Point cloud, raster, and GNSS survey data from laser scanning of a debris flow basin near El Portal, California, USA Point cloud, raster, and GNSS survey data from laser scanning of a debris flow basin near El Portal, California, USA
This data release is composed of point cloud data from a terrestrial lidar survey, GNSS survey data, and derivative raster data. The data were collected on November 09, 2023. This survey was used to characterize a debris flow basin near El Portal, California for the National Park Service.
Phosphorus and nitrogen cycling in streambed and suspended sediment in Bois Brule and Siskiwit Rivers WI, 2021-2023 Data Phosphorus and nitrogen cycling in streambed and suspended sediment in Bois Brule and Siskiwit Rivers WI, 2021-2023 Data
Lake Superior is historically a nutrient poor lake that does not typically support significant cyanobacterial blooms. However, the lake has been experiencing an increase in blooms in the western portion of the basin recently. The largest blooms documented have occurred after recent major flooding events, indicating that nutrients transported to the lake during these events may be a...
Simulated coastal fine-grained sediment plumes from beach nourishment near Santa Barbara, California Simulated coastal fine-grained sediment plumes from beach nourishment near Santa Barbara, California
A coupled hydrodynamic and sediment transport model was developed to simulate the dispersal of fine-grained sediment from beach nourishment projects near Santa Barbara, California. The model simulations were used to quantify the size and extent of sediment plumes resulting from nourishment projects and evaluate the potential impacts of beneficial use of fluvial sediment captured in...
Bathymetric Survey of Upper Lake Mary near Flagstaff, Arizona in 2024 - Digital Elevation Model Bathymetric Survey of Upper Lake Mary near Flagstaff, Arizona in 2024 - Digital Elevation Model
The City of Flagstaff in northern Arizona utilizes Upper Lake Mary reservoir for approximately 25 to 30 percent of its water supply and understanding the detailed topography of the storage basin is essential for effective water management. The U.S. Geological Survey incorporated modern bathymetric and ground survey techniques to construct a 1-meter (1m) resolution digital elevation model...
GSFLOW model to extend the San Antonio Creek Integrated Model and simulate future water availability scenarios, San Antonio Creek Valley watershed, Santa Barbara County, California GSFLOW model to extend the San Antonio Creek Integrated Model and simulate future water availability scenarios, San Antonio Creek Valley watershed, Santa Barbara County, California
In the San Antonio Creek Valley Watershed (SACVW) of Santa Barbara County, California, climatic conditions, surface-water diversions, and groundwater withdrawals potentially affect water availability, magnitude of streamflow in San Antonio Creek, and the extent and quality of protected species habitat in the Barka Slough wetland. Future climate in central California may have warmer and...
