- Abstract:
- The soil and water assessment tool (SWAT) is a physically based continuous event hydrologic model. This study carried out SWAT model to simulate the runoff with the measured data collected from Luoyugou watershed from 1986 to 2000. Based on the sensitivity analysis, the main parameters such as CN2 affecting the simulated values in the watershed were detected. The parameters were adjusted based on the above analyzed results. From the results of calibration, the relative simulated error was less than 14%; the relative coefficient and Nash-Suttcliffe coefficient were 96.1% and 0.89, respectively; and from the results of validation, the relative error was less than 8.8%, the relative coefficient and Nash-Suttcliffe coefficient were 91.5% and 0.82, respectively, which indicated that the model can simulate the runoff outputs in the study area with satisfaction.
