  Waste disposal site selection is a critical issue in the urban planning process because of its enormous impact on the economy, ecology, and the environmental health of the region. Waste disposal site selection process aims to locate the areas that will minimize hazards to the environment and public health. The purpose of this study was to determine suitable waste disposal site selection by using the geographical information system and the analytic hierarchy process (AHP) in the study area. In this study first, with using related equations was calculated adequate area to burial chghabale solid waste for 20 years then by using of many data layers such as lithology, land use, soil, road, groundwater and … by using GIS and AHP model was attempted to choice the best location for burial waste of chghabale. According to the results obtained from the map for the site selection of landfill, 15.36%, 20.34%, 27.56%, 29.08% and 7.62% of the site area are located in the very unsuitable, unsuitable, moderate, suitable and the best suitable area, respectively.

  Groundwater is one of the most important of water sources for human life. Because of limitation of surface water sources of several regions of Iran, groundwater can be considered as the most appropriate sources for supplying these regions. Currently, Remote Sensing and GIS are considered as one of the most powerful and affordable tools for exploration of groundwater. Talents of this study are identification of high potential regions of the Romeshgan plain using by AHP‌Fuzzy, Remote Sensing techniques and GIS. Based The lithological, thick alluvium, landuse, elevation, slope, drainage density, fault density, temperature and rainfall layers were prepared using Fuzzy method in GIS environment and based on geological, hydrological, structural, topographical data, satellite images ETM+ and field visit. These maps were weighted using pair comparison in AHP method. The maps of mentioned factors were prepared by applying weights to each criterion and according to their importance in delineation of groundwater potential. Finally, the final maps were provided using the AHP-Fuzzy overlapping approach. Results indicate that about 7.37, 10.12, 22.25, 20.46 and 39.79 percent of study area fall in the areas with very low, low, medium, high, very high for Delineation of groundwater potential.

  The determination of municipal waste landfill is a major issue in the process of urban planning due to the huge impact it has on the economy, ecology and environment of any region. In the process of determining municipal waste landfill, attempt is made to consider sites with minimum risks for the environment and human health as well. This study aimed to have an environmental evaluation and determination of municipal waste landfill in Poldokhtar using Geographic Information System (GIS) and Weighted Linear Combination (WLC). For this purpose, the current landfill was first assessed in terms of the environment. The results of the evaluation show that the biochemical and chemical activities are very high in the desired site. Therefore, paying special attention to the environmental impacts of the current landfill is of great significance. Then, the map for the site selection of Poldokhtar’s landfill was prepared based on investigating and assessing 10 parameters including the distance from city, village, drainage, rainfall, major and minor roads, lithology, landuse, slope and elevation,. According to the results obtained from the map for the site selection of landfill, 11.33%, 20.51%, 25.94%, 22.65% and 19.56% of the site area are located in the very unsuitable, unsuitable, moderate, suitable and the best suitable area, respectively.

  Today, the most important step to control sewage pollutions and reuse of wastewater, is to construct sewage treatment plants and closely monitor their performance.In this research, the aim of this study was to investigate the environmental impacts of sewage treatment effluent in Kermanshah on some physico-chemical parameters of GharasoopermanentRiver so,changes of these parameters were investigated in Gharasooriver water samples at different time intervals.The average of changes in these parameters were compared in dry season with the variation of this parameter in the wet season (November).Investigation of daily changes in acidity of samples in different parts of the wet season (November) of the year 95 illustrate the fact that the processes of neutralizing the acidity of the effluent have an effect on the process of dramatic changes in this parameter and shows a decrease in the acidity in the output samples in respect of input samples.Also, the results of measurement of the biological oxygen demand of samples show that sewage treatment processes have been effective in removing various sludge and various microorganisms.The results of measuring the amount of total suspended solids in water samples indicate effective efficiencies and the proper functioning of the wastewater treatment process.Measuring the temperature of water samples at 3 different points shows that in these 3 points the water temperature was constant and has only shown a slight change at different times. The amount of nitrate in the samples and the amount of dissolved oxygen from the inlet point of the refinery to the outlet point has been increasing. Daily changes in alkalinity and acidity, the amount of biological and chemical oxygen demand and the amount of phosphorus at the inlet point of the refinery to the outlet point and samples from distant distances have a decreasing trend.

  In this study, we tried to dentify the fractures and faults of Khaviz Anticline, north of Behbahan, by using the ETM+ satellite images and the Digital Elevation Model (DEM) in the ENVI 4.8 and Arc GIS software environments. Therefore, the lineaments were identified using the linear filters in different directions and the hillShade map constructed from the DEM. Subsequently, the lineaments were compared with the constructed band combinations and the geological map to separate the fractures and faults. Based on the findings, the dominant direction of the fractures and faults follow the northwest-southeast (NW-SE) trend along Khaviz Anticline. Assessment the ISODENSITY map of the faults and fractures indicates that there is the utmost accumulation of the fault and fractures is in the south limb of Khaviz Anticline, Then by considering the important role of fractures and faults in migration of hydrocarbons, the southern flank of this anticline can acts as a suitable area for accumulation of hydrocarbons Manuscript profile

  Soil erosion is one of the major environmental concerns of the present century. This issue has become a major problem to the environment and natural resources, so that statistics indicate that soil erosion in Iran is several times more than global average. This research was carried out with to investigate the factors affecting the Varak area erosion and its risk zonation using the EPM method. For this purpose, field visits and satellite images studying were used to investigate the erosion. Then, the information layers of the area including average slope, soil and rock susceptibility to erosion, land use and observational erosion were prepared, and information layers were weighted and the erosion risk susceptibility map was prepared. In addition, the results from the risk zonation of the region show that 6.3, 55.2, 26, 3.1 and 9.4 percent of the region are at the erosion risk classes of very low, low, moderate, severe, and very severe, respectively. Based on the zoning, the focus of the erosion-sensitive areas are in the southwest, northwest, and a part of the north of the region, which is consistent with the fossilized and fractured parts of the Asmari lime, which has a higher slope. Considering the field observations, investigating the precision measurement of the method used to prepare the potential erosion risk map of Varak watershed indicates that the EPM method has a fairly high precision.
