Multech conducted a South San Francisco Bay fluvial sediment transport study for the U.S. Army Corps of Engineers, San Francisco District. The objective of the study was to estimate sediment supplies from the Guadalupe River, Coyote Creek, and other South Bay streams to facilitate planning of the South Bay salt ponds restoration project, which requires sediment to raise the beds of the salt ponds to create suitable wetlands to function as estuarine habitats. As the sediment supply to the San Francisco Bay from the Sacramento and San Joaquin Rivers has shown a decreasing trend, sediment supply from local tributaries has become an important part of the sediment budget of the Bay and accurate assessment of fluvial sediment supply from the South Bay streams is critical for proper planning of the restoration project. In this study, sediment transport of the Guadalupe River and Coyote Creek were investigated using the HEC-RAS models, while those from Calabazas, Stevens, and Permanente, and San Tomas Aquino Creeks were investigated based on available regional relationships between the watershed sediment yield and the drainage area.
