Water is life  resource  for living creatures especially  human  being .Water is the first and necessary toop for industrial development the base for agricultural production .if the mater of water and soil conservation be considered systematically and in the wide spread scale, in fact the consistency of natural environment is fulfilled (rajaei 1382).The resource area is located between 50 35 to 26 36 of north  latitude and 12 54 to 46 54 north longitude which reaches from north to alborz mountain frome east to moladeh village, from west to damghan city and from sout to hajaligholi playa . in this area the following villages are located , mehmandoost, dehmolla, kalatimolla, forat,zarrinabadmehdiabad,abbasabadT,vamerzan,bagh,jazan,heidarabad and haji abad which contain a population about 62000 person including damghancity. the main occupation of population of this region is gardening. The disaster of underground water table falling , Stalinization of water, increase of demand and region potential for increasing cultivating lands needs a full study for providing sustainable situation and is one of the most necessary need of the ragion. In order to reach to this aim all geographical, natural and especially geomorphology agents of region were strictly and in the field , using GIS hardware were studied to find the role of them on water resources of this area where is one of the centers of human activities in the field of agriculture . the results show that the geomorphology of the region including tall mountains, affecting on the amount of rainfall, also tectonized limestone formation, have an important role on water provision of the region, which with wide plainheads have the principle role oo feeding underground tables.

Sustainable urban development is a tool for controlling and directing city development and activities and promoting the city's environmental qualities. The use of sustainable urban development approach provides opportunities for the creation of applied geographic systems through which these systems can integrate natural processes, urban environments and human activities. Reviews of this article Develop the city of Torbat Heydarieh with The emphasis on the intrusion of the fault in relation to the extent of the vulnerability contribution of different indicators in different dimensions of development. The method of this research is descriptive-analytic based on the library collection method and analysis based on the method of weighting and selection of criteria using AHP technique. In this research, 12 criteria for selecting the sustainable urban development index of Torbat-e-Heydarieh with emphasis on the role of Duroneh fault in the dimensions of physical, geomorphologic and environmental aspects were considered. Then, these factors were weighed. The results of the research show that in total With a range of different areas, a significant percentage of the city's various districts and districts are vulnerable, with a view to reducing potential risks, appropriate planning should take place in these neighborhoods

The old texture of most cities over time and due to new developments has lost its past performance and gradually declining, and nowadays, as the largest ancient texture of most cities, over time and due to new developments, its past performance Lost and gradually disappeared and today they are considered as the biggest problem in the cities. In this regard, the present study seeks to revive the worn out urban landscape in order to achieve sustainable urban development indicators. The method used in this research is descriptive-analytical and information is collected in two ways through library and field studies (interview and observation). The statistical population of this study is the population of the worn out tissue with a population of 13,241 people In this research, the economic, social, physical and environmental characteristics of the study area as well as the physical problems and problems of residents of the tissue have been investigated, which also includes a major part of the problems of attendance. Of course, the 84% share of owners in this context, as compared to the whole city, which has a large share of endowment lands, has provided the conditions for a better account of the factors of corroded tissue regeneration with sustainable development considerations. Finally, based on SWOT analysis and Geographic Information System (GIS), data analysis has been used. In this research, it has been tried based on the findings, general, legal and executive suggestions based on indicators of sustainable development focused on targeted participation .

Geo tourism is one of the industries that has many revenues and revenues for societies. Following the transformation of demand in the 90s and the 21st century, other forms of tourism replaced the traditional mass tourism. The land of tourism or geo tourism is one of those forms that focuses on the understanding of forms and geological processes. Considering this part of tourism due to the competitiveness of tourism destinations is increasing day by day. The city of Dehloran in the province of Ilam is one of the destinations for the unique geo site alled the bog cave, spa springs and bitumen springs. Their special position distinguishes Dehloran from other similar purposes. The emphasis of this paper is on the proximity of these geo site together in the form of a triangle and the study of the distances and capabilities of this advantage. This study is an applied objective and has tried to analyze the capabilities of the tourism egoists in this city with a descriptive-analytical approach. The information it needs for analysis, from up-to-date and specialized resources, as well as official websites. The findings show that investing in these attractions is justifiable and has a very strong potential for attracting tourists and specialists, given the close distances and geostationary distances. Finally, by considering the results of the research and considering the geographical location of the region, constructive suggestions are made for the development of geotourism in the province of Ilam..

As the biggest metropolis of Iran, Tehran is among the most polluted cities of the world. Due to the detrimental effects of air pollution on health and environment, determining the exact pollutant and areas of pollution is necessary. The aim of this study was to investigate the ability of MODIS data. This study measure particulate matter (particle pollution) in urban areas and make air quality maps using these data and the ground data. Data related to the pollutants pm10, o3, co, so2,pm2.5 in 1394 using simple kriging method as a method of  ground statistics in different modes were evaluated and maps of pollutants levels were drawn. In addition, satellite images of the first level and second level data of this sensor for qualitative and quantitative analysis of particulate matter was used in large areas. Then, using the Normalized Difference dust Index (NDDI) related to the first level data and parameters such as optical depth and Angstrom view related to the second level data, their correlation and RMSE with ground data related to the pollutant PM10was calculated. Results indicate that there was proper correlation between satellite images parameters and ground measurements. Discussion and This correlation indicates the images ability of this sensor to detect atmospheric dust. Also, in this study the role of meteorological parameters influencing air pollution was investigated and results indicate that the dominant pollutant index in the year94, was the particulate matter pm2—.5and PM10.Continuous stability of weather condition is among the effective factors that increase the density of pollutants that leads to the pollutants accumulation.

Cities are considered to be one of the most sensitive geographical areas due to demographic changes and land use, which, if these changes are not explored and foreseen by the authorities and municipalities, will cause irreparable financial and human damages to the citizens. The lack of planning in the field of urban development and determining the proper direction of growth of the city today has caused irreparable losses and costs, such as the expansion of cities such as Neishabur on the territory of Qanat. Ghannat is one of the oldest and most economical methods for extracting groundwater and is part of Iran's national heritage. But today, with the underground water level and the drying of the aqueducts, these underground channels have become a crisis in urban areas. Dozens of buildings are damaged in Iran annually due to its collapse caused by the canals of the Qanats. The present paper uses a field-analytical method and using documentary studies, using the AHP hierarchical process model and GIS software using various indicators and valuation of land subsidence criteria to study the areas at risk in Neyshabour city. Finally, there are also strategies and policies to prevent, plan and manage crisis management in the event of a risk.
