Geographic information system and process-based modeling of soil erosion and sediment yield in agricultural watershed
BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...
متن کاملSoil surface roughness quantification using DEM obtained from UAV photogrammetry
The soil surface roughness is one of the most susceptible to variation in time and space characteristic, and depends on many variables like cultivation practices or soil aggregation. Various indices are used for its quantification, in microscale soil roughness is commonly expressed by HSD calculated from DEM of small sample area. The source of DEM can be close range photogramethry or laser scan...
متن کاملApplication of Gully and Rill Erosion Indicators for Estimating Soil Loss Using GIS Techniques
The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion andsediment estimation one can use statistical and empirical methods. For doing this, land unit map and the map of effectivefactors should be prepared. For erosion and sediment estimation one can use statistical and empirical methods. However,these empirical methods are usually time co...
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 Stormwise Sediment Yield of Gully Erosion Using Important Rainfall Components in Different Land Uses of Zagros Forest, Iran
Erosion is one of the important social-economic problems in Iraniancatchments that have been posed by surface water vastness and runoff production. So, thestudy of water resources, soil erosion and effective factors is of high importance. Gullyerosion also extends in many parts of Iran and its study particularly in viewpoint ofsediment yield is therefore very important and should be taken into ...
