This study investigates the subtropical anticyclones and summer monsoons of the north hemisphere in the 500 hPa level, effective on Iran in a 38-year period (1975-2012). For this purpose, the data of geopotential heights of 500 hPa at 12 UTC with a spatial resolution of 2 by 2 degrees of the (NCEP/NCAR) were used. Results show that three independent patterns (Azores anticyclone, Saudi anticyclone and North West Africa anticyclone) and four combinatory patterns derived from the independent patterns have controlled the atmosphere of 500 hPa level of Iran. In most cases, the maximum in geopotential heights in above-mentioned anticyclone centers reach to more than 5920 geopotential meters, but often the tongue of these anticyclones control the atmosphere of 500 hPa levels of Iran with the geopotential height of 5880 to 5900 meters. In contrast, at this pressure level, the large-scale monsoon system is very weak and the maximum geopotential height of this system is about 5840 meters. The extent and intensity of the monsoon system has been reduced so that its tongues do not affect the 500 hPa level of Iran at any time. Given that the main factor in the development of large-scale monsoon system is the surface heating (bottom-up formation) and the main factor in the development of subtropical anticyclone is descending of atmospheric dynamics, the main reason for the development of summertime subtropical dynamic anticyclone should be a very strong and unit agent, something other than the summer monsoons.

Geographical studies on food categorized in five scales; global and transnational, national and regional, urban, rural and agricultural, domestic scales of food consumption and the individual as a consumer. Based on this categorization, the present study is placed within urban and domestic scales. By accepting that population of Tehran metropolis will definitely increase in future and regarding that based on systematic approach and limits to grow theory (Meadows, Randers, & Meadows, 2004), no growth in the world will continue forever. We must consider factors that limit the growth of Tehran, besides factors provoke development. One of the limiting factors is the natural and geographical potential of Tehran metropolis. For this research among qualitative methods in futures studies, we chose the scenario, because this method "make the future more real for decision makers to force new thinking and decisions". In the formulation of food consumption scenarios, due to the diversity of stakeholders, the challenges and the types of issues and ambiguities, the approach of the Global Business Network (GBN) was chosen. To analyze the key factors and identifying the key variables the structural analysis method and MickMac software was used. Based on two key variables, technology, and consumer responsibility, four scenarios were created, these are four scenarios: Smart eating scenario, McDonaldization of Society scenario, Food Geography scenario, and Community Eating scenario. In this study, four alternative food futures have been presented for Tehran. In these scenarios, both desirable and undesirable futures are clearly and accurately depicted. The geography of food scenario due to the neglect of the environmental capacities and natural and geographic potentials is the most unsustainable scenario for the future of Tehran. Without scenarios, thinking about the futures of food in Tehran is very difficult and even impossible. These scenarios can help us take into account possible futures in today's decisions. Although this article does not predict a specific future for food in Tehran, But, given the recognition and sensitivity of the events, it can be very useful for long-term decisions.

The purpose of this study is to determine and predict the effects of climate change on architecture using climate models. By clarifying the consequences of the impact of urban architecture on climate change while using the data of surrounding stations with library and field data methods. The climatic parameters of precipitation, temperature and relative humidity of the synoptic station of Miyaneh city during a full period of 32 years (2018-1987) and the possibility of climate change with the models in this city were examined and after obtaining the relevant data Climate change was predicted for the next 84 years through the GCM and SDSM microscale and the AR4 (2007) - HADCM3 (Run 1) - SR-A2 scenarios. In order to evaluate the effects of climate change on the comfort climate of the region, among the bioclimatic models used, the Tarjong model was considered for two periods of 16 and 42 years. In the next 84 years, compared to the last 32 years, the cold months of May, June, July and August will turn into pleasant heat, and in September, the heat will have a great impact on the skin, which indicates a warm climate in the next 84 years. Architectures must be considered.

Summer catchment basins surrounding the city of Tehran, due to their remoteness from atmospheric pollution and urban manifestations, is considered as a place for exploring and recreating for many people, and as a place for money making out of restaurants attracting many tourists for others. Sangan is taken into consideration as one of the most beautiful valleys in Northwest of Tehran. The summer catchment basins due to the phenomenon of counter urbanization and also escape from city pollution, easy access, and short distance, has taken too much attention, so much that the inhabitants mostly spend winter in Tehran and summer there. Since some buildings have been built along the main river, the study of the effectiveness of riparian zone and also the specification of areas susceptible to flood is of great importance. In this research, using the HEC-RAS RAS model, flood- prone areas with different return periods (2 to 100 years old) were calculated, and then for the floodplain zoning the morphological characteristics of the flood zones gathered during the fieldwork have been used. The careful study of these flood fringe zones indicates that a small percentage of the lands are included in flood hazard zone with the 25-year return period. Also, the comparison of the pictures taken from the Sangan River in the past and present shows that the use of lands in the river bank has been changed and due to unauthorized constructions and gardening along the river, the width of the bed has dramatically been decreased. This factor increases the size of the floodplain area and consequently the damages.

It is very matter to study and measure snow covers as one of the important sources of water supply. Due to the hard physical conditions of mountainous environments, there is no possibility of snow measurement. the use of  remote sensing with regard to low costs, up-to-date and extensive coverage in this field can be proven to be a good way to identify in snowflake areas. the main objective of this research is to estimate the surface coverage of Sabalan mountains using satellite images of OLI and TIRS sensors and using the object-oriented classification method. The classification of satellite digital images is one of the most important methods for extracting information, which is currently done with two pixel-based and object-oriented processing methods. The base pixel method is based on the classification of numerical values of images, and the new object-oriented method, which, in addition to numerical values, uses content, Texture, and Background information also in the image classification process. Therefore, in the present study based on the precision of the object-oriented classification, the object-oriented techniques were used to extract the surface of snow cover. In this study, due to the use of high resolution spatial resolution (Landsat 8) and the new method of classification of images, the snow surface was characterized by Normalized Difference Snow Index (NDSI), Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), Brightness with a total accuracy of 91 percent, to 2142.62 square kilometers for the range Sabalan mountains have been extracted and the results can be used as alternatives to snowflake stations.

Tourism is one of the most important means of development in the world. Many countries in the world pay special attention to tourism as an effective tool for their political, cultural and economic development in their country's policies and programs. The present study was carried out in order to plan tourism in Ardebil province based on a futuristic study method. The present research is applied in a practical way as a combination of documentary and survey methods based on a futuristic approach. The research area of Ardabil province and the statistical population is 45 tourism experts, urban and regional planning and executive agencies of the province. Delphi method, cross-effects matrix (Wizard scenario software) and Wizard scenario software were used to analyze the data. Based on the findings of the Delphi method and environmental scanning, 88 factors were identified as influential factors in the development of tourism in Ardebil. In the second step, using the Micmac method, 14 key Factors, including the comprehensive tourism plan, the media, stimulus policies, macro policies of the state, distribution of facilities, infrastructure, recreational centers, increased private incentive to invest in the region, the region's susceptibility to Investment in tourism, planning, security facilities, budget, the existence of hot and mineral water springs, improvement of information systems, such as site and blog, have been identified as key to the development of Ardebil province. In the third step, based on key factors, believable futures were explained using the Wizard scenario method, which ultimately resulted in three strong, weak and believable scenarios. In this scenario, believable scenarios are due to the intermediate between scenarios Strong and weak, have been based on analysis. Accordingly, there are three scenarios named "Golden scenario", " believable scenario" and "Disaster scenario" for the future of tourism in Ardebil province.

Understanding the main components of the watershed water basin and analyzing their hydrologic behavior are among the key components of any planning and management procedures in the field of water resources engineering. Today, the need to use modern technologies in hydrological modeling of watersheds has been discussed more than before. The purpose of this study is the simulation of hydrological components in various land use categories in the catchment area of the Dez river basin. Since the tool used in the research is the SWAT model and the SUFI-2 algorithm, the database used include a range of input data. In order to determine the level of sensitivity of the model to the input parameters, global sensitivity analysis was performed. Then, by adjusting the selected parameters and using the observation current, the model was calibrated and validated for the periods 2007 - 1994 and 2013 - 2008, respectively. The coefficients of NS, R2, P-factor and R-factor confirmed the model's ability to simulate river flow in the studied basin. The results of the model showed that the areas with forest use share the highest contribution to aquifer nutrition, and the barren lands have the highest surface runoff. Surface runoff has the leading role in creating the main stream of the river and after that the main flow has been effective in this area. The forest use change to Agricultural lands and pasture will change the hydrological parameters of the basin, and the result of these changes will lead to the increase in the surface runoff, the reduction of nutrition of groundwater resources and the reduction of river basin water. The SWAT model can be used as a precursor model in watershed management studies.

In this research, coding the rainfalls, prepares daily 45 stations with the statistical period of 20 years to zero and one codes to realize the daily dry periods in west and north west of the country and then, by establishing the main condition of occurrence of code one for 30 stations, we extracted the dry 4 to 10-day frequencies. And the results gained of considering the atmospheric weathering, shows that the most clear rotational pattern in sea level is related to Siberia-Europe high-pressure panels and sometimes both of them that increase the rotation on the region and also, the local high-pressure reinforcement and there is a high altitude in atmospheric middle level which is derived from sample patterns and is placed on the studied region and these sample patterns are from omega, bi-polar and rex models that they are on Russia and Scandinavian countries with some changes. The 500 level TAVA and omega shows well that in most regions, the air course, has decreasing case and so, we can result that placement of a high altitude in atmospheric middle and upper level on the high-pressures of the earth, causes the weather stability and lack of rainfall and as a result, the stability and durability of these conditions for several days, is related to sample patterns.         

Concerning the importance of urban network studies and the role of hierarchy system in population decentralization in metropolitan areas, this paper by using acknowledged indicators and Grade of Membership (GoM) model and using Combined Analysis method has tried to find the changes in urban hierarchy of Khorasan region during the period 1956-2016. The outcomes show that urban system in Khorasan region as the one in the country was afflicted with inconsequentiality by 1986. However, during the period 1986-2006, the urban network in Khorasan region tended to reach to an equilibrium. Nevertheless, it has gone toward an imbalance during the period 2006-16. The outcomes also depict that the models and indicators did not work coordinated. While some indicators (such as Herfindahl and Entropy indexes) showed that, there were an equilibrium among the urban network in the region, some other (such as Primate City and Centrality indicators) showed increasing centralization and inconsequentiality. Accordingly, the study used “GoM model” and “Combined Analysis method” for the final analysis. The GoM used three variables that aimed to make the model more reliable: The Prime City Indicator, the Centrality Indicator and Equilibrium Indicator. With this methodological novelty, the analysis of the hierarchical patterns represented in the model by the multiple profiles were closer to what could be understood as a "methodological ideal", difficult to be applied empirically due to the complexity of the subject, but included in studies theoretically based. As for future studies, which will seek to understand the hierarchical urban organization of other regions of the country and of the world, these indicators may be incorporated if adapted to the regional reality.

Spiritual-led urbanism is being structured as a new paradigm in urban planning. Social inequality, polarization, moral poverty, and a high prevalence of psychiatric disease are only part of the manifestation of the lack of attention to the issue of spirituality in the production of space. Indeed, the challenge of the contemporary city is the emergence of the process of personalization of space production and capitalization resulting from the dominance of the speculative model and its confrontation with identity and semantic structure. In contrast to these challenges, the discussion of spirituality in recent decades by prominent Harvard scholars has emerged as an interdisciplinary paradigm, embedded in a powerful stream of critical communication planning theory and requiring context. Therefore, the present article analyzes the theoretical field of research related to the paradigm of spiritual development in the production of urban space. This article is based on a combination and is meta synthesis. The statistical population of the study consists of 55 ISI and scientific-research articles in the period 2008-2019. In order to collect and data analyze, methods such as systematic review and open coding have been used. In this context, comprehensive form for summarizing and extracting data from selected research was developed which issues concerning public profile and the theoretical framework of the research. The research findings are presented in two parts: structural and content. The first section examines the general features of selected research, the unreliability of studies on the impact of spirituality on urban space production, and the second section elaborates on the theoretical framework of research on spatial spirituality. production of spiritual-

The goal of this research is studying the effect of recent climate changes, espeeially heat rise on the amount of effective  rainfall in the lorestan peovince. Effective rainfall is the amount of fall which, after evaporation, is absorbed in the ground. in the ground.in USDA method and the us agriculture, the amount of rain abstorbed in a growth perlod of a plant and available for its consumption is called effective raifoll. The results showed that the amouent of rainfall in the first period is more than that of the second. The frequency of raining days got reduced  in the after-climate- change period. Heat got increased in the second period. Evaporation was more in the second period. Relation humidity got decreased in the second compared to the first period, and wind speed increased by studying the process of the data changes, it became evident that climate change leads to the increased inconsistent rainfalls in the studied climate variables indicate that under the effect of climate change , Based on Vibol method, droughts caused by effective rainfalls were calculated, and the probability of effective rainfalls in 5 time periods was accounted for. It was shown that in the years 1369 to 1396, effective rainfall in the region was scarce, so it was very influential. With Dobif Model, effective rainfall was analyzed, and years with the least effective rainfall for dry farming with positive signal, that is, appropriate conditions, and negative, that is, inappropriate conditions were recorded. Based on linear coefficient, rainfall trends in the three stations of Khorramabad, Aligudarz and Borujerd. Geographical distribution analysis of   effective rainfall showed that in the south and south-east of the province, the coefficient of effective rainfall was more than the rest of the province. This coefficient was decreasing when it comes to the south-west of the province. Effective rainfall decrease was more due to increasing evaporation happening in this part. the effective rainfall in the studied region got decreased, therefore, preserving underground water resources, on which natural life depend, should be considered more than ever.

One of the most important and urgent issues of urban planning is the equitable distribution of facilities, services and accessibility of citizens at the urban level. Economic and commercial centers, including banks and financial institutions, are one of the most important economic sectors of cities and can be sustained. Social, economic, physical, and environmental impacts of neighborhoods. The purpose of this study was to investigate the extent of citizenschr('39') access to commercial land use in Ardebil neighborhoods. Therefore, the present study is applied in terms of purpose and descriptive-analytical in nature. The statistical population of the study is 44 localities of Ardabil city. Spatial statistics models, Hot Spot Analysis, and GIS software were used for data analysis. Finally, regression function in Idrisi Selva software was used to analyze the correlation between commercial user and population as well as to determine the relationship and correlation of this user with other service users. The results show that in Ardabil neighborhoods there is inequality in terms of overall business use. As a result, the neighborhoods have high commercial use weights and high concentrations of hot spots in optimum condition, including areas 3 and 5 from zone 2, zone 7 from zone 1 and zone 6 from zone 3. Also, commercial low weight blocks and low concentrations of hot spots, which include areas 8 and 11 from zone 2, area 11 from zone 3, are lower in urban sustainability. Finally, based on the results of the research, some suggestions have been made.

In the contemporary century, with increasing development of technology, one of the challenges of contemporary architecture is to find its relationship with the culture. New technologies from industrialized countries with developmental goals are imported in an uncontrolled process. In contemporary Iranian architecture, technology has had a serious presence in various fields. The main purpose of the research was to investigate the cultural transformation of contemporary buildings in Tehran according to the application of technology. Due to the variety of types of use, this study focused on official complex compared to the two periods before and after the Islamic Revolution.The research method used in this research is combined (quantitative-qualitative). First, the components of technology and culture in accordance with contemporary architecture in the office buildings of Tehran have been developed by qualitative research method, then by quantitative research method, the relationship between key factors involved and the share of each component has been investigated. To examine the hypothesis, the relationship of three variables of culture, technology and architecture has been identified. In this study, cultural developments have been evaluated in two dimensions: mental and objective components. The results show that the effects of metamorphosis have had the greatest impact on the objective components of culture, including individual and social strata.Finally, the issue of technology application in contemporary office buildings in Tehran with a culture-based approach has been proposed in the form of a strategic model that will lead to the correct application of technology in office buildings in Tehran.

Proper urban management based on the right methods has always been a serious challenge for urban professionals and has been the subject of various discussions and studies over time. Each city, due to its specific characteristics, experiences special issues that are specific to the city and its surroundings, and in the meantime, creating a single model is not acceptable. Good urban governance is an important principle in urban management, which unfortunately In our country, it faces many obstacles. The present article has been done in terms of purpose, application-development and quantitative-analytical method, which first identifies the most important obstacles to the actual implementation of urban governance in the country and then examines these cases in the study area of ​​Garmadreh. The results show that the factor of lack of integration between different sectors of urban management with an average of 3.8 has the greatest impact on the lack of governance in the country. From the results of the first part, 4 basic effective indicators in the implementation of urban governance in the study area have been studied. In the executive level of Garmadreh city, in the field of accountability index of weakness factor in continuous and public supervision with an average rank of 5.38, in the index of rule of law rule, there are multiple, parallel, interpretable and sometimes contradictory laws with an average rank of 3.73, in the transparency index of factor of lack of access to information 4.56 And in the participation index, the factor of intense centralism and top-down management with an average rank of 4.48 have the greatest impact on the lack of proper implementation of urban governance in the city of Garmadreh.

Tourism plays an important role in rural development. Tourism while enhancing the rural development process through diversification of economic activities, maintaining social integrity, environmental protection, and positive spatial-physical changes in rural settlements can increase the quality of life in rural areas. Due to the importance of this issue, in the present study, the effects of tourism on improving the quality of life of rural settlements were investigated. The present research is descriptive-analytical in terms of purpose and method. The data collection tool was a questionnaire and interviews with rural households. The statistical population includes rural settlements on the shores of the Oman Sea in the south of Sistan and Baluchestan province, the two coastal cities of Konarak and Chabahar (N = 4855). Using Cochranchr('39')s formula and quota sampling method, 356 samples in 12 villages that had tourist attractions were selected as a sample. Descriptive tests, analysis of variance and path analysis model were used to analyze the data and answer the research questions. The results of analysis of variance showed that tourism has a good linear relationship with increasing the quality of life in rural settlements of Konarak and Chabahar. So that according to the route analysis model, rural tourism has different and favorable effects on economic, social, environmental and physical-spatial indicators and the value of p of all Lamda parameters in the above model indicates the confirmation of all regression relationships. Among the four dimensions, tourism development has had the greatest effect on the economic dimension of quality of life and the least effect on the social dimension of quality of life in rural settlements.

 As it can take an efficient step towards the preservation and sustainability of such lands due to the preparation, implementation, and reformation of criteria. In District 9 of Isfahan Municipality, mismanagement in the preservation of ecological lands has destroyed gardens and agricultural lands, and has caused the loss of social unity of neighborhoods. Consequently, the study of ecotourism management in this region is of great significance. For this reason, in this paper, a model for ecotourism management with an emphasis on urban ecological textures is provided for District 9 of Isfahan Municipality. For this reason, first, the Star method has been used as a model for interviewing experts and relevant municipal experts in Isfahan city management. At that point, with the help of library investigations and field assessments, and implementation of the grounded theory method, 3 dimensions, 10 categories, and 35 subcategories are extracted from the data gained from the interview. The main dimensions are urban texture management (with categories legislation, planning, management of resources and control and supervision), the ecological texture (with the categories: protection and development and improvement), ecotourism (with the economic, social, environmental and cultural categories).

System is a set of interconnected components that are systematically interconnected, influenced by one another, interacting with one another, acting as a whole, and being purposeful. A systematic approach is a perspective that allows us to identify the forces and variables that have a significant impact on the environment outside and within a complex and to understand their function and position in the complex. In general, the interplay of form and process in landforms is based on systematic reviews and analysis by researchers and the residual effects of these changes.  In this study, the study of glacial geomorphic systems with regard to systematic approach and the interaction between form and process in glaciers of Oshtorankuh is investigated. Geomorphometric analysis of the glacier cirques of the Oshtorankuh region shows that these landforms, unlike the usual glacier cirques, have been expanded more horizontally and superficially than were investigated in depth direction to justify the genesis and lithology of the area. It is often calcareous and carbonate and the carbonate nature of the environment activates the dissolution process in the environment. Therefore, in this glacier system, the dissolution factor is more effective than other active elements.
