This paper presents a method to simulate hydraulic erosion and sedimentation on a terrain represented by a triangular mesh in realtime. Our method achieves interactive performances by dynamically displacing vertices using CUDA following physically-inspired principles; the mesh is generated in a preprocessing step to avoid degenerated cases in highly deformed areas.
