  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 Links Nodes

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

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

  6. SWMM Automation: MATLAB

  7. Hydrologic Footprint Residence (HFR)

  8. Hydrologic Footprint Residence (HFR)

  9. HFR Results

  10. Results: SWMM Event 16: 4.8 inches over ~24 hours

  11. Event 71: 6.5 inches over ~10 hours Present Detention Pond

  12. Future Work • SWMM- fix HMS inputs • HFR • Small Literature Review
