Simulation of runoff and sediment yield for the calo watershed, Vinh Phuc province by using swat model
Singh, Ravi K. Ghosh, S.K Nguyen, Ngoc Thach Pham, Xuan Canh Smallest watershed is considered to be the ideal unit for management of the water resources in a water basin. Extraction of water-shed parameters using Remote Sensing and Geographical Information System (GIS) and use of mathematical models is the current trend for hydrologic evaluation of watersheds. The Soil and Water Assessment Tool (SWAT) having an interface with ArcView GIS software (AVSWAT2005) was selected for the estimation of runoff and sediment yield from an area of Vinh Phuc province, an intermediate watershed of Ca Lo River, located in Western Tam Dao mountain which cover nearly all region of the Vinh Phuc province . Base on Hydo Response Unit HRU ( as the basin parcel ), the performance of the model was evaluated using statistical and graphical methods to assess the capability of the model in simulating the run-off and sediment yield from the study area. Result of the study are informations on quality a...
