Comparing Efficiency of Hill Slope Erosion Model (HEM) in Dry and Abandoned Land (Case Study: Khosbijan Research Center, Arak
Soil erosion and sediment yield from watersheds confine sustainable use of land resources and is supposed as one of the most critical environmental issues. Prediction of storm wise soil erosion and sediment yield is very important, especially in arid and semiarid regions due to small number of events and high intensity of rainfall. Evaluation of soil erosion by existing models is needed as an i...
متن کاملRunoff and sediment yield modeling using WEPP in a semi-arid environment (Case study: Orazan Watershed)
Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...
متن کاملstorm-wise sediment production of gully erosion in the west of iran
different types of soil erosion including gully erosion occur in many parts of iran. the west of iran is further threatened by gully erosion due to its specific physical and climatic conditions. however, few studies have been carried out to study the sediment production of gully erosion in iran. this research was therefore conducted to measure storm-wise sediment production of gully erosion in ...
متن کاملcapability of hillslope version of wepp model in prediction of runoff and soil erosion dynamic in different type of semi-arid rangeland
the wepp physically model is able to dynamically simulate runoff and soil erosion using physical concepts of erosion and hydraulic of overland flow science considering plant growth, residue decomposition, winter process. determination of the capability of this model in runoff and erosion estimation in different range type with investigation the effects of management were the main objectives of ...
متن کاملEstimation of soil erosion and sediment yield using GIS
A Geographical Information System (GIS) based method is proposed and demonstrated for the identification of sediment source areas and the prediction of storm sediment yield from catchments. Data from the Nagwa and Karso catchments in Bihar (India) have been used. The Integrated Land and Water Information System (ILWIS) GIS package has been used for carrying out geographic analyses. An Earth Res...
