2024 Post-Wildfire Debris-Flow Hazard Assessments 2024 Post-Wildfire Debris-Flow Hazard Assessments
Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey (USGS) conducts debris-flow hazard assessments for recent wildfires. This collection holds all postfire debris-flow...
Grain-size analysis of sediment samples collected in the nearshore zone offshore of Marconi Beach, Wellfleet, MA, December 9, 2024 Grain-size analysis of sediment samples collected in the nearshore zone offshore of Marconi Beach, Wellfleet, MA, December 9, 2024
The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center deployed a nanopod to collect measurements of winter wave conditions directly offshore of Marconi Beach in Wellfleet, MA. Supplementary sediment samples were collected to characterize grain size. Marconi Beach is the site of ongoing measurements of wave runup, and this field work provides information on the...
U-Th-Pb Geochronology of the Mentor Anorthosite Intrusive Complex (MAIC) and Regional Plutonic Units U-Th-Pb Geochronology of the Mentor Anorthosite Intrusive Complex (MAIC) and Regional Plutonic Units
This U.S. Geological Survey (USGS) data release accompanies planned publication 'Geophysical architecture and geochronology of the Neoarchean Mentor anorthosite intrusive complex, northwestern Minnesota: largest anorthosite complex of the Superior Province?'. The data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb zircon geochronology data...
Stormwater treatment pond water-quality load and concentration data at Cherokee Park, Madison, Wisconsin, 2020–24 Stormwater treatment pond water-quality load and concentration data at Cherokee Park, Madison, Wisconsin, 2020–24
A stormwater pond in Cherokee Park, Madison, Wisconsin was monitored to determine if changes to street cleaning operations in the contributing drainage area would influence pollution reduction efficiency. Event-based water samples were collected from the ponds inlets and outlet from September 2020 through October 2024 and analyzed for nitrogen, phosphorus, sediment and chloride...
Integrated Hydrological Model for Simulating the Impacts of Spring Diversions on Streamflow in the Strawberry Creek Watershed, San Bernardino County, California Integrated Hydrological Model for Simulating the Impacts of Spring Diversions on Streamflow in the Strawberry Creek Watershed, San Bernardino County, California
The Strawberry Creek watershed, situated in the San Bernardino Mountains of southern California, features a group of natural springs known as Arrowhead Springs that have been augmented with diversions in the form of sub-horizontal borings and tunnels. Understanding the impact of these structures on streamflow through groundwater capture is crucial for understanding the impacts of spring...
