- Abstract:
- With respect to the prob lem of serious rainstorm erosion of multi-level terraces in Majiagou river basin from June to September in 2013, this article used the WEPP model to simulate the soil erosion of rainstorm of multi-level terraces, and then compared the result of simulation with the observed data. The results show that WEPP model can well simulate the runoff and soil loss of multi-level terraces under rainstorm in Loess Hilly and Gully Region. With the increase of terrace level the precision of WEPP model of the simulation on runoff and soil loss reduced; simulation of runoff is less than the result calculated by runoff coefficient method due to the influence of the groundwater. Simulation of soil erosion is greater than the measured erosion as a whole because of the prevention erosion of the terrace ridge. This research result provided scientific basis and effective method for the terrace anticorrosive and terraces buildup and provided scientific basis for the forecast of multi-level terrace erosion under rainstorm in the loess hilly region.
