Simulating Head Losses in Hydraulic Drop Structures in SWMM, with a Little Help from CFD

A modeling study was undertaken by Peter Klaver and Jason Rutyna, from LimnoTech, David Collins from David J. Collins Engineering, and Kurt Robinson, from the City of Portland, to better understand flows and losses in hydraulic drop structures. A conceptual approach to representing the head losses in vortex structure generators within a SWMM-based modeling framework was developed, and the general applicability of the approach was tested through a series of CFD model simulations.
