A new approach for simulating water erosion on hillslopes
Abstract:Based on existing modelling theory and the visualization methodology of water erosion on hillslopes, this paper classifies models of overland flow and erosion as formal logic computational models and dialectical computational models, e.g. RSIMWEH (Remote Sensing Information Model of Water Erosion on Hillslopes). During the process of combining the latest technologies (particle systems and metaballs, which are based on the field of computer graphics) with RSIMWEH, we put forward the conception of erosion voxel, which is governed by the laws of geography. Using our method, we have successfully simulated irregular dynamic fuzzy objects and the erosion-voxel-based process of water erosion on hillslopes in 3D space.
