Abstract
Iran's vast country has different geographic conditions. As of the thirteen known climates in the world, it has eleven types. This has made many environmental, natural, recreational and economic benefits. The purpose of this study was to investigate, identify and introduce the geotouristic capabilities of Ghezelowzan Basin based on the Fassoulas method. The catchment area of the Ghezelowzan is a landform of various quaternary processes that are changing. Identification of geosite plays an important role in explaining quaternary developments. The research methodology is based on description and analysis, which is described as a field study of the library to describe and describe the region. The selected geosites were then positioned on topographic maps of 1/50000 and using geological maps of 1/100000 of the region, the lithology of different landforms such as hoodoos, Behestan dom, salt domes Chehrabad, Pari lakes, copper mine Baiche Bagh, dikes Sedimentary, cuesta-like forms, kalut-like shapes, Kcadovan-like shaped forms, glacier circuses, and tectonic valleys-fridges. After identifying landforms, one of the most common and comprehensive geotouristic models called Fassoulas was used. The criteria defined in this model were defined in six main categories: scientific, ecological, conservation, cultural, aesthetic, economic and potential use. By assessing landforms in this model, it was determined that the chimneys of the Jen, Behestan, dome, Darband Ghaterchi valley and salt Dome of Chehar Abad were selected as the most suitable geocites for obtaining the maximum scientific and ecological score, while the Belogice glacier landform was also the lowest.

Abstract
Channel retreat are an important process in the river's morphodynamics, which affects channel variation, flood plain development and habitat development. Structures and farmland the border of the Lavij River Faces the risks of river bed change every year. Therefore, there is a need for a reliable method to determine the river bank retreat and predict the river bank Stability. In this study, with the aim of investigation of the risk of erosion and identification of areas susceptible to erosion in the Lavij River, Using BEHI and NBS models, the risk of side erosion was determined in 7 sections of this river. The results of the NBS model using the tnb / tbkf index showed that the rate of erosion of the Lavij river bank in all studied cross sections, except for cross sections 2 and 6 ,erosion rate is high and very hight. According to the indicator (dnb / dbkf), the bank erosion rate of the Lavij River, except for sections 4 and 5, is approximately consistent with the erosion trend obtained from the first index (tnb / tbkf). According the BEHI model, cross sections 5, 4, 3, 1 and 6 show a high incidence of instability and have a great potential for bank erosion and sediment production. Also, cross section 2 shows the medium instability status. Cross Section 7 and 2 show a high degree of instability, which has a high potential for bank erosion and sediment production. Finally, Kruskal-Wallis statistical test was fitted to evaluate the results matching and the results showed that all three indicators were almost identical to each other in the assessment of bank erosion.

Abstract
In this research, while studying climate conditions in the current period and analyzing changes in temperature, precipitation level, and the sunlight received, current conditions were also analyzed based on daily data from synoptic stations in the region, which had meteorological data recorded for at least 30 years. Given the environmental conditions necessary for the growth of rice, the availability of its phenological data, its high-low temperature thresholds, the Degree Day systems needed for the completion of its life cycle, and the phenological processes related to its economic production, a suitable agricultural calendar was specified. During the March-July period, this calendar showed variations in different provinces. Based on the current temperature conditions and the probable continued warming trend of the planet in the decades to come, nwoDscale was applied to the output from the atmospheric general circulation model MCdaH3 under scenario using LARS-WG5 model. In this study, years between 1969 and 1990 were used as the base period, while years between 2046 and 2065 were studied as the future period. Temperature and precipitation conditions for the future period were simulated. Obtained output was then studied and compared with temperature conditions that were suitable for the plant to grow in the region. With some differences, results showed that the agricultural calendar for rice in Gilan and Mazandaran provinces will shift to winter. Given the different temperature conditions of Golestan province, its agricultural calendar will shift to spring.

Abstract
Using Landsat satellite images taken in 2015/08/10 and also SEBAL and metric methods, surface albedo amounts for various land uses in the northern half of the Ardabil province was estimated. ENVI4.8 and ArcGIS10.3 softwares were also used. To determine the type of usage of different levels, the maximum likelihood algorithm classification method was used with Kappa coefficient of 86.14% and overall accuracy of 92.63%. The results indicated that the water levels with the mean value of 0.93 and 0.414, respectively, had the least amount of albedo in SEBAL and METRIC methods. Also, based on the results obtained from SEBAL and METRIC methods the city albedo is about 0.313 and 0.278 respectively. These values are the highest levels of albedo among Land use levels. In this study, the amount of albedo in rangelands was determined to be between 0.183 to 0.266 in the SEBAL method and between 0.237 and 0.265 in METRIC method. The amount of albedo was also examined in agricultural (0.240 based on SEBAL method and 0.247 based on METRIC method) and forest lands (0.149 based on SEBAL method and 0.225 based on METRIC method). Finally, according to the results of Albedo values based on SEBAL and METRIC methods, it was concluded that due to the difference in net energy received at different levels, it is possible to estimate the level of albedo levels, which is very effective in estimating evapotranspiration by remote sensing methods.

Abstract
The importance of retail in the marketing process has become weaker with the development of shopping centers today, The growth of shopping malls in the metropolitan areas of Iran has been increasing over the past few years and there is no longer competition for retailers. Therefore, surveying the behavior of consumers in their shopping centers is a competitive strategy for the owners of these industries in order to compete with retailers and other shopping centers. The statistical population in this research is Shopping centers of Tehran, Isfahan, Alborz and Mazandaran. The method of selecting shopping centers based on artificial intelligence studies has been done through genetic algorithm. The criteria for choosing the centers are optimal according to the principles of urban management. Using a conceptual model through structural equations of partial least squares, using the Smart PLS software, the statistical population of the study was 384 people. The results showed that the variables of beauty, escape, role play, comfort, brand identity, social responsibility, and impunity affect consumers' behavior in shopping centers, The results of this study have been able to provide a native model with respect to the structures of shopping centers in Iran.

Abstract
Many factors, including cultural factors, currents and schools of thought, and patterns of urbanization in the world are influential in the physical structure of a city. The physical structure of the city is the result of all the forces that give rise to the formation and formation of a settlement and has an objective and mental appearance. The growth and development of cities, due to various events in all historical periods, has been declining and rising. Nowadays, knowledge of the physical structure of the city and the reasons that govern its spatial expansion in different periods is necessary to control its expansion and is one of the important factors influencing the success of urban planners and designers. This study was written with the aim of identifying and prioritizing cultural factors affecting the physical structure of the city with emphasis on indigenous architecture. The present research is applied in terms of purpose and descriptive-analytical in terms of method. Library and field methods were used to collect information. The statistical population of the study consisted of experts and specialists in architecture and urban planning, with a sample size of 30 people. In order to achieve the objectives of this study, the fuzzy Delphi technique and the BMW model were used. The results of fuzzy Delphi technique confirmed the identified factors and sub-factors. The results of the BMW model showed that among the identified factors, the privacy factor with a final score of 0.298 in the first place, the security quality factor with a final score of 0.273 in the second place, the nature connection factor and social interactions with a final score of 220 / 0 is in the third place and the hierarchical factor is in the fourth place with a final score of 0.209.

Abstract
This paper focuses on convergence with the measures and activities of the global assemblies in order to promote the resilience of cities against earthquakes and to pay attention to their physical- skeletal development process, to analyze the resilience of the city of Zanjan and to design scenarios against the earthquake hazard. The criteria used in order of priority and importance include: type of structure, building quality, building life, number of floors, occupancy level, enclosure coefficient, building density, grading, distance from the fault, number of units in the building, user adaptability, slope and facade Building, Which are applied in the three earthquake resilience scenarios after analytical hierarchy analysis (AHP) based on (relation No. 1).
According to the maps drawn from the scenarios, the resiliency rate in the central and southern parts of the city was weak and very weak and as far as we move north, west, and east, we increase the amount of physical resilience of the area. However, no resonance images in the scenario maps show any area with a very resilient domain. As in Ramallah scenarios 7 and 8, the resilience is in a non-resilient and very weak domain. The analysis shows that, according to the maps in any of the areas, there is no stability in the resilience That is, no area in the assessment of all criteria is resilient.

Abstract
The purpose of this study is to investigate and analyze turbulence, fluctuations and jumps of Iranian regions. For this purpose, environmental data has been gathered in two parts. In the first part of the data, the results of the interpolation of the daily precipitation observations of 1434 stations of climate and climate were used from the beginning of 1340 to 1383. After the formation of a database to identify the Iranian regions, a cluster analysis was used on average data and annual and monthly rainfall variation coefficients. Silhouette analysis has been used to validate the Iranian rainy areas. In order to investigate disturbances, mutations and fluctuations in Iran's rainy areas, this study was carried out. The results of cluster analysis indicate that Iran's peripheral areas are divided into six classes. In the meantime, the Caspian region (area 4) has the highest rainfall and the lowest coefficient of variation. The distribution of rainfall regime in each of the six areas shows that Iran's precipitation regime is more frequent in winter and spring and sometimes in autumn. Investigation and analysis of rainfall turmoil has shown that rainfall, except in the 4th district (Caspian region), in other areas of distribution of rainfall occurred along with disturbance. Although most disturbances occur in the zagros area, the highest sequence of disturbances is related to the fifth load region. The least sequence of disturbances occurred in the central and eastern part of the country. The results of mutation analysis and fluctuations indicate that rainfall disturbances, except in the early years of precipitation regions two and five in other regions of the other regions, have no significant mutation, while short-term fluctuations of 3-5 years on rainfall Each of the six domains has dominated.

Abstract
Livestock farming is one of the most important activities in rural areasand most villagers, along with agriculture and horticulture, are engaged in animal husbandry (Livestock storage) and some products of the villagers in the agriculture and horticulture sector are devoted to livestock feeding, and others are consumed or sold, such as lob bits, live meat and etc. The purpose of this research is to analyze the effects of livestock economics on sustainable rural development. The present research is applied in terms of purpose and is descriptive-analytical in terms of its nature and method. Library and field studies have been used to collect data. The study area is East Gavdoul District in the Malekan County. According to the census of this region, there were 2306 households and 7468 inhabitants in 2016. According to the Cochran formula, 283 households were selected as the statistical sample of the research. This sample was randomly selected from households with livelihood economics. To analyze data on inferential statistics, one-sample t-test, regression, analysis and performance diagrams were used. The results of this study showed that there is a positive and meaningful relationship between livestock economy and sustainable rural development with a correlation of 0.400 and significance level of 0.30; So, for the dimensions of livestock economics, the economic sector with the impact of 0.743 and the social sector with the impact of 0.355 have the most impact on the sustainable rural development in the region. Also, the physical section with an impact value of 0.176 has had the lowest level of impact on sustainable rural development in the region. The general results of the research show that the economic sector with 0.41% and the social sector with 0.31% have a positive effect on the development and expansion of th
e livestock economy of the area.

Abstract
Increased urbanization, population growth and socio-economic and environmental problems besides growth and development of ICT at the global level are the sign of the 21st century. The contradiction between economic growth and environmental protection, encountering ultra-modern citizens with industrial cities and lack of responsibility to current citizens has led to a smart sustainable city that thanks to ICT such as IoT following to solve mentioned problems. This paper beside introducing smart sustainable approach as a counterpoint to Neoliberal approach, assessing emergence, evolution, aspects, indices, and differences between similar approaches like smart city. This research from the view of aim is basic research and from the view of nature and research method is descriptive analytic one. The results of the research indicate that also there is no universal definition of smart sustainable city, but there is an agreement on the final goal to obtain sustainable development. The reason for this necessity is the third wave of sustainability and crisis of social, economic and environmental challenges in the context of the cities. Also, primary focus of these definitions is equity and social inclusiveness, quality of life, efficiency, flexible infrastructure, ICT and environment protection. Furthermore, there was such a futuristic gap in the definition of smart sustainable city that a new definition presented based on future study approach. In contrast to similar approaches, the core of the smart sustainable city is ICT and environment protection. Also, results shows that for implementation of this aprroah inaddtion to use theory of change, future study and systems theory, should consider the slogan of “think globaly and act localy” and localization of smart sustainable approach based on social, economic, political and futuristic condition of Iranian metropolises.

Abstract
The coastal are geographically diverse from important areas for attracting populations and economic activities, especially military ones. Understanding the natural environment's behavior on the coast can help plan and deploy military activities. Therefore, this study evaluates the role of natural factors (climate and geomorphology). For this purpose, the most important variables affecting the location of military activities are selected, and then the data of the weather stations of the region for a period of 30 years to create climate databases and layers of features of the earth's surface including slope, tilt, topography, etc., for The formation of natural databases was selected and organized in the GIS environment. Then, using decision-making methods (AHP, ANP), we evaluated the impact criteria in the locational process. Ultimately, using the Fuzzy Collaborative Model, the final map provided the best places to deploy military equipment and equipment on the coast of the Oman Sea. The results showed that more suitable locations are located in the eastern coastal strip and some western locations. However, scattered locations with the least vulnerability and non-operational basics can be found in the coastal areas in the final map.

Abstract
The route optimization process is one of the analyzes that can be used when there is a constraint on resources and time, including post-earthquake conditions. In this research, this analysis has been used to solve the Travelling Salesman Problem. In this case, the goal is finding the shortest path between a set of points and the algorithm will try to minimize the transmission costs and target function. This paper due to target, is practical and developmental, due to doing method is descriptive and analytical and due to information gathering method is documental and surveying. In order to implement this problem, by considering to the strict scenario of accessing resources, two algorithms including the Ant Colony Optimization and Imperialist Competition Algorithm in the MATLAB environment with the Dijkstra algorithm in the GIS environment have been used. The view points of the model are areas that prepared to temporary post-earthquake settlement in Gorgan city and the spatial and temporal real-time distances in the urban network are used instead of Euclidian distances. The results of the implementation of the model have shown that the Ant Colony Optimization has performed the route optimization in two parameters of time and distance more effectively than the two dijkstra and Imperialist Competition Algorithm.

Abstract
Generally speaking the existence of metropolises, alongwith the high various business districts have led to high valume of travels to these centers.The density and separation of these centers brings about the increase and the decrease of the vehicles. The adoption of location determination strategies and that of the comunicational centers and the city activities has made the cities continue the developement process while cosidering the fairly service destribution and the spatial equalities.The goal of this research is the recognition and determination of the city spatial organization working centers and activity model and the relation of service functioning with one another so that the mono central and poly central cities can have a important effect on the destribution system and service centers and the vast changes of the citizens .The analysis method is a kind of quantity and quality one. In the quality part of that the descriptive statistics ( the geometrical presentation , graphical disparation, the centralism measures) and the Hansen Model. In the areas of planning, a great difference is seen in the levels of land uses so that the land use of higher educations in the western metropolitan city of Mashhad area is 84 percent while that of the eastern area is 3 percent. It is the same about the equipped medicinal, commercial and green space areas.Only in the areas of managerial levels there is a relative balance. Finaly the city is devided by three areas throughwhich while considering the employment , the developement potential and distance , the land use determining rate was found out.

Abstract
Our country Iran is not far from the global changes of cities. One of these changes is the smart mobility that is Undeniable and inevitablein urban management today. Especially in metropolises, which are facing increasing population and various economic, social and environmental problems. In fact, metropolises always have many problems, most importantly transportation. Shiraz, as one of the major cities and one of the major cities of the country, has a special place. This position is of different cultural, historical, political and other aspects. Its population growth rate has also been steadily increasing due to its location. This trend of population growth over the past few decades has created problems and obstacles for sustainable and desirable management, most notably problems in the transportation sector. The same trend illustrates the need to emphasize smart systems in this city. Therefore, in this study, it is attempted to investigate and analyze Smart Urban Mobility and Social Sustainability for Shiraz. The research method is descriptive-analytical and based on documentary and origin studies. The results show that the mobility and displacement variables are in poor condition based on different dimensions of access, sustainable transport as well as ICT. Different indices of each of these dimensions point to the same issue, as its level of evaluation (significance level less than 0.05 and average lower than the criterion) points to their undesirability from the point of view citizens. The study of the impact of smart mobility indicators on Social Sustainability also shows that smart mobility indicators account for 23% of the total variance of Social Sustainability. On this basis, it should be noted that the mobility variable does not have an appropriate position in Shiraz, and this has not only affected its development process in recent decades, but also poses many challenges for its future development. The growing trend of the population and on the other hand the various social and cultural features as well as tourism are evolving in such a way that it requires a major focus on a systematic transportation based on smart city approach.

Abstract
Interactions and sometimes contradictions in economic and cultural priorities which happen due to social transformations, changes in paradigms and changes in economic – political systems led to changes in urban regeneration concept. The role of culture in urban regeneration had significant changes comparing to other factors; and the cultural focuses became the main approach in urban regeneration in recent decades. The quality of built environment and level of residents’ satisfaction plays an important role in regeneration policies of target areas as well. This study investigates the impact of environment quality variables (environmental, physical, economic and social) on level of residents’ satisfaction in cultural neighborhoods of Kerman, with the goal of improving the regeneration process.The method of this research is applied-developmental in terms of the aim, and descriptive and causal comparative in terms of the nature. This study uses questionnaire as a tool for collecting data. The study sample size is 513 and the data were analyzed by SPSS and AMOS softwares. The results demonstrate a significant direct relationship between economic and physical variables as well as social variables and consequently the same relationship between economic and the sense of satisfaction. The results also indicate a significant inverse relationship between environmental variables, which are effective on sense of satisfaction, and economic variables. The results of structural equation modeling (SEM) show that improvement in the condition of economic, physical and environmental variables, will improve condition of social variables and the sense of satisfaction in the studied neighborhoods. Furthermore, analysis showed that economic variables have more effect on social variables and eventually on the sense of satisfaction as compared to physical and environmental variables. Therefore, the negative effects of each four aforementioned factors could be decreased in the studied neighborhood through planning and application of culture-led regeneration policies. Accordingly the increase in the sense of satisfaction would improve the revitalization and sustainability in these neighborhoods.

Abstract
The aim of this study is to identify the spatial distribution of Vertically Integrated Moisture Flux Convergence (Vertically Integrated) Moisture Flux Convergence) on Iran’s atmosphere. To achieve this aim, the monthly ECMWF gridded data used during the period from 1/1979-12/2013. First, based on the specific humidity content in the atmosphere, troposphere divided into three layers (850-1000hPa), mid (700-775hPa) and upper (500-600hPa). In order to achieve VIMFC spatial variations on Iran, spatial self-correlation methods of globular moron and hot spots used at 90, 95, 99 and 99/99 percent significance levels. The results of this study showed that the spatial distribution of VIMFC in Iran during the first layer of troposphere and especially during warm months of year has a high cluster pattern and in cold months of the year and in the third layer of troposphere cluster pattern decrease. Based on the hot spots index in the first layer of troposphere low height regions, in the second layer of troposphere the high regions of the Alborz, zagros and central mountains and in the third layer of troposphere alpine regions of central and eastern Iran's mountains has positive spatial self-correlation (hot spots). The results show that in winter and autumn during the second period (1999-2013), the range of hot spots of the VIMFC show a significant reduction compared to the first period (1979-1998) on Iran.

Abstract
Groundwater resources are important part of the sweet water available to humans. The present study studies and evaluates the quality of water resources of karstic basin of Roein Esfarayen. For this purpose, sampling of water from water sources was carried out and groundwater quality of the area was evaluated in terms of drinking, agriculture and industry using Schoeller, Wilcox and Langelier diagrams, Water Quality Index( WQI) and groundwater quality index (GQI). According to the results of the analysis of the samples taken and the relevant charter diagrams, most of the water sources in the area were in the good category for drinking. The results of the Wilcox diagram showed that only S7 (Springs of Zargara), S6 (Springs of Sarang Zwucha) and S20 samples (rivers at the basin outlet) had saline water but could be used for agriculture and the rest were suitable for agriculture. The water quality table of the region's springs in terms of industrial use also showed that all of the water samples of the region except the Springs of Sangvah, which contains sediment-bearing water, have corrosive properties. The WQI index is also indicative of the quality of all samples taken in drinking water, and only the surface water of the basin outlet whose WQI is above 50 is in good condition. Location and quality zoning of drinking water from the GQI index was also carried out. The GQI quality index in the region varied from 93.42 to 95.87 in the region. Therefore, it can be said that although the minimum quality of samples is related to surface water of the basin, but this quality value is also in the appropriate quality category. Therefore, in total, all the water resources of the study area are in the category of quality in terms of drinking water standards

Abstract
A new urbanism theory has emerged in recent decades in response to numerous urban problems of the twentieth century, with the goal of creating vibrant, compact, diverse and desirable cities in terms of work, walking, life, and transportation options. In view of the widespread acceptance of this theory among the Iranian researchers, the aim of this study is to assess the sustainability of organic and planned neighborhoods in Mashhad based on the spatial-physical indexes of new urbanism. In this regard, two neighborhoods, RahAhan (organic neighborhood) and the second phase of Rezashahr (planned neighborhood) were selected. This research method is descriptive- analytical and the mixed model of AHP and GIS has been used to assess the stability of two neighborhoods. Accordingly, the Sustainability Measurement Model was used as a hierarchy in the form of 7 physical-space indicators (type of road, pedestrian width, land use, area of lots, access to the center of the neighborhood, number of floors and access to public transport) . Tthe research results show that in Rezashhar, 68.43% of neighborhood area has moderate to high stability and 31.57% of the total of the neighborhood area is the lack of stability, and in RahAhan, 70.84% of the total of the neighborhood has moderate to high stability and 29.16% of the total of the neighborhood is lack of stability. Therefore, according to the spatial indicators of the new urbanism, the neighborhood of Reza Shahr is more unsustainable than the old neighborhood of Rah Ahan. Therefore, this study shows the richness of traditional Iranian urbanization and the superiority of old neighborhoods. So, it can be said that traditional and organic urbanization is a more appropriate basis for applying the new urbanism approach and this approach can be used in the form of urban regeneration.

Abstract
In today's urban planning, the paraphrastic processes of symbolic systems in the city, which aim to show the social and cultural meaning of the physical environment, have received less attention, and most urban contexts, regardless of significant and identifiable differences and similarities and the hidden values in the context and the patterns of traditional urban planning and architecture of Iran are formed, and this makes it important to analyze these processes. The object of this paper is to present a framework for considering change of semiotics system caused by factors affecting the urban identity and comparing these systems in the old and new textures of the city by layered attitude toward the city as a multimedia text. The research is qualitative and the method of research is descriptive-analytic analytic and Semiotics has been used as a tool and method for considering representations and analyzing the identity of the city. Studies in the old context relied heavily on documents and in the new context is field and the samples were studied in hot and dry areas of Iran.The results show that based on the study of representations in the symbolic system in the textual layers of the city form, the duality of meaning and identity of the old and new textures of a city over time indicate several main factors of change within the textual layers of the form of city, the rupture and duality in the human layer and change in the system of codes that affect the structure of the city form, which is manifested in the elimination, replacement or change of signs in the natural, social and artificial layers.
