Summary

Hydraulic erosion plays an important role in the formation of landform. Influenced by runoff, soil is destroyed, denuded, and transported to form a specific landform. The simulation of erosion can not only be used for the construction of realistic terrain, but also for evaluation in soil and water conservation, which has important research and application value. We construct a hydraulic erosion simulation framework on the basis of soil and water conservation's theory, which considers various factors in erosion, including: water flow, infiltration, transportation, erosion, ditch widening, deposition, and soil sliding. It is the first time to consider the generation time of runoff, soil fixation of plant roots, and ditch widening phenomenon in simulation. Using this method, we can simulate ditch evolution process from rill, shallow ditch, cut ditch to gully, which consist with the real process. Compared with real photos and data, our method has authenticity in both visual and theoretical aspects.
