HFR Method for Large Storm Events Katie Rose Surface Water Term Project
Storm Water Management Model (SWMM) Rainfall-Runoff simulation model – Time-varying rainfall – Evaporation/infiltration – Spatial variability Hydraulic Model – Route runoff through drainage system network – Unsteady flow
SWMM Interface
West Campus SWMM Model 692 Nodes 806 Links 1 Storage Unit (~73,500 cubic meters)
SWMM Steps: Import original file Change dates Create tool to run data RUN
