Drag and sediment transport: conditions at the bottom boundary
Active
By Pacific Coastal and Marine Science Center
October 14, 2021
Research on bed sediment grain size, bedform morphology, vegetation characteristics, and sediment resuspension and transport.
This research is part of the project, “Sediment Transport in Coastal Environments.”
Objectives
Investigate the influence of seafloor properties, including bed sediment grain size, bedform morphology, and vegetation characteristics, on sediment resuspension and transport.
Develop parameterizations of the influence of seafloor properties on sediment transport for inclusion in numerical models.
Investigate the temporal variability of bed sediment grain size on event and seasonal time scales, and investigate the response of bedform morphology to changes in bed sediment grain size.
Collaborate with Team members in collecting oceanographic and sediment transport data to advance understanding of coastal ecosystems and coastal hazards.

Sediment Transport in Coastal Environments
Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to natural...
Coastal watershed and estuary restoration in the Monterey Bay area
Objectives: Support further work by the USGS and collaborating federal, state, and local agencies and academic partners in analyzing the effectiveness of restoration work in coastal watersheds and estuaries in the Monterey Bay area. The USGS will play a supporting role in field efforts led by NOAA and California State University - Monterey Bay to measure physical and ecological changes in the...
Transport of invasive microorganisms
The objectives of his project are to investigate the vectors and timing of microbiological invasions and the subsequent dispersal of these non-native organisms due to sediment transport. We will attempt to confirm the identification of specific invasives encountered with molecular sequencing, monitor the spread of the invading populations through their recent distribution and the historic...
Sediment transport in submarine canyons
Objectives: Produce a step-change in understanding of submarine turbidity currents by measuring their two key features (synchronous velocity and concentration profiles) in detail (every 2-to-30 seconds) for the first time, and documenting spatial changes in their flow velocity from source-to-sink for the first time.
Columbia River estuary
This research is part of the project “Sediment Transport in Coastal Environments.” We aim to support regional sediment management in the Columbia River littoral cell by monitoring and modeling shoreline change, modeling fate of disposed dredged material, and studying bedform morphology.
Sediment transport between estuarine habitats in San Francisco Bay
We investigate mechanisms of sediment transport, resuspension dynamics in shoals, wave evolution in the shallows, wave attenuation in marshes, and transport of sediment between mudflats and marshes. We produce data sets for calibration of and comparison with sediment transport models, including wave parameters, suspended sediment concentration, and sediment flux.

San Francisco Bay geomorphology
The primary objective of this task is to develop tools for predicting the long-term geomorphic evolution of estuaries. Sediment core and historical change analysis will be used in combination with interpretation of high-resolution seismic profiles to develop tools for predicting geomorphic evolution of estuaries. Historical change analysis will use hydrographic and lidar data. Longer-term data...
Ecosystem Engineers: Impacts of Invasive Aquatic Vegetation on the Delta’s Critical Ecosystems
The Sacramento-San Joaquin Delta (Delta) is home to a diverse community of plants and animals and is the hub of California’s freshwater delivery system. The Delta supplies water for over 25 million Californians and supports millions of acres of farming, commercial and sport fishing, shipping and ports, and recreational boating.

Installing weather station in Grizzly Bay
Pete Dal Ferro and Andrew Stevens, both from the USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, install a Vaisala WXT weather station in Grizzly Bay, east of San Pablo Bay and northeast of San Francisco.
Grizzly Bay dolphin with weather station installed on top
A structure called a dolphin, permanently affixed in the sediment, stands in Grizzly Bay near San Francisco, CA, with a weather station installed on top. The USGS will use the data from the weather station in conjunction with other oceanographic data, in their studies of sediment movement in the bay.

Weather station power supply and modem
A weather station, installed in the middle of Grizzly Bay east of San Pablo Bay (near San Francisco), gets its power from a small solar panel. Data collected from the station is transmitted via a wireless modem. Far in the background is the city of Benicia, and the plume rising into the sky is water vapor emitted from the Benicia oil refinery.
