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.

The purpose of this study is zonation of landslide in Kerman province with Fuzzy and AHP models. In this study in order to obtain hazard zonation map, 7 factors were studied. This factors in GIS software were mapped and then classified and weighted. These maps were overlapped with the landslide distribution map,until the role of landslides distribution to be determined. Finally, the 7 factors including slope, Seismicity, lithology, Drainage density, Morphology, Precipitation, Land use were identified as factors influencing in landslides the basin. The maps the landslide hazard zonation was prepared based on these 7 factors and the methods of AHP and Fuzzy Gamma operator 0.7, 0.8 and 0.9 in GIS. Also the index of Quality sum (Qs) were used for evaluation of the accuracy of zonation maps. The results of the evaluation of the maps showed that the amount the indices Qs for AHP model is equal to 2.31 and for Fuzzy Gamma operator, it would be 0.7, 0.8 and 0.9 respectively 4.05,1.85,3.27. Therefore, it is concluded that the operator the Fuzzy gamma would be 0.7 compared to other methods. So it is better for utilization in the landslide hazard zonation in in Kerman province Manuscript profile

Macro scale parameters (e.g. Land use, population density, geology and erosion etc.) have been considered as macro scale indicators (MSIs) to estimate the water quality in river. The effects of MSIs on water quality variables (that here in after call as micro scale variables / MSVs) were investigated through multivariate statistical analysis (MVA). Several MVA employed to find out, validation and verification of interaction effects in screening steep wise stages. The analysis was applied to in situ and laboratory measured data. The sampling process had been carried out on 15 stations, in three stages, in Siminehrood River. The Siminehrood River is located in north-west of Iran as one of important rivers which is terminated to Uremia Lake. MSVs includes all NSF variables. Results demonstrated the high resolution interaction between MSPs and MSVs. the results declared a dramatic relation between dry‌ farming/irrigated farming and PO4,TDS and Turbidity. Urban land use and first level erosion we considered as effective MSPs on BOD5, EC and TDS. High ranked pollution category of geological layer is detected as one of effective MSPs on PO4 and physical water quality variables. The results led the research to the MSPs estimating river water quality in comparative water quality studies in different river basins. Manuscript profile

Dam are one of the most important structures that regulate surface currents, especially in areas that have a place and inappropriate distribution of precipitation. The benefits of dams can be urban and agricultural water supply, electric energy production and prevent flooding. Construction of dams causes major changes the river around and catchment basin. The most important of these changes is the change in the river flow downstream.  Because Dubai of the natural state become regulatory state. One the positive effects flood control, but in areas that are agricultural, reduce Water River and negative effects is on the section. Construction Safa dam cause negative impacts on downstream areas, the city of Jiroft and wetlands is Jazmurian. Assess the environmental impact of the dam Safaroud the city of Jiroft of the way Check list of was used. Manuscript profile

In order to understand, interpret and evaluation of soil and water contamination of any region, having information about geological conditions is essential. The study area (Sefid rud basin) is located in Gilan province. To investigate the source and parameters that affect arsenic concentrations in the Sefid rud basin, 336 samples from 48 stations (over 9 month) and chemical analysis (61 rock samples and 18 sediment samples) were analyzed. Results showed that As levels in some parts of the study area is exceeds the standard limit. Based on calculation of concentration ratio, the measured elements in most samples had a higher concentration than the Clark value, which indicates rock unites had a great potential impact of contamination on the Sefid Rud basin. Hydrogeochemical parameters of surface and ground waters as well as mineral assemblage and sedimentological characteristics were examined. The highest levels of arsenic contamination were observed in Fakhrabad and Salekdeh wells during October and November. Measured correlation coefficients showed that Nitrate and DO values have negative correlation with arsenic concentration of surface and ground waters. Hydrogeochemical information indicated arsenic release into surface and ground waters of study area is controlled by complicated processes which includes: 1. Arsenic dissolution from Fe oxy-hydroxides as the main process 2. Decomposition and weathering of rocks and minerals of the study area 3.Mineralogical composition of the aquifer 4. Intrusion of seawater and increased salinity 5. Human activities.   Manuscript profile

Reducing the quality of ground water in arid and semi-arid southern regions of Iran, most of the pollution is geogenic source and human source. Among the many harmful contaminants, nitrate and fluoride contamination are more spread. In this study, in order to evaluate fluoride and nitrate concentrations and compare the results with national and international standards, health risk assessment was conducted in non-cancer diseases in the aquifer of Lar. In this study, more than 17 wells in two wet seasons (May) and the dry season (September) were sampled. Selected wells used primarily for agriculture. Anions values, Cl, and Cations Ca, K, Na, Mg, using APHA were analyzed in the laboratory. The human health risk assessment using indicators Environmental Protection Agency (EPA) was measured. The average concentration of fluoride and nitrate in the wet season F=2.9 NO3=19.7 and the dry season F=1.8 and NO3 = 16.3ppm, respectively. Risk factor (HQ) and CRlim (maximum water) was calculated for the elements fluorine and nitrate. The results show that the measured concentration for nitrate and fluoride elements in some samples taken over the limit set by the World Health Organization (WHO) for drinking water and hence the aquifer for domestic water use for people and especially the reported amounts of fluorine is dangerous for children Manuscript profile
