A Study of concurrent rainfall-runoff in austin, tx rose marie klee
problem • Tailwater assumptions • Magnitude of concurrent events • Waller Creek Tunnel Project
problem Tailwater Elevation
Background • Available guidance • Waller Creek and Colorado River basins • Areal Reduction Factors
methodology • Obtained Colorado River HMS model from LCRA • Computed ARFs • Used GIS to create/compute circular storm and calculate an aggregate ARF for each subbasin • Used HMS to model multiple storms in the Colorado River Basin • Evaluated results
conclusions • Not the whole story…storms move; hydrograph timing is important. • Further work could include: elliptical storms, different reduction factors, moving storms, inclusion of hydraulic model, analysis of real storms.
