1. HFR Method for Large Storm Events Katie Rose Surface Water Term Project

2. 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

3. SWMM Interface

4. West Campus SWMM Model 692 Nodes 806 Links 1 Storage Unit (~73,500 cubic meters)

5. SWMM Steps:  Import original file  Change dates  Create tool to run data  RUN

6. SWMM Automation: MATLAB

7. Hydrologic Footprint Residence (HFR)
