General circulation of Persian Gulf has a cyclonic pattern that affected by tide, wind stress and thermohaline force. Although tidal force is very effective in values of current speed, but thermohaline force is dominant in long time because tidal forcing has a short period and returning nature. Tide and density parameters are important in navigating and shipping, especially when ships approaching the shore and shallow water to determine the drainage of them. In this study using the Mike model based on the three-dimensional solution of the Navier Stokes equations, assumption of incompressibility, Boussinesq aproximation, and hydrostatic pressure, Persian Gulf circulation modelled. After model stability, the effects of tidal force on horizontal and vertical distribution of density were investigated. Results show that forcing of tide caused current direction be regular and without tidal force, wind stress dominates on isopycnal and turbulent pattern forms in sea surface layer especially in cool season. Also, with the elimination of the tide effect, the velocity of current is reduced to 75% and the water density is increased to 1-2 kg/m³. Density profile show that the Persian Gulf is a baroclinic environment and it is stronger in cool season relative to warm season. The impact of forces is not the same in different regions of the Persian Gulf, so that the effects on the change in density in the Strait of Hormuz are more perceptible and moving inward to the Gulf, the intensity of its effect is reduced.

This study aims at organizing the city of Poldokhtar in the city of Kashkan. Using this element of natural value, the city is being restored and organized, and its potential for tourism and development of tourism and economic prosperity is to be used. The paths of the rivers within the city can be used as a linear route, and can be used as a sustainable urban tourism axis. In the case of the spatial and spatial organization of the rivers for such a purpose, various, yet standardized patterns for shaping and managing the length of rivers can be used. Finally, the findings of library studies and the results of a field survey were distributed through a questionnaire and SPSS software using the Cronbach's alpha coefficient, the coefficient obtained in this study was equal to 8,377, which indicates the appropriate credit for Data collection. In the final stage, using the AMOS software and the structural equivalence method, the relationship between the main components of the research and the constituent variables has been analyzed and analyzed. The range of results showed that the most important strategy for creating urban river tourism in Poldokhtar is the attempt to create a social and secure environment with facilities and ease of access and special emphasis on environmental and ecological issues. For this reason, the main criteria for design based on local capabilities are defined. It should be noted that in the social, recreational, historical and environmental areas the same procedure is used, which means that all the spatial and spatial regulation strategies and parameters of the river in line with the native nature and the needs of the people living in the area and in A word of the users of the project has been used.

Cities are a place of accumulation of material and spiritual capital of humanity, which is of great importance. This type of settlement, with more than 50 percent of the world's population in it, has become more important in recent years and has been considered for the maintenance of principled and sustainable management of all types of planning. One of these plans has been the resilience of cities. Resilience to the threats and potential hazards that affect it when it occurs.   The concept of resilience has been proposed and discussed in various dimensions and levels. In this research, emphasis is placed on the physical dimensions of urban Resilience. The purpose of this study is to assess the resilience of the 1st district(zone) of Tabriz city against earthquake, which is analyzed using the Fuzzy AHP model. The 8 criteria, include the distance From relief centers, the distance from the centers of harm, the building materials, the quality of the building, the time of the building, the distance from the network of roads, the distance from the green and open spaces and the distance from the fault, is the base of analysis. After preparing the layer for each criteria, Fuzzy layers are extracted using fuzzy functions. Using the SUM, AND, GUMMA operators, the final layers were generated, which was evaluated using the Band Collection Statistics tool, the gamma layer 0.9 was selected as the best output. based on the scenario of gamma 0.9 in the study area, about 26% of the area has very low and low resilience. In contrast, more than 22% of the range is moderate and 51% of the area have a high resilience.

The purpose of this study is to determine the long-term variations in rainfall data as well as to identify wet and dry periods of 35 synoptic stations in Iran. In order to know the variation of rainfall in studied stations, average maps, coefficient of variation and skewness were drawn. Then, using the Mann-Kendall test, the significance of the trend on each station was tested at 95% confidence level. Finally, wet and dry periods were identified by using 20% high and low extreme rainfall during the 50-year study period. The results show that the general model of the country's regime is that the rainfall levels from the north to the south-east and from the west to the east of the country are reduced. The lowest values of the coefficient of variation and skewness are related to the northern regions especially the Caspian seaside and the highest amounts are in the southern regions, especially in the south and south-east. In general, the results of the Mann-Kendall test show that rainfall data in the seasonal scale, with the exception of several synoptic stations, do not show a significant trend. Most wet periods occur in the spring and the lowest in summer and the highest dry periods occur in the autumn and the lowest in spring. The number of droughts in the cold periods is significant. Also, the frequency of occurrence of dry periods is more than wet periods.

Human dignity is a concept that can have a significant impact on urban public space. In this sense, it speaks of the value of human beings and their status as a thoughtful and spiritual being. Discovering this valuable feeling in an environment that is widely used by citizens is important to the research. The subjective and interactive nature of this phenomenon The purpose of this study was to analyze explicit inductive qualitative content analysis as a research method and to interpret contextual data obtained from in-depth unstructured interviews and field observations, and its perception among various actors and how human dignity was generated. Used. The data were analyzed through a systematic coding process with the aim of classifying concepts up to three levels of abstraction. The selection of participants in this study was purposeful and aimed at developing concepts to reach saturation. The findings of this study indicate that the concept of socialization is one of the most important factors in people's perception of human dignity. It is conceptualized with other concepts such as loss of personal distance, development of social communication, intimacy, social diversity and unity with the environment and society. Is formed. What is of interest is the relationship between these factors and the complexity of their relationships that have led to the formation of a sense of human dignity in individuals. Although the multifaceted concept of human dignity will be able to accommodate the broad concepts and meanings that are involved in this study The concept of socialization of urban public space has been carefully considered.

In the meantime it can cause serious and irreparable damage to other social, economic and structural sectors of society. A look at the history of human life on Earth shows that human beings have always been exposed to all kinds of natural hazards. Natural hazards have many types, one of which is drought and water crisis. The recent droughts in Iran and the severity of the damage indicate the continued vulnerability of urban and rural areas. At present, drought management in our country is based on crisis management and thus less attention is paid to drought impacts and preparedness. Therefore, the purpose of this study is to evaluate the resilience of Zahedan city against water crisis and drought. The present study is applied in terms of purpose and in terms of research, descriptive and analytical. The statistical population of the study is all households in Zahedan city based on the census of 1395 168480 households (672589 people). From the household heads, a sample size of 383 people was selected randomly using Cochran formula. Descriptive statistics and inferential statistics were used to analyze the findings. The results of one-sample t-test show that the economic, social and institutional resiliency status in Zahedan city is lower than the average (2.815, 2.873 and 2.886, respectively); The results showed that Zahedan city is not in a good position in terms of resilience to drought and water crisis and this city has many water problems in rural areas and Zahedan city. Rural water shortages and droughts have caused extensive damage to farmers and ranchers. The effects of the water crisis on the economic, social and environmental structure of the villages have been very negative and these negative effects have ultimately led to the migration of villagers to Zahedan

In recent years, population growth and consequently the shortage of drinking water resources have increased the importance of studying the areas of caries Regarding the importance of the subject, in the present study, the evaluation and monitoring of the developed karstic areas and the potential of contamination of Cartesian resources in the Ravensar basin have been addressed In this study, 7factors were used to evaluate the factors of Karst development in Ravansar basin as well as two methods of OWA and ANP. The method of work is that after the necessary processing, using the OWA method and applying weights obtained through the ANP model, the zoning is done After designing the zoning map, using the satellite imagery of 2007 and2015, the development of human development areas in the developed karstic areas has been evaluated The results of this study indicate that most of the studied basin, especially in northern and western areas of the basin, are highly and relatively developed in the class, The calculation of the area of man-made areas suggests that in2007, about 2.6 km of occupied areas of man-made industrial zones have been occupied which, according to the growing population, increased to 3.8 km in2015, human-made areas have been extracted in developed artisanal areas

The innate sense of interaction with the region is a sign of environmental sensitivity, which is very vital in the 21st century. Today, it is inevitable that regionalism should be included in a larger discourse of architecture, and that the debate over the role of the use of regional green architecture as a factor in cultural identity and sense of place should be promoted. The present study argues that regionalist architecture has entered a new phase of its evolutionary process, which is sustainable regionalism. In this view, regions must be defined in terms of their unique resources and specific constraints. Instead of being influenced by globalization, regions must follow a complex interdependence in a global and regional interaction system that is physical, social, cultural, and most importantly ecological. Therefore, using the method of qualitative content analysis based on the logic of inductive reasoning, from the textual data and architectural experiences mentioned in the research, move and by extracting the hidden concepts in it, gradually reach more abstract levels of sustainable regionalism. We will find. In addition, using the latest works of architecture selected by international institutions and awards and competitions, we are developing examples of sustainable regionalism. Achieving a model or theoretical framework that demonstrates latent disciplines and repetitive patterns in regionalist architecture and sustainable architecture can be the culmination of research.
