today water supply issue in large cities seems to be a big problem. this becomes more important with population growth and urbanization extension. to cope with this problem lots of irrigation and drainage projects have been implemented and operated that subsequently many socio- economic and cultural effects have been brought to the areas . the objective of the present study is to survey the soc...
Reviewing the damage caused by landslide proves the need to examine the factors influencing the occurrence of this phenomenon and the prediction of its occurrence. Therefore, the purpose of this study was to improve the prediction of landslide occurrence in the Taleghan watershed using Shannon Entropy Theory. Among the factors influencing the occurrence of landslide, ten factors of elevation, s...
Taleghan has a suitable ecological condition for growth of diverse plants. There are many species that are used in folk medicine by inhabitants for the treatment of infection diseases but there further information is required. For this study, approximately 200 species were collected and identified at the Herbarium, school of pharmacy, Tehran University of medical sciences (THE). Pre-Phytochemic...

the healthy condition of the taleghan river in upstream of the taleghan dam was studied in order to better understanding the role of benthic invertebrate bio-purification faced to waste water inflows to the river in several parts. sampling was started from the fall of 2005 and continued to the winter of 2006. in this way, five stations were selected using a pre-sampling strategy based on simila...
in recent years, changes in catchments water balance due to land use management have become the main concern of water resources authorities in iran. due to rapid population growth and land use changes, especially construction of taleghan dam, taleghan catchment has undergone rapid changes such as urban development, declining of rangelands, and deterioration of environment and erosion of soil re...
In this study, land use change in the middle Taleghan watershed has been studied and analyzed. First, the land use map of Taleghan Mian watershed was prepared during the last thirty years in four years 1987, 1998, 2008 and 2017. Landsat satellite imagery was used to prepare land use map in four years. In this research, the hybrid classification method (combination of supervized and unsupervized...
Landuse change and climate are the main drivers of hydrological processes. The purpose this study was to analyse separate combined future effects landuse changes on water balance components different spatial temporal scales using integrated Soil Water Assessment Tool model. focused relationship between yield (WYLD) sediment (SYLD) in heterogeneous Taleghan Catchment Iran. For scenarios, RCP 4.5...
