Suitability of HEC-RAS for Flood Forecasting [PDF]

open access: yesCanadian Water Resources Journal, 2005
At present, most river flood forecasts are conducted using a two-step procedure. First, flood routing is conducted, normally using hydrological models. The resulting flood peaks are then converted to water level forecasts using a steady flow hydraulic model, such as HEC-RAS.
