Sedimentation and bathymetric change in San Pablo Bay: 1856-1983 Sedimentation and bathymetric change in San Pablo Bay: 1856-1983

A long-term perspective of erosion and deposition in San Francisco Bay is vital to understanding and managing wetland change, harbor and channel siltation, and other sediment-related phenomena such as particle and particle-associated substance (pollutants, trace metals, etc.) transport and deposition. A quantitative comparison of historical hydrographic surveys provides this perspective...
