Multibeam Delta Bathymetry Surveys
Description / purpose
The California Department of Water Resources (CA-DWR), North Central Region Office (NCRO), Bathymetry and Technical Support Section has conducted bathymetry surveys in the Delta since 2011 (according to the Bathymetry Catalog). Data have been used to support planning for the installation of behavioural fish barriers, to assess the river’s channel capacity and ability to convey flows, to assess water quality dynamics, to better understand the area’s risk of flooding and to improve the quality of flood hazard data and maps available to local communities (under the DWR’s FloodSAFE California Initiative), to improve knowledge of sediment presence and movement, to provide high-resolution bathymetry data for hydraulic models, to assess the placement of a drought barrier, to determine how the channel bottom is evolving due to the installation of an emergency drought barrier, and to determine the effects of fish passage projects.
