Pressurized Storm Sewer Simulation: Model Enhancement

Report No: 91-R11

Published in 1991

About the report:

A modified Pressurized Flow Simulation Model, PFSM, was developed and attached to the Federal Highway Administration, FHWA, Pool Funded PFP-HYDRA Package. Four hydrograph options are available for simulating inflow to a sewer system under surcharge or pressurized conditions. Several key parameters, such as time-step and print options, are discussed on a theoretical basis for the development of guidelines recommended for parameter selection. A User's Manual for PFSII was completed, providing detailed instructions on the use of the model.
