Data for modeling soil erosion with evolving rills on hillslopes
Whereas current erosion models can make quantitative estimates of soil erosion by water flow with much success, modeling the coevolution of geomorphological features, particularly rill network properties, and soil erosion on hillslope is still a main challenge. In this study, we propose a rill evolution modeling approach and combine it with a rainfall-runoff and soil erosion model to simulate the feedback loop of hillslope geomorphic development and soil erosion processes. The dataset included the simulation results of model calibration and validation (see the excel files of Figures 3-5), the effects of rainfall intensity and slope angle on rill evolution (see the excel files of Figures 6 and 7), and the sensitivity analysis of the rill evolution parameters (see the excel files of Figure 8). There is a one-to-one correspondence between the data file and the figure in the present paper so that we can easily understand and use the data.
