The first step in natural resources management and development plans is mapping and identification of areas with landslide hazard potential. The purpose of this research is evaluation of landslide hazard of Oghan watershed basin in Golestan province using Fuzzy-based model. For this, first Landslide dispersion maps of the basin were prepared using aerial photos, geological maps and field studies, then map of each of the effective factors in landslide occurrence such as (elevation, slope and aspect, lithology, rain classes, land use, distance from fault, distance from streams and roads) as information layers in Geographical Information System (GIS) were prepared and have been used in fuzzy-based model. After standardization of each mentioned layers using fuzzy membership function and combination based on fuzzy operators (sum, and, or, product and gamma), map of landslide hazard zoning was prepared in four danger classes that are low, medium, high and very high. Results, in comparison with other operators, showed that zoning map of the Gamma fuzzy operator (0.5) with quality sum(Qs) of 1.17 has the highest accuracy and Sum, And and OR operators with Qs less than 0.039 have the lowest accuracy in landslide hazard zoning of Oghan watershed. Key words: Mapping, Landslide, Fuzzy model, Oghan watershed, Golestan Province. Extended abstract Introduction Landslide is one of the most destructive natural events in steep areas. Due to its geographical position, climatic and geomorphological conditions, population increase, pressure on natural resources and land use change, Iran is exposed to natural hazards like landslide. Therefore, identification and preparation of natural

Abstract Salt diapirism is the process of penetrating evaporite minerals into the upper layers leading to formation of special morphology which are important due to oil resources, human settlements and bypass roads. Therefore, researchers e.g. Talbot (1979), Moores (2007), Harding (2015), Arian (2015), Saket (2005), Afifi (2009), Rajabi (2008) and Zamani (2013) have been studied this phenomena in Iran. study area is located in the east of Shahrood which is one of the areas affected by salt diapirism concluding to special morphologies that their approximate age back to Miocene period. In addition to salt diapirism, likely Jylan- Farashian fault in north, Jylan anticline in center of the region caused to create some fractures that through them salt penetrates the upper layers and developed salt morphologies. The effect of the dissolution process plays an important role in the formation of salt caves in the region that for the first time in the study to be considered. In addition, mechanisms such as salt difference density, erosion and anthropogenic factors have an important role in salt forms. Diapirism geomorphological effects of salt are observed in the form of salt domes, joints and fractures, secondary folds, salt caves and salt valleys, polygons, glaciers, springs, cones and cauliflower shapes. In this paper, using field studies, satellite images of Landsat(ETM+) and DigitalGlobe as well as digital elevation model (DEM) datasets acquired from SRTM sensor, the impact of salt diapirism on the morphology of the studied area is investigated aiming to the results be used in future construction activities of the region.

The main purpose of current study is to evaluate the effective causes on citizen's willingness to adopt with the electronic city in different levels. In this regard, this research has been studied this issue by selecting Ahvaz, Behbahan and Mansooriye cities as the representative of different levels- metropolis, medium size and small cities- using survey methodology. The results show that between the different urban stages, a meaningful difference regarding the will of accepting electronic cities exists among the citizens and a hierarchy pattern rules over them. Such as metropolises have a stronger will to accept the electronic cities while mediocre and small cities have shown less interest. regarding the planning and effective factors on the citizens' will, despite the existing similarities in some cases, a meaningful difference is detected among the variables and of the case study cities, thus, each of them requires its own specific approach. according to the results, the metropolises are noted as the priority targets to establish electronic cities and in order to succeed, plans of changing the citizens' views on security and trust in the electronic cities should be places first in importance, and then comes developing the citizens' electronic fitness and also drawing their attention to the usefulness of electronic urban services. The mediocre cities are places second in priorities after metropolises to establish electronic cities and need to have the citizens' mindsets changed into more positive ones about the electronic city merits and to choose proper approaches in developing their fitness, regulate and advertise the electronic city ideas and its concepts and images to raise the public awareness. The small cities stand in the last priority with the need of increasing the awareness and introducing them to the ideas and concepts of the electronic city plans and construct their positive views about the project

Geomorphology of the river, a term used to check the river system. Zohreh river is one of the rivers in Khuzestan that consisted from 2 arm Fahlian and Kheyrabad it flow to Persian gulf at the end of Hendijan flat. To accomplish this study topographic maps, remote sensing data, including: Landsat satellite images, Landsat TM and ETM + collected from the Geological Survey of America (Earth Explorer), aerial photographs taken in 1334 of National Geography Organization is used. Next, aerial photos of 1334 as the base image and satellite image of Landsat 8 (2015) were selected as the data terminal. The future direction of the river in 2030 (1409) is plotted and compared with other periods. In this interval is 2 Meander complained. The findings suggest that during the period under review trends in three periods studied are quite different in the river, so in terms of reducing the length, intervals 7, experiences the lowest decline while interval 2 experience biggest decline in three visits. In terms of increasing the length, intervals 7, experiences the lowest increase and intervals 8, had the largest increase. The findings indicate that during the three periods under review, the river changes in the periods studied are quite different. The results show that in 1955 10 cases of amputation has occurred in the river channel and along the river has become 3,653 km shorter. Even though at intervals of 1 to 5 we except villages along the way, there is no human factor; But in the interval of 6 industries are seen. Interval 7 in the northern part of the land is under irrigated agriculture. But in the southern part are bare. In the interval of 8, lands under the tide, and asphalt and dirt roads are important feature.

The study area in this research is Dasht village located in North Khorasan Province and Besh Oily Village in Golestan Province. The purpose of this study was to investigate and compare the various flood management practices in two flood plain villages (with a set of structural and non-structural measures) and Besh Oily village (displacement of settlement and resettlement). So, as with most surveys, by focusing on a limited sample of the entire community and using the questionnaire, the required data was gathered. The statistical population of this study is the residents of Dasht plain located in North Khorasan province (a set of managing and structural measures for flood control) equal to 391 households and also residents of Besh Oily village in Golestan province (displaced in a limited extent) equal to 129 households. The questionnaires include four variables related to the subject of research, including social (9 components), economic (9 components), psychological (5 components) and bioenvironmental dimensions (6 components). Questionnaires have been basically formed of closed questions with answers in the five-point Likert scale. In the next step, after filling in the questionnaires and removing probable deficiencies, the required information was extracted from the questionnaires and analyzed to achieve the objectives of the research. For this purpose, the statistical method of comparing the means and the panel design based on the attitude of the sample population in the two periods before and after the implementation of flood management measures were used. The results of the analysis of the single-sample t-test of the studied patterns showed a significant difference in both patterns in terms of social, psychological and bioenvironmental dimensions. Also, the findings from the aggregation of the explanatory items of the economic dimension indicate a significant difference in this dimension in the structural and nonstructural model and the average level of the items. Also, the results of independent samples t-test revealed that there is no significant difference in social and bioenvironmental dimensions, however there is a significant difference in the economic and psychological dimensions between the two studied patterns.

Identifying various natural phenomena is essential for many scientific branches. geodiversity has provided the foundations for providing the living conditions of modern societies and puts it at the disposal of man natural resources, such as construction stones, aggregates, mines, natural gas, oil and groundwater; it forms the basis of agricultural land and fertile soils; Affects our place of residence; enhances the valuable and special landscape around us. In order to assess the perspectives used in geomorphology, in addition to the values of cultural, scientific and economic diversity, also from geodiversity, to provide more reliable data for the protection of the geological heritage. The proposed geopark of West Khorasan Razavi has unique forms and geological heritage dating to the Cretaceous. Therefore, it is essential that the geodiversity is evaluated to list priorities to protect heritage. To do this first, collected required documents and maps and field observations, processed map with GIS software, grided and calculated the diversity of geomorphology, hydrology and geology phenomena in each grid, then, the geodiversity map was prepared in four categories: low, medium, high and very high. The findings of this research show that 9.3% of the area is very high in geodiversity, which is observed in the north and southwest of the region. 11/5% of the area has a high geodiversity that is most seen in the north and west of the region. 37/2 % of the region has moderate geodesy, which can be seen in all areas except the southwest and center. 47.4% of the geodecimal area has a small amount, which are centralized in the central and southeast, where the wind process is dominant geomorphic formation of the region.

Geomorphology is one of the natural factors which has played on outstanding role in establishing settlements, such as Botki hill, in North-west Aleshtar plain. This hill is one the most important settlements Alashtar plain that has a history of about 8000-years old. Therefore, in the present study , considering geomorphology and historical this site, and considering this question have been considered to the geomorphology, The geomorphology features of this site were examintion. , using satellite images, topographic and geological maps, the geomorphological features influencing establishment of this site have been recognized, thus the geomorphological map of this region have been provided with the help of GIS software. Also, by creating trenches the sedimentary properties of site are addressed and described within geomorphological maps. Analysis of the results showed that adequate water and fertile sediments provided a basis for establishment of sustainable settlement,.however geomorphological factors have had a little effects on the site, replacement and destruction. these patterns reflected condditions considering geomorphological features in the establishment of this settlement. Data frome field surveys and satellite images of the region indicate that this region, from the start of its formation so far, have been subjected to a great deal of changes. in a way that, in addition to tectonic movments, external forces interactions affected the region. These factors in turn had an influence on formation and development of water resources and alluvial systems. According to the investigation of alluvial sections, alluviums with different thickness and grading have been shown. Therefore, from stratigraphy of these sections we can elicit that low and high-energy streams impacted the surface alternatively. Also, on the grounds that a vast part of Aleshtar area is confined with Limestone Mountains and suitable Karst systems and the amount of rain and water fall is also in good conditions, such characteristics lead to the formation of rich water sources in this area. So, enriched sources of water and fertile soil have provided a situation for formation of settlement from a very long time ago.

Watersheds are considered as the main unit of planning for sustainable development in many management issues. Evaluating the ecological capability of watersheds and their ranking according to different ecological criteria for prioritizing water management operations is one of the important issues in watershed planning and management. In this study, the Fuzzy-TOPSIS integration method, was chosen to be usen in the Mokhtaran watershed. In this work, 13 environmental criteria, including water resources quantity, flood intensity, soil conservation, surface water quality, groundwater quality, forage production, potential evapotranspiration, groundwater quantity, upstream resources, vegetation composition, water erosion, wind erosion, grazing capacity and groundwater quality of upstream resources were estimated and used. The study area was divided into three blocks of northern heighlands, southern highlands and plain. Each of them has its own criteria, according to the characteristics and potentials of each block. Then, the criteria of each block were weighted by AHP method and each of the 13 environmental criteria was fuzzified. After the fuzzification of the criteria and the weighting of the criteria of each block, the main problem of each sub-basin was determined according to previous studies in the watershed. Then, accordingly, the sub-basins were grouped in each block. Moreover, based on the Likert spectrum, the relative importance of options (sub-basins) was identified as triangular fuzzy numbers relative to each criterion. Finally, by entering all of the inputs in Fuzzy Topsis Solver 2013, the coefficient of proximity of each sub-basin was estimated and based on the nearest coefficient, the priority map of the watershed management plan for the watershed of Mokhtaran was extracted. According to this map, the sub-basins M8, M13, M15, M16, M21, M22, M25, M26, M28 (in the northern heights of the area), M2, M42, M43, M51 (within the southern heights of the area), M32 , M34, M46, M'13 and M'14 (within the plain of the basin) were considered to be in the highest priority and as critical hydrological units. The sub-basins M4, M5, M'4, M'5 (in northern highlands) and M1 (in the plain) were placed at the lowest priority over the study watershed.

In this study, By studying the synoptic patterns of the lower levels of the atmosphere in the warm period (22 may – 22 sep) of Asia southwest (1996 – 2014), and Using factor analysis and clustering tests and also dynamical equations of convergence / divergence, vorticity and omega; an ridge of eastern winds (Iran ridge) was identified on the Iranian plateau, Which is part of the eastern winds caused by the deployment of India's Monson Trough in South Asia and the expansion of tongue from Ganges to the Asia southwest lowlands. Dynamic conditions of the atmosphere in the eastern part of Iran ridge, A nuclear of the divergence of the lower levels, Provide positive omega and air sinking and flowed eastward toward the west, and as the eastern winds flowing westward. At the same time, the dynamic conditions of the western part of Iran ridge, the nucleus of the convergence of the lower levels, Provide negative omega and climbing air that the flow of the mentioned wind pours into it. Then the air climbed in the western part of Iran ridge at the middle level, creates a core of high levels divergence and It flows to the west. With the arrival of this wind on the eastern half of Iran ridge, a core of higher levels convergence has created and with its descent into the lower levels divergence core in the eastern part of Iran ridge, Complete your cycle (Khorasan-Caspian Cycle). At the middle levels, there are also languages from Azores high on the region, the curvature of the northern part forms the ridge of western winds in northe of Iran and the Caspian Sea. The dynamic conditions of the west and east of this ridge caused the formation of negative core and positive omega that this, in turn, enhances the Khorasan-Caspian cycle.

Today, achieving sustainable development and proper and sustainable construction density in the cities to improve the quality of life and improve the urban environment is considered as a necessity of urban development. The increasing urban population growth, resource constraints and the rational efficiency of existing facilities increase the importance of paying attention to the density of urban areas. Since demographic and construction densification is one of the most important means of urban planning in order to balance and create order in a complex urban system. Accordingly, the need for a deep and deep view of the topic of urban density and its effects on other urban phenomena is felt more than ever.The present research is analytical-descriptive. In order to collect information for the study of construction density, statistical blocks of 2011 were used. 384 questionnaires were also used to assess the sustainability of urban neighborhoods. In this study, various statistical methods including Kruskal Wallis and binomial test were used. The results of the research showed that there is a significant difference between the groups of construction density and the level of neighborhood stability in the cities of Babolsar is not equal in terms of density. In fact, it can be stated that there is a significant difference between neighborhoods with different construction densities in terms of physical, environmental and economic sustainability. Neighborhoods with average building density in terms of physical, environmental and economic sustainability are better than low-density (construction) and high-density (construction) neighboroods. However, in terms of socio-cultural sustainability between neighborhoods with different construction densities, there is no significant difference and the situation of this aspect of sustainability is not related to the density of construction in the neighborhoods. In general, Babolsar is not in a good position in terms of sustainability.

Abtract: Today, management and conservation of historical textures have become an urgent and challenging issue. Because many actors play a role in managing the historical texture of metropolitan cities. Therefore, the coordination of these actors and the coherent management of the historical texture are of particular importance. Accordingly, the present study seeks to identify actors and rank them in the historical texture management system of the Shiraz Metropolitan Area in order to assess and analyze the realm of integrated management in the historical texture by recognizing the existing challenges. In this research, based on theoretical foundations, various indicators of urban management in the areas of planning, policy making, legislation, etc., and in the form of a questionnaire of experts (20 samples), were ranked by various actors of urban management using the Delphi model and Weighing is done in the Super Decision software using the ANP model. The results of this research show that due to centralized management of the historical texture, national and state institutions play the most role in policy making and planning of historical texture. Also, local management organizations such as the municipality and city council operate more than supervisory, service and development agencies than they have a managerial role. The above managerial gap has led to the loss of local capital and the reluctance of the private sector and citizens to participate. Therefore, the application of integrated urban management approach in the historical context of Shiraz city is an inevitable necessity, which can reduce the functional divisions governing the management system and improve its performance.

Social Security is one of the criteria is very important in urban life and somehow one of the main needs of cities for the life of its citizens. Usually, in urban environments, physical factors play the most role in increasing or reducing self-esteem.Hence, the purpose of this study was to investigate the effect of physical and environmental standards on social security in urban neighborhoods trying to Improve and enhance the level of social security in urban neighborhoods is a positive step in order to achieve a high level of urban security. The type of applied research and descriptive - analytical method. The sample size for two selected neighborhoods of Rokni and Khezr as the neighborhoods were identified by using Arc GIS software and Hot Spot and Cold Spot maps of Hamedan, respectively (245 and 345) using the formula Cochran was obtained. The sample size is calculated by residents of these two neighborhoods in Hamedan. The sampling method is also simple random. SPSS software was used for statistical analysis. One-sample analysis of variance (ANOVA) and multiple regression analysis (HMR) was used. The main question of this research is that which criteria for physical impact on social security more residents and citizens. The results of this study show that the type of structure and organization of urban communities and, most importantly, the permeability of urban neighborhoods in reducing urban crime and increasing social security has a great effect. For this reason, the suggestion of this study is to provide solutions in general, increasing environmental monitoring and ultimately leads to the promotion of social security in urban neighborhoods.

Since urban areas are urban component to the disorder and the absence of security in the city, so the qualitative and quantitative analysis of the aspects of security, both physically and socially, in urban areas is essential. This study aims to analyze the crime and delinquency in the cities of Fars province with multi-criteria decision-making methods of TOPSIS and SAW. This research method is analytical and practical approach to the study of the data Statistical Yearbook 1392 is used as well as for data analysis and statistical software EXCEL is used. The results using TOPSIS technique suggest that the city of Shiraz with a score of (1) is the most insecure areas of crime and Sarvestan city with a score of (0.005) as the lowest crime rate in the province. Results using the SAW technique also represent the highest crime rate in the city of Shiraz (0.544) and the lowest crime rate in the city Sarvestan with (0.003). Moreover, the city of Shiraz has had the worst status over the last few years that is becoming more complex due to immigration that took place in the city.Results using the SAW technique also represent the highest crime rate in the city of Shiraz (0.544) and the lowest crime rate in the city Sarvestan with (0.003).

Shorelines are very dynamic geomorphic systems where continuous changes occur at differents spatial and temporal scales .Coastal sustainable management, need to know the trend of sea level changes, showing of shoreline changes can ensure coastal relative sustainable for performing plan coastal environmental management. Case study is shoreline of Karkanrod estuary that is located in the west of Gilan between eastern longitudes 48°-34ʹ to 48°-58ʹ and northern latitudes 37°- 42ʹ to 37°-57ʹ.The aim of this research is to extract shorelines from past to now, determine effective land and hydrodynamic processes in the morphologic changes of Karkanrod delta shoreline to assess the rate of shoreline changes and their reasons. Waves and wind data, hydrodynamic data such as sediment and water, sea level fluctuations ancient graphs, Landsat satellite images, Aerial photos were utilized to study shoreline changes that show progress and regress of karkanrod delta. The method used in this research, is a combinational of, descriptive and analytic method with field and library studies.In field observation, some Geomorphologic evidence in the study area such as: V-shaped valleys, fluvial terraces and loesses were identified, that rectify the effect of active tectonics and sea level changes in the region. DSAS method was used to extract shoreline changes in different times.The results of this study show that the shoreline of Karkanrod delta experienced the most erosion during 1985-2000 and the most accretion during 2008-2017. Relative sea level change plays an important role in the shoreline of karkanrod delta. Transects of 7, 8 and 9 that are almost in the center of delta, where the karakanrod estuary is located, have more accretion rate that it shows the effect of sediment rivers. The results and methods may be helpful in coastal management and understanding the evolution of the entire delta from the perspective of shoreline change.
