Abstract
Importance of climate change is global. This issue to some extent has been out of human control. Human beings can only provide security and the community with knowledge and management against its negative consequences. On the basis of this research, the present paper analyzes the impact of climate change on Iran, on a small scale and applied to the central catchment area. The findings of the research indicate that climate change has shown the geographic region of Iran in terms of changing the rainfall pattern, decreasing precipitation and increasing its temperature. In the next step, these cases resulted in excessive withdrawal of groundwater aquifers and it has reduced the quality of underground water. This chain has led to the design of inter-basin water transmission projects, which is at least the result of the cycle of social tensions that has occurred in recent years. Considering the geographical extent of the basin and its belonging to one of the most frequent aspects of Iran's civilization, the set of consequences of climate change in the central catchment area, in addition to its impact on various social, political, economic and environmental layers, also has several scale effects. And its destructive effects go beyond national scale and to an extent beyond the scope of Iranian culture. In this regard, the research findings indicate that climate change in the central watershed is influential in many aspects of society and the country, so that if the current process continues, the current Iranian civilization will face a strategic challenge. To this end, at the end of the research, good water governance, as the best way to confront and control the negative consequences of climate change on the central catchment area, and Iran in general, has been argued.

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
The heat wave is a long period of warm climate, compared to the expected conditions in a region over a certain period of the year. Heat waves cause mortality, disease and various problems in different fields of transportation, agriculture, production and energy. It is very important to study the changes in spatial and temporal patterns of these waves to understand the causes of the incident and confront them. In the present study, using the "Heat Wave Magnitude Index daily" (HWMId), which takes into account both the intensity and the wavelength of heat, the heat waves of Iran between 1985 and 2015 have been analyzed in terms of spatial and temporal distribution. For this purpose, using the maximum daily temperature data of 44 synoptic stations of the country and on the basis of the threshold of the 90th percentile, the heat waves greater than or equal to three days were identified at each station. After applying the HWMId on the days of each heat wave, the magnitude of each wave was calculated. Then, the average number and magnitude of all waves, as well as the most severe ones, were calculated in annual and seasonal scales and the corresponding maps and charts were drawn up. The results of the study showed that the highest number of heat waves occurs in the western part of the Zagros Mountains and then the Kavir Plain; while the maximum magnitude of heat waves belong to the south-east and central parts of the country. Autumn and then winter season have a high share of the most severe heat waves during the study period; while the spring and summer heat waves are relatively weaker, and are more limited in terms of expansion. The most severe heat waves during the study period have occurred in the winters of 2008 and 2010. The number and magnitude of heat waves in the country is increasing significantly. The largest increase in the number belongs to the summer and the magnitude belongs to the winter.

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
Any imbalance in intra-city systems (urban spatial and urban areas) and external systems of the city (near and far-reaching districts of the city and region) causes its uncertainty and instability. As a result, estimating the risk and assessing the seismic vulnerability of a city is also considered as a major issue. The present study, with the developmental-applied and combination of field and library methodology and using the VIKOR method, has studied the issue in Ilam province. The results show that the cities of the province in terms of demographic density, literacy, etc. Each of them has an effective role in vulnerability, they can be effective in the damage caused by the earthquake. VIKOR and GIS models show that the regions in which these indicators are higher than other areas (surplus of defined standard) is not in the benefit of the region and if this surplus is in the benefit of the region. Statistically, the average VIKOR score was 0.125%. Though this amount expresses the situation inappropriately. But there are areas where VIKOR levels are much smaller than the average. Which includes the Dehloran, Ivan and Maleshahi cities

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
Technological innovations are known to be effective parameter in developing and designing architectural spaces in metropolis; however the impact of technology on the architecture of different communities in the world is not the same. The purpose of the paper is to depict a clearer view of the relation between culture and technology in contemporary architecture in globalization era. This paper examines the theories in the context of globalization by applying descriptive-analytical method by investigating documents. The results indicate that the relation between culture and architecture in this context based on the viewpoint of the Castells and Giddens and Robertson, that based on the limited boundaries, limitations and network communities, is not weakened, but a new form has taken stand against the unification strategy and represents a kind of unity while pluralism.
The usage of technology includes removing boundaries, flexibility and diminution of distances. This can be investigated not only in the physical dimensions but also in various cultural aspects. The consequences affect architecture and culture that can be maintained by retaining the transcendental concepts of the past rather than superficial imitation of culture and technology in order to redefine new layers with the introduction of technology in globalization era.

Abstract
Gender distribution in the centers of power and the level of participation in elections from a gender perspective are among the ambiguous issues that show the composition and quality of power structures in political-spatial units. From a geopolitical perspective, how power is distributed through representation and political participation through elections reflects the presence or absence of gender justice in power structures. Given the high geopolitical weight of women in the Iranian population pyramid, the present study has reviewed the city and village council elections in Fars province from a geopolitical perspective of gender. For this purpose, by using descriptive and survey methods and by examining different statistics and data in the three rounds of city and village council elections in Fars province, the gender distribution of the elected representatives in these three rounds has been investigated. Is. The results showed that in the first round of urban and rural elections in Fars province, men held 90% of the seats. In the second round, this ratio reaches 80%, and in fact, there is a relative improvement in the gender distribution of representatives. In the third round, however, the sinusoidal trend reverses to the first round so that the gender weight of the representation remains established in the masculine structure.

Abstract
Various satellite remote sensing data, images and products have proven their place in drought, drought and agriculture studies since the production of this type of information resource. Visible, near-infrared and thermal bands are among the most widely used in the production of products such as vegetation and surface temperature. In this study, from MODIS sensor data to investigate and find the coefficients of spatial relationship between vegetation-surface temperature index (NDVI-TS) and NDVI-ΔTS to extract the time of agricultural drought from June to October 2007 to 2010 in the catchment Siminehrood has been extracted from the Temperature-Vegetation Condition Index (VTCI) and the Water Lack Index (WDI), which are able to detect drought stress on a regional scale. The results of this study showed that in both indicators, the drought stress situation was higher in 2007 and 2008. Also based on the NDVI-TS space relationship in all the years 2007 to 2010 the high slope of the triangular space for the hot edge is negative. This means that with increasing NDVI, the LST level decreases while for the cold edge the slope is positive. In addition, the slope obtained from the NDVI-ΔTS space relationship is negative for the dry line, ie the dry line or the minimum transpiration-sweat line (ETR) shows a negative correlation with NDVI. While for the wet line, especially in 2010, the slope is positive and in other years, no significant change is seen. The present study showed that the VTCI threshold for drought stress was severe in 2007 and 2008.

Abstract
Leisure is an integral part of everyday life in today's world. Today, leisure is a new social arena in which various factors influence. Understanding these factors and examining their role and their impact on active (external) and inactive (external) leisure has been a major part of proper city management since this day. Therefore, in this study, using exploratory method, we sought to identify the factors affecting leisure time in district 22 of Tehran. This is a cross-sectional, applied research. The method of data collection is survey and its tool is a questionnaire. This study, using inferential statistical methods and SPSS software and statistical analysis such as correlation, regression and t-test, attempted to analyze the relationship between independent research variables (functional, security, aesthetic, transportation, economic, biological). Environment and infrastructure facilities) and the dependent variable (active and inactive leisure time), to identify the maximum impact and the least impact of the variables. The results showed that the effect and correlation of factors on leisure time (active and inactive) were different. In other words, indoor or passive leisure time is less affected by the external environment and context. But on the other hand, leisure time active or foreign in the 22nd district of Tehran is strongly influenced by background conditions and the external environment. Aesthetic variables and infrastructure facilities have the highest relationship with active leisure time and economic, performance and economic components have the least impact. In the passive leisure time, most of the impact factor is related to infrastructure and least to economic component.

Abstract
Dust is referred to sediments of less than 100 microns in size which are transmitted as suspended particles. Dust storms are events which naturally occur in arid and semi-arid areas, especially in subtropical latitudes. One of the most known sources of dust is the west of Asia, including Arabian Peninsula, Syria, Iraq, and Iran, especially Khuzestan Province. The purpose of this study is to investigate the frequency and trend of dust phenomena on hourly, monthly, seasonal and annual scale between 1995 and 2015 in Khuzestan Province. The method in this study is based on statistical computation of dust parameters and also the trend analysis of data based on Mann-Kendall test and spatial distribution maps of dust phenomena. The results suggests that 78.57 percent of dust event are occurred between 9.30 am to 15.30 pm local time, concurrent with peak of sun radiation and earth surface warming, dryness of soil and local pressure difference. The hourly trend analysis is increasing and significant in all hours and the highest increase occurred at 9.30 pm to 12.30 pm.49 percent of dusty days occurred in June, July and May and also 73 percent of them are in spring and summer as following from temperature increase and water and soil resources drying in the province. The seasonal and annual spatial distribution of dust indicates that most of dusty days in all seasons are located in west of province which suggests dominance of external sources as the main source of dust and the importance of topography factor in this area.The Z value spatial analysis suggests high increase of dust event in recent 20 years in southeast, south and central areas of the province and also on last hours of day which demonstrator development of internal sources activities in increasing trend of dust event in recent decades.

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
Radar sensors obtain regular and frequent radar images from which ground motion can be precisely detected using a variety of different techniques. The interferometric synthetic aperture radar (InSAR) is utilized to retrieve the spatial characteristics of the largest coseismic landslide Maleh-Kabood, induced by the Ms 7.3 Azgleh earthquake in Kermanshah Province, Iran. The available seven interferometric pairs with good coherence selected from the Sentinel 1, 2 imagery data covering the NW-Zagros mountainous area are used in the study. The post-seismic topographic change relative to the pre-seismic over the landslide area is spatially mapped from the persistent scatterer network adjustment solution. The quantitative estimation of local elevation change, mass sliding volume and deposit thickness associated with the landslide is conducted. The spatial pattern of mass movement suggests that the giant landslide is characterized by a major sliding length of 3570 m along the NW–SE directions with an extension width of 1500-2300 m along the Maleh-Kabood and Ghoch-Bashi gully respectively, and a peak height change of 20 m in the vertical direction neat mountain ridge. The affected area of landslide mass movement reaches 6.0 km2 (577 Hectares) with the volume up to 500 million m3. Comparative studies indicated that the Maleh-Kabood landslide is the largest landslide in Iran over the past few centuries. The study also demonstrates the potential of InSAR technique as an alternative to allow the quantitative measurement of mass wasting volume associated with earthquake-induced giant landslides.
