"description": "<p>Soil erosion is a process of detachment/dispatch/ of soil particles due to rain drop and<br>\nrunoff. This results deposition of sediment causing reduced flood carrying capacity affects<br>\nwater qualify instability of structure and natural streambeds and banks. For accurate and<br>\neasy estimation of runoff and sediment yield, it can be done by using physical based<br>\ncontinuous hydrological model. Among the many hydrological model Soil and Water<br>\nAssessment Tool (SWAT) is the more promising model for simulations in predominant<br>\nagricultural watershed. Moreover, the model is better in assessing both spatial and<br>\ntemporal variability of the hydrological process under both small and very large<br>\nwatershed. This study is about the estimation of sediment yield and reduction of sediment<br>\nyield with appropriate mitigation measures. The input data for the model were obtained<br>\nfrom different organizations; After the input data are organized and assembled it was used<br>\nfor model simulation. Later simulation result was calibrated and validated using<br>\nCalibration Uncertainty Procedure (SWAT-CUP). The efficiency evaluation criteria’s<br>\nCoefficient of determination (R2), and the Nash-Sutcliffe simulation efficiency (ENS) were<br>\nused for performance evaluation of the model. The result from the calibration and<br>\nvalidation of both flow and sediment were greater than 0.7; this indicated that there was<br>\nvery good agreement between observed and simulated outputs. The stream flow and<br>\nsediment yield of soke watershed was quantified</p>",
