Summary

The U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center collected hydrodynamic and suspended sediment flocculation data at channel and shallow water sites in south San Francisco Bay in July 2020. The data were used to determine water column stratification, turbulence profiles, and floc size evolution. The goal of this project was to bound the controls on floc size and floc settling velocity to improve estimates of sediment fluxes and consider error in numerical models of sediment transport in San Francisco Bay. This data release includes hydrodynamic, sediment concentration, and particle size timeseries during July 2020, as well as sediment bed properties, water column particle size distributions, and CTD profiles [...]

Purpose

The purpose of this project is to investigate the variation in physical controls on floc size through the tidal cycle between the shallows and channel. Results will be used to advance understanding of suspended sediment dynamics for cohesive sediments, and to improve particle size approximations used in numerical sediment transport models. In San Francisco Bay, sediment transport plays a critical role in marsh restoration, the fate of disposed dredge material, contaminant transport, and geomorphic response to sea-level rise. Suspended material is important for limiting light penetration in the water column, protecting the system from harmful algal blooms. These data are intended for researchers, students, policy makers, and the general public.
