-BPC) or fixed step power control (FSPC) and multiobjective totally distributed power control (MOTDPC) algorithms. Numerical results show that the proposed algorithm is potentially much more efficient in terms of convergence speed and average consumption power than the other two algorithms.

This paper examines the existence of β-Convergence between per-capita incomes of selected Islamic countries. For this purpose, data over the period 1965-2006 and a time series approach proposed by Vogelsang (1998) are applied. Robustness of the estimated parameters to the presence of unit roots and/or serial correlations in the residuals is the main advantage of this method. The results show that per-capita income of most countries is converging to the average per-capita income of the selected Islamic countries, which provide evidence of β-Convergence. Cameroon, Indonesia, Malaysia, Niger, Chad, and Togo are the countries that have shown some forms of divergence either before the break date or after that. The estimated break dates are clustered and mostly related to the energy shocks in 1974, 1979, and 1986.

The convergence hypothesis is a result of the neoclassical growth model. By definition, the concept of convergence is the faster growth of regions (economies) with lower per capita income compared to the regions (economies) with higher per capita income. This paper deals with convergence clubs among provinces of Iran during 2000-2009. For this purpose, the Panel unit root tests have been used to examine the convergence hypothesis after classifying the provinces with cross-sectional methods. The research results show that Iran’s provinces can be classified into two groups of provinces: (1) ones with low per capita income (18 provinces) and (2) ones with high per capita income (12 provinces). According to the panel unit root tests, the existence of absolute convergence (tendency to a certain standard) between two mentioned groups is confirmed. So, the convergence clubs hypothesis is verified among the Iran’s provinces.

Education’s pivotal role in shaping cultural and identity elements is evident in its influence on both individuals and elites. This study explores sapioemotionality, referring to the emotional responses experienced by junior high school students when encountering elites. Persian language textbooks are considered crucial for cultural awareness. This study examines the portrayal of elites in these textbooks. Sapioemotionality, encompassing positive and negative convergence and divergence at individual and social levels, focuses on emotions elicited by elites’ presence. A total of 917 junior high students from various disciplines and levels participated in the study, completing the Sapioemotionality Questionnaire. The findings indicate significant gender disparities, with girls exhibiting higher sapioemotionality and a specific fascination with female elites. Tenth-grade students exhibited higher levels of sapioemotionality, which varied depending on their field of study. Mathematics-physics students demonstrated lower levels of sapioemotionality compared to literature and humanities, and experimental sciences students. A qualitative analysis of Persian Language textbooks, suggesting a shortfall in addressing sapioemotionality, with 76% of students perceiving a lack of attention to elites. These necessities textbook revisions that align with students’ emotional responses and cultural values, ensuring a more engaging and culturally relevant educational experience.

1. Introduction
The Curriculum Development Council prioritizes integrating Iranian identity into language and Persian literature textbooks, viewing them as key tools for cultural communication and motivation. Improving these textbooks, particularly in terms of cultural and identity elements, is a top priority for educational authorities. Additionally, individuals’ attitudes toward elites and celebrities, integral to national identity, can be shaped through textbooks that highlight their achievements.
Acknowledging the significance of investigating attitudes towards elites, the concept of “sapioemotionality” assesses emotions at individual and societal levels. The challenge of identity formation during adolescence further highlights the significance of socialization in shaping attitudes, emphasizing the critical role of textbooks in this process.
This study aims to examine Persian textbooks in grades ten to twelve as an effective tool for introducing Iranian culture, across various disciplines of literature and humanities, experimental sciences, and mathematics-physics. Initially, students’ sapioemotionality levels are assessed to gain insights into their emotional responses to elites. Additionally, students’ satisfaction with the portrayal of elites is evaluated. This is then compared with their sapioemotionality levels to assess the alignment between textbook content and students’ emotional responses.

1.2. Research Questions

1. Is there a significant difference in sapioemotionality between individual and societal levels among junior high school students?
2. Is there a significant difference in sapioemotionality between female and male junior high school students at individual and societal levels?
3. Is there a significant difference in sapioemotionality among junior high school students enrolled in different academic disciplines?
4. Is there a significant difference in sapioemoionality among junior high school students pursuing different academic disciplines?

5-  How have elites and celebrities been portrayed in Persian textbooks (1) , (2), and (3) for junior high school?

2. Literature Review
2.1. Sapioemotionality
Sapioemotionality, introduced by Pishghadam et al. (2021), focuses on individuals’ attitudes toward elites in shaping societal culture and national identity. This constructivist concept explores emotional responses to elites, considering positive/negative convergence and positive/negative divergence at individual and societal levels.
Positive Convergence: High sapioemotionality at both levels indicates high societal value and appreciation for elites.
Negative Convergence: Low sapioemotionality at both levels implies societal indifference or negativity toward elites.
Positive Divergence: High individual, low societal sapioemotionality suggests personal inclination toward elites not shared by society.
Negative Divergence: Low individual, high societal sapioemotionality indicates societal encouragement despite individual disinterest.
These nuances provide insights into emotional responses to elites, especially in academic settings. The study aims to understand sapioemotionality convergence and divergence across different dimensions, illustrated in Figure 1 (Pishghadam et al., 2021).

Figure 1
Sapioemotionality Dimensions


The results of the study by Pishghadam et al. (2021) indicate a positive divergence trend in Iranian society, where individuals aspire to interact with elites amidst a lack of societal support. This imbalance has contributed to a decline in the value placed on knowledge and academic achievement in the academic environment. If this persists, despite efforts to foster elitism, the study suggests a decline in possible elitism among adolescents, as evidenced in educational textbooks, particularly Persian ones. The content analysis of these books is critical for introducing Iranian culture to students, emphasizing the focus of the present research.

3. Methodology
This research adopts a mixed-methods approach, combining a qualitative analysis of Persian textbooks for the second year of secondary education alongside a concurrent quantitative investigation of sapioemotionality among tenth to twelfth-grade students across various disciplines of literature and humanities, experimental sciences, and mathematics-physics.
3. 1. Participants
The study encompasses 917 students (627 females, 290 males) aged 15 to 19, distributed across tenth (n = 413), eleventh (n = 257), and twelfth grades (n = 247) in literature and humanities (n = 509), experimental sciences (n = 309), and mathematics-physics (n = 99). Participants responded to the Sapioemotionality Questionnaire.

3.2. Research Tools
The quantitative data were collected by Sapioemotionality Questionnaire, developed by Pishghadam et al. (2021), who established the validity and reliability of the scale (Cronbach's alpha 0.88). This 10-item questionnaire measures sapioemotionality at individual and social levels.
In the qualitative phase, student satisfaction with how elites are portrayed in Persian textbooks for junior high schools is assessed. These textbooks, across various disciplines, contribute to the national identity of being elite. The content of the textbooks is subjected to a qualitative analysis, involving a comparison of different chapters and lessons.

3.3. Data Collection Procedures
Quantitative data were collected online through the distribution of the Sapioemotionality Questionnaire to students nationwide. The data were analyzed in SPSS (Ver. 21) using a one-way ANOVA for statistical evaluation.

                                                                                   4. Results
The paired sample t-test revealed that among junior high school students, sapioemotionality at the individual level exceeded the social level (t(916) = 31.13, p = 0.00). An independent t-test showed that female students had higher sapioemotionality than males at the individual level (t(915) = 3.45, p = 0.001). In comparison, female students exhibited higher sapioemotionality than males at the social level (t (915) = 3.88, p = 0.00).
Regarding sapioemotionality across grades, a one-way ANOVA indicated a significant difference (F(2, 914) = 6.92,  p = 0.001). Pairwise comparisons revealed higher sapioemotionality in tenth-grade students (36.63), compared to eleventh-grade (35.55) and twelfth-grade students (35.07). No significant difference was found between eleventh and twelfth-grade students. One-way ANOVA showed significant differences among literature and humanities, experimental sciences, and mathematics-physics students (F(2, 914) = 6.92, p = 0.001). Pairwise comparisons revealed lower sapioemotionality in mathematics-physics students (34.21), compared to literature and humanities (35.87) and experimental sciences students (36.17). No significant difference was observed between students of literature and humanities and students of experimental sciences.
After analyzing the textbooks, it was found that attention to elites was limited. This prompted a qualitative question in the Sapioemotionality Questionnaire. In fact, 76% of students believed that there was little attention, 19% felt there was moderate attention, and only 5% believed there was significant attention. This lack of attention raised concerns given the potential impact on students’ behavioral and performance models during the identity crisis period.
Considering the emotional weight of language, it is crucial to align educational content with students’ interests. The research suggests tailoring attention to elites in textbooks based on gender characteristics and age to cultivate cultural values. The study emphasizes the need for future research on “emolings” related to elites in educational content, aiming for a more nuanced discourse and positive sapioemotionality.

Phet Tropical Storm is an emerging sign of climate change in the Indian Ocean and Arabian Sea regions. Intensity of this storms for the first time in days between June 1, 2010 within the Indian Ocean and Arabian Sea were calving, day 3 June 2010 to four degrees in level Super Cyclone is reached. This storm occurred during the process of its unpredictable day June 4, 2010 (against the Persian date 14 Khordad 1389) in Chabahar near the southern shores of Iran, in which the dangerous part of the half circle on the coast was Chabahar. The integration of seas with Oman, Arabian Sea and Red Sea moisture convergence region and the Gulf of Aden (the level of 850 hp at hours 9.30 in 4 June 2010) forms thunderstorm, severe convective storms and heavy rains on the coasts of Chabahar. The area was attacked by high sea waves and a heavy 109.5 mm rain, and brought along severe damages. Convergence of moisture flow can be regarded as the most important requirement of occurrence of rainfall from tropical storms being resulted from Phet Tropical stormy rainfall off the coast of Chabahar. The exception to the rule was wind mixture with precipitation and atmospheric moisture that created the convergence of moisture flow at different levels of atmosphere. Using the thermodynamic equations for the Moisture Flux Convergence (MFC) of atmospheric, along with route maps and related atmospheric moisture blowing winds on the western flow mapping, the analysis was carried out. Results of drawing and analysis of maps showed that the supply source and moisture injection to the Phet Tropical Cyclone moving towards the coast of Chabahar made losses except wind and moisture convergence during the balance of 850 hp 9.30 hours that injected moisture from the Gulf of Aden and Red Sea while the South West regional convergence took place. Other atmospheric levels on 4 June 2010 were through the resource injection and feeding of heavy rainfall and coastal moisture from Chabahar, Arabian Sea and Gulf of Oman. Also drawing maps of the location and position of convergent core moisture during storm in activity days showed that Phet in that date in most cases on or near the Chabahar coast were deployed as the core storage and moisture content aggregation with injection which have strengthened tropical Cyclone moisture into a heavy rain 109.5 mm.

Applying and combining h and p refinement techniques in isogeometric method with the possibility of continuity elevation that this method provides, convergence and error of using different kinds of shape functions with different orders and continuities is investigated. It is done in a numerical analysis framework of a practical and well known problem called “Diametral Compression Test”. The advantage of this case is its circular geometry, since IGA provides designers with high potency of the possibility of using minimum elements to make the exact circular geometry. The point load inserts singularity to the problem. The refinement is utilized uniformly as the effective parameters are limited to the kind, order and continuity of shape functions. With different refinement techniques the convergence of approximated solution to the exact solution of linear elasticity is examined. It is concluded that with the singularity that mentioned, the error in IGA is not necessarily reduced with raise in order, more precisely the level of continuity is another important issue to determine error raise. It is also seen that in the presence of point load singularity the rate of error converges to the same value for all degrees of NURBS and lagrangian shape functions with any continuity. At the beginning of refinement process the minimum number of elements is used to make the process clearer to understand. In next steps h and p techniques and their combination is used to refine the model.

Aerodynamic study of flows at low Reynolds for special applications such as micro unmanned underwater vehicles, underwater robots and explorers are interested. In this paper, an improved progressive preconditioning method named power-law preconditioning method, for analyzing unsteady laminar flows around hydrofoils is presented. In this method, the 2D Navier-Stokes equations modifies by altering the time derivative terms of the governing equations. The preconditioning matrix is adapted from the velocity flow-field by a power-law relation. The governing equation is integrated with a numerical resolution derived from the cell-centered Jameson’s finite volume algorithm and a dual-time implicit procedure is applied for solution of unsteady flows. The stabilization is achieved via the second- and fourth-order artificial dissipation scheme. Explicit four-step Runge–Kutta time integration is applied to achieve the steady-state condition. The computations are presented for unsteady laminar flows around NACA0012 hydrofoil at various angles of attack and Reynolds number. Results presented in the paper focus on the velocity profiles, lift and drag coefficient and effect of the power-law preconditioning method on convergence speed. The results show satisfactory agreement with numerical works of others and also indicate that using the power-law preconditioner improves the convergence rate and decreases the computational cost, significantly.

Banks as economic firms try to provide banking services in low cost. The efficiency of banking system and its convergence among the Iranian banks is a top priority for planners and decision-makers. In this research, the data of 9 Iranian banks (6 commercial and 3 specialized) during 2001-2012 period are utilized according to intermediate approach and Stochastic Frontier Analysis (SFA) within a translog cost function and Model I of Battese and Colli (1992). The results show that average efficiency for commercial and specialized banks has been 78.95% and 87.58%, respectively, which imply that the average efficiency of specialized banks is more than that of commercial banks. In addition, the convergence process has been studied as a result of economic growth models. The speed of efficiency convergence has been estimated by -571% in absolute   model, and -576% in conditional   model, respectively. The average efficiency growth is decreasing and the efficiency adjustment speed is convergent.

Societies and governments have considered tax as one of the most important ways of public financing. Moreover, identifying new tax capacity to improve tax status and to increase tax incomes is assumed substantial. On the other hand, most economists believe that economic status of a country is affected not only by the economic performance of region but also by the adjacent zones. Therefore, ignoring such spatial factors and linkages may negatively affect the performance of that region. Accordingly, convergence and the related subjects are increasingly drawing the attention of more economists. The present study tries to examine the tax capacity convergence among Iran's provinces during 2001-2011 using Spatial Econometrics in MATLAB software. The findings indicate that meaningful and negative coefficient of the lagged dependent variable represents the convergence of the tax to value added (VA) ratio to its long-term path.

Energy is one of the main production inputs, which indicates potential political and economic power in different countries. Due to higher energy prices, energy productivity is of special importance, and recent applied researches imply the effectiveness of energy productivity on economic growth. In addition, the process of regional economic growth is influenced by geographic conditions, regional and neighborhood specifications and functioning as well as usual regional economic variables including labor, capital, technology and energy. This paper estimates the effect of provincial energy productivity on provincial economic growth, using spatial econometric model and Maximum Likelihood method with applying provincial data from 2001 to 2011. In addition, it investigates β and σ convergence of energy productivity among Iran’s provinces. In spatial econometric method, we can consider the spillover effects and spatial relations among adjacent provinces with defining a distance-weight matrix between regions. Our findings indicate no σ convergence, but there is a conditional β convergence, which is a signal of existence of either spillover or neighborhood effect in provincial energy productivity growth. Meanwhile, the higher economic openness and lower government intervention in the economy improve energy productivity growth, but increasing energy price has no significant effect on the provincial energy productivity.

This paper aims to investigate convergence hypothesis in Iran provinces in terms of per capita income and per capita consumption over the period 2000- 2014 using the cluster analysis. In order to analyze this issue more exactly, in the first step, using taxonomy method, the provinces of the country are divided into three categories: underdeveloped provinces (5 provinces), developing provinces (13 provinces) and developed provinces (13 provinces). Then, the possibility of forming convergent clusters in terms of per capita income and per capita consumption is investigated in each group using cluster analysis. The results show that two convergent clusters (each cluster consists of only two provinces) are observed for per capita income among developed provinces. In studying the convergence status of the mentioned provinces, two clusters (each cluster with two provinces) are identified regarding per capita consumption. In the developing provinces, two clusters (one cluster with eight provinces and another one including two provinces) are formed in terms of per capita income, and two clusters are generated on the basis of per capita consumption(each cluster includes three provinces). In underdeveloped provinces, there is no convergent cluster. Therefore, in general, the findings indicate the divergence between per capita income and per capita consumption among all underdeveloped provinces and most of developed provinces, but there is some evidence of convergence in terms of per capita income among developing provinces in the long run.

This study presented the results of an experimental study on the dense flow discharging from convergent and inclined plane surface jet in stagnant and deep ambient resources. Development of industrial and commercial activities throughout the world leads to pollution of water resources. For example, The salt water obtaining from desalination process whose density exceeds the one of the ambient water is discharged into the sea by the desalination plants through discharging structures. Therefore, it is essential to study related processes to suitable transfer of effluent into the ambient. With respect to the importance of this matter, extensive studies have been conducted in recent years as physical and numerical modeling on examining and understanding of flow behavior discharging through submerged and surface jets. This study discusses the plunge and impact location under the effect of different variables. The study tests were carried out in a 3.2×0.6×0.9 m3 flume. The Jet fluid obtained from salt dissolution in water was prepared in three concentrations of 5, 15, and 45 g/lit. To show fluid’s moving path, the obtained solution was colored by using a substance with no effect on density changing. The flow rate of the jet fluid in values of 0.042, 0.08 and 0.105 lit/sec was adjusted by using an electromagnetic flow meter with the accuracy of 0.01 lit/sec. The injection of the jet fluid was carried out by using rectangular channels in four convergence angle of 12.5, 25, 45 and 90 degrees and the constant width of 0.06m. Width of the outlet section in all the channels were considered 0.035 m. Discharge channels injected the jet fluid tangent to the surface of the ambient water. Thus, the channels were installed and adjusted on a base at slopes of zero, 0.04 and 0.08 and certain convergence angle. The water depth in the flume was adjusted at a constant value of 0.7m in all experiments. The ambient fluid was settled before injection of the jet fluid. During this time interval, the temperature of the jet fluid and the ambient fluid were measured by a thermometer and their densities were measured by a hydrometer. For each experiment, the moving path of the jet fluid in the receiving ambient was recorded by using a Sony digital camcorder (DSC-WX220) with the frequency of 50 FPS. This camera recorded the images of flow’s section that was placed in front of the flume’s wall and perpendicular to the central vertical plane of the jet flow. The data was obtained by using of images routing process. Based on the results, the 8-percent slope has the longest length of plunge and impact locations. The 8-percent slope provides high initial momentum. Therefore, the flow has further advance in this condition. Slopes of 0 and 4 percent are very close to each other. Although the value of initial momentum exceeds zero in the 4-percent slope, the length of plunge and impact locations in the 4-percent slope are lower than zero slope. The initial momentum is divided into X and Z directions in 4 percent slope, but all initial momentum is in X direction in zero slope. While the longitudinal slope of the discharge channel is fixed, the length of plunge and impact locations reduce with the jet fluid concentration increasing. Density difference and buoyancy force increase with the concentration increasing. Flow becomes denser and it loses its contact with the surface more quickly. Besides that, the length of plunge and impact locations increases with the convergence angle decreasing. The initial momentum and the discharge velocity of jet flow increase with the convergence angle of discharge channel decreasing. Increasing the initial momentum leads to further advance of jet flow. As the ambient has a fixed depth, was seen the location of the plunge point in the range of 1.2 and the location of the impact point depending on the ambient depth. Finally, the ratio of the length of plunge to impact locations for data was within the range of 0.1-0.8.
