HFR Method for Large Storm Events
Katie RoseSurface 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 Nodes806 Links1 Storage Unit (~73,500 cubic meters)
SWMM Steps:
Import original file Change dates
Create tool to run data
RUN
SWMM Automation: MATLAB
