Sediment yield estimation using GIS
A method has been developed in the present study for the determination of the sediment yield from a catchment using a GIS. The method involves spatial disaggregation of the catchment into cells having uniform soil erosion characteristics. The surface erosion from each of the discretized cells is routed to the catchment outlet using the concept of sediment delivery ratio, which is defined as a f...
متن کاملEstimation of temporal variation of sediment yield using GIS
A GIS-based method is proposed for computation of temporal variation of sediment yield during isolated storm events. Data from three Indian catchments, namely Karso and Nagwa in Jharkhand and Kharkari in Rajasthan, have been used. The Integrated Land and Water Information System (ILW1S) GIS package was used for (a) catchment discretization into cell areas using grid networks, (b) evaluation 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...
متن کاملEstimation of erosion and sediment yield of Ekbatan Dam drainage basin with EPM, using GIS
Soil conservation and control of erosion is a basic problem in all countries. The goal of this research is to estimate erosion and sediment yield in Ekbatan Dam drainage basin by Erosion Potential Method (EPM), using Geographic Information System (GIS). The basin is located in Hamedan Province, west of Iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. The study ar...
متن کاملEstimation of erosin and sediment yield with EPM model in Zemkan basin using GIS
The goal of this study is determination of erosion rate and sediment production and exploring sensitive areas of erosion in Zemkan basin, located in the West of Kermanshah Province.To achieve these objectives, the erosion potential method (EPM) was used.Geographical information system also was used to reduce the errors and increase the relative accuracy in the analysis of the model. Required da...
