Development and Application of Spatially Distributed Runoff and Sediment Yield Model |
|
| چکیده انگلیسی مقاله |
The present study proposes a distributed digital elevation model (DEM) based runoff and sediment yield model. The model takes DEM as a primary input and determines flow direction, flow accumulation, channel extraction and flow routing sequence for each cell of the DEM. The model calculates the runoff (using the NRCS curve number method) and sediment yield (using MUSLE) on each cell (pixel) of the DEM and routes these hydrological parameters over the overland flow cells into the drainage channels to the watershed outlet using Muskingum routing method. The model develops the runoff hydrograph and sediment graph at the watershed outlet. The backend and frontend of the model is developed in Python and HTML+JavaScript code, respectively. The performance of the developed model (in terms of runoff, sediment yield, peak runoff rate and time to peak) has been evaluated by comparing the model output with the observed runoff and sediment yield measured at the outlet of forest micro-watershed located in Shivalik foot-hills of North-West India. The statistical analysis reveals the reasonably accurate performance of the developed model in simulating runoff and sediment yield as is corroborated by low values of PBIAS, MAPE, MBE and RMSE and high values of correlation coefficient and model efficiency. |
