Hydraulic Modeling of Stream Restoration / Wetland Restoration Projects using HEC-RAS Unsteady Flow

An unsteady flow HEC-RAS model was developed for two projects in Annapolis, MD to demonstrate the attenuation of peak flows for stream restoration projects. HEC-HMS was used to calculate a flow hydrograph that was inputted into HEC-RAS to run an unsteady flow model. Storage areas and infiltration were used to approximate the riverine system. The model was optimized based on known water surface elevations and precipitation.
