A study is being conducted on the development of a microcomputer model for simulating storm sewer flow under surcharged or pressurized conditions. Several existing models, including the EPA Storm Water Management Hodel (SYMM) and the Illinois Urban Drainage Simulation (ILLUDAS), have been reviewed. It was concluded that the SVMM program's EXTRAN subroutine, which uses a full dynamic wave approach, would be suitable for our purposes. Certain modifications of EXTRAN will be necessary, and the modified subroutine will be incorporated into the Federal Highway Administration's Pooled Fund Storm Sewer Program PFP-HYDRA.
