The Bay Area Hydrology Model (BAHM) is a tool for analyzing the potential hydrograph modification effects of land development projects and sizing structural solutions to mitigate the increased stormwater runoff from these projects. This software was developed for use in three counties in the San Francisco Bay Area: Alameda, San Mateo and Santa Clara.
At this site you'll find links for downloading the BAHM software and User manual, as well as more information about the BAHM and how to use it. For further questions or to join our e-list for announcements and updates, please contact firstname.lastname@example.org
Training Workshops The Basic workshop is a four-hour introduction to the BAHM, including review of technical features, walk-through of the BAHM design process and discussion of basic examples. Attendees should have basic knowledge of hydrology as well as hydromodification management concepts and how they fit into stormwater permit requirements (see Resources for background).
