Assessment of Runoff and Sediment Yield using Routing Model

Abstract

The assessment of runoff from rainfall and sediment yield is essential for management and conservation of water availability and can also apply for several applications of hydrology. The technique of Sediment routing has been evolve to route the sediment yield from a selected area which was divided into five sub-basins at Anakapalli station. Remote Sensing (RS) and Geographic Information Systems (GIS) technique are used to find the parameters and develop the routing model. The data related to factors of Runoff (R), Soil erodibility (K), Topographic (LS), crop management (C) and conservation practice for development of the model. In order to affirm the overall performance of the routing technique for the take a look at area, the release and sediment yield records from the Anakapalli gauging station has been collected for 28 rainfall days January 2020 to October 2020. locate at the records amassed, to compute the sediment yield from Routing technique. Measured sediment yield from selected point has been validated to the routing sediment yield from the selected basin. The effect of sediment yield has been evaluate herewith of calculated data and it is establish that coefficient of resolve (R2) are 0.96 and Efficiency of Nash Sutcliffe (ENS) of 96.19 for Routing model is performing well for the studied basin, it is effectively used for assessment of sediment yield in the selected place
