Drainage Master Plans for Alameda County Flood Control Zones

Presentation
The Alameda County Flood Control and Water Conservation District began a program in 2008 to implement the Watershed Studies Program. The Program examines Alameda County watersheds rainfall-runoff characteristics on a holistic scale.  It does so to determine how the District can best allocate its limited resources.  The studies undertaken by the Program are used to establish the basis for the District's Capital Improvement Program (CIP) and also refine District policy and design criteria for maintenance and land development projects. The Program's studies replicate the hydrological conditions and flood system performance throughout an entire watershed by employing sophisticated computer models. These comprehensive models realistically account for all critical elements in a drainage network and produce reliable assessments of the systems under stress including floodplains and severity of impacts.

The technology utilized by the Program includes a comprehensive GIS database, one- and two-dimensional hydrologic and hydraulic models that are calibrated using Doppler radar rainfall data and the Districts precipitation and stream gage data.  Wood Rodgers was contracted by the District to conduct the studies, and helped the District develop and refine the techniques used.

The presentation will provide a summary of the overall concept, the approach and tools used to develop these studies in Zones 3A and in Zone 6.
