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 Links Nodes
West Campus SWMM Model 692 Nodes 806 Links 1 Storage Unit (~73,500 cubic meters)
SWMM Steps: • Import original file • Change dates • RUN • Create tool to run data
Results: SWMM Event 16: 4.8 inches over ~24 hours
Event 71: 6.5 inches over ~10 hours Present Detention Pond
Future Work • SWMM- fix HMS inputs • HFR • Small Literature Review
