Acoustic doppler current profiler (ADCP) transect data at Benicia Bridge and Mallard Island, 2019 Acoustic doppler current profiler (ADCP) transect data at Benicia Bridge and Mallard Island, 2019
Field observations of water and suspended-sediment fluxes were conducted at Benicia Bridge and Mallard Island during the 2019 water year wet season to capture suspended-sediment flux during elevated Sacramento-San Joaquin Delta discharge. Measurements occurred on two occasions: 1) 26th of February 2019 at Benicia Bridge and Mallard Island, following a storm event that increased delta...
Erodibility Data from Gust Erosion Chamber Experiments in Grizzly Bay and San Pablo Bay, California, Winter 2020 Erodibility Data from Gust Erosion Chamber Experiments in Grizzly Bay and San Pablo Bay, California, Winter 2020
A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained from San Pablo and Grizzly (within Suisun) Bays in California. A pair of sediment cores were collected from the same approximate locations in each bay five times between January 22nd, 2020 and March 11th, 2020 for a total of 10 experiments and 20 sediment core results. Locations were chosen to...
Hydraulic modeling and flood-frequency analyses using paleoflood hydrology for the Tennessee River near Chattanooga, Tennessee Hydraulic modeling and flood-frequency analyses using paleoflood hydrology for the Tennessee River near Chattanooga, Tennessee
This data release contains the results from a comprehensive field study that applied paleoflood hydrology methods to estimate the frequency of low-probability floods for the Tennessee River near Chattanooga, Tennessee. The study combined stratigraphic records of large, previously unrecorded floods with modern systematic flood records and historical flood accounts.
Pacific common eider (Somateria mollissima v-nigrum) nest records, Yukon-Kuskokwim Delta, Alaska, 1991-2004 Pacific common eider (Somateria mollissima v-nigrum) nest records, Yukon-Kuskokwim Delta, Alaska, 1991-2004
This data are a single table of nest records from a multi-year study of Pacific Common Eider (Somateria mollissima v-nigrum) biology that was conducted along the lower Kashunuk River, Kigigak Island, and the mouth of the Tutakoke River on the Yukon-Kuskokwim Delta from 1991-2004.
Colorado River at Salt Wash near Moab, UT - 2020/10/07 Particle Image Velocimetry Colorado River at Salt Wash near Moab, UT - 2020/10/07 Particle Image Velocimetry
The dataset consists of a shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Salt Wash near Moab, UT, on October 7, 2020. The dataset contains approximately 3 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned...
Multi-grid Analysis of Point Stability Tool Multi-grid Analysis of Point Stability Tool
Elevation-change datasets can also be used to identify stable and unstable areas of the seafloor. The Multi-grid Analysis of Point Stability (MAPS) program was created to automate this process. This program is used to locate persistent areas of user-defined seafloor stability and/or instability at common geographic locations from multiple elevation-change datasets (grids) representing...
