Infiltration vs. Surface Water Discharge: Guidance for Stormwater Managers (Phase 1)

As stormwater managers seek to protect surface and ground waters from the impacts of polluted urban runoff, it is imperative to select the correct options for the desired goals and to understand the appropriate applications and restrictions of the different methods available for use. The older models often rely upon hand calculations and have many restrictions. Computer methods allow for the use of continuous simulation, but again, limitations exist, and in the case of a computer model, these restrictions are often not as obvious. This report focuses on the development of an overall strategy for selecting appropriate BMPs, and once selected, for selecting appropriate tools to design those BMPs. The report has a specific focus on the appropriateness of, sizing of, and prediction of the performance of infiltration devices. Published by WERF. 260 pages. Online PDF only.
