River & Sabo

We model and analyze all kinds of water and sediment transport processes such as flow, sediment runoff, riverbed evolution, sedimentation in dam reservoirs, and debris flow in order to understand various problems related to rivers, erosion control, and dam reservoirs, and to study countermeasures and planning.
