Today, as the focus of watershed planning and management for sustainable development in many of the issues. Ecological watersheds can be evaluated and ranked them according to various ecological criteria for the watershed, one of the important steps in the planning and management of watersheds. Since the cost of watershed management projects and heavy construction project budget is limited, it ...
There is a multifaceted approach of water resource in a watershed, which is accompanied by complexity and issues such as the interaction of natural and human systems. Achieving the consistent governance of water resources is one of the most important management approaches in the water sector, which requires a coherent structure of knowledge transfer and information on the organizations stakehol...
overgrazing and inappropriate use of taleghan rangelands has led to poor and very poor condition for almost all vegetation types. taking the importance of rangelands in forage production and other benefits into consideration, management of these rangelands and improving their condition seems essential. the present research was conducted using data integration of vegetation, condition, slope, so...
the use of gis tools is one of the newest methods for performance of different land evaluation and planning projects. this research with the purpose of determination of appropriate landuse to natural land potential and improvement of land management of catchments was executed using gis-tools in taleghan area. at first ecological and socio-economic resources determined, mapped and entered to gis...
Substantial population growth and urbanization arbitrarily banning the exploitation of natural resources and environmental factors adversely impacts the environment and resources necessary for nutrition and healthy life styles. The secret to success and survival of ecosystems depends on a stable, continuous monitoring of the environment. The SWOT model has been developedto consider all int...
Calibration of model is critical for hydrologic modeling of large watersheds in a mountain watershed. In this study Soil and Water Assessment Tool (SWAT) used to comparison a single-site calibration procedure that employed streamflow measurement at outlet of watershed to a multi-site calibration method that used streamflow measurements at three stations (Galinak, Joestan and Dehdar). Results sh...
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...
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...
