HEC-RAS
HEC-RAS is designed to perform one and two-dimensional hydraulic calculations for a full network of natural and constructed channels.
SRH
SRH—1D、2D is designed to analyze mobile-bed transport, hydraulic routing, soft bedrock erosion, riverbank erosion, and reservoir turbidity current etc.
FlO-2D
The FLO-2D model was conceptualized in 1986 to predict mudflow hydraulics. The US Federal Emergency Management Agency (FEMA) supported the initial model development and first application to Telluride, Colorado in 1988. What sets FLO-2D apart from other hydrologic and hydraulic models is its capability to simulate urban flooding in high resolution and unlimited detail including the storm drain system.
