Model parameter input files to compare the influence of channels in fringing coral reefs on alongshore variations in wave-driven runup along the shoreline Model parameter input files to compare the influence of channels in fringing coral reefs on alongshore variations in wave-driven runup along the shoreline
An extensive set of physics-based XBeach Non-hydrostatic hydrodynamic model simulations (with input files here included) were used to evaluate the influence of shore-normal reef channels on flooding along fringing reef-lined coasts, specifically during extreme wave conditions when the risk for coastal flooding and the resulting impact to coastal communities is greatest. These input files...
Interpolated hydrogeologic framework and digitized datasets for upstate New York study areas Interpolated hydrogeologic framework and digitized datasets for upstate New York study areas
This data release contains digital hydrogeologic datasets compiled for eight valley-fill aquifer systems in upstate New York. The data sets include input data necessary to create and interpolate the hydrogeologic framework of the aquifers and surrounding till-covered uplands. Input data is provided as point feature classes and georeferenced files of previously published reports along...
Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020 Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina, and the surrounding region. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding placer deposits containing critical mineral resources...
Data for leaf photosynthesis and net ecosystem exchange of CO2 and CH4 from wetland forest, marsh, and mudflats under simulated ambient and elevated atmospheric carbon dioxide (2013-2014) Data for leaf photosynthesis and net ecosystem exchange of CO2 and CH4 from wetland forest, marsh, and mudflats under simulated ambient and elevated atmospheric carbon dioxide (2013-2014)
This study evaluated the net ecosystem exchange of CO2 and CH4 from experimental wetland mesocosms established in elevated CO2 and ambient CO2 glasshouses at the U.S. Geological Survey’s Wetland and Aquatic Research Center (Lafayette, Louisiana). The study duration was approximately two years, and these data represent measured and calculated data from four time points, which the...
Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2019 Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2019
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is a natural laboratory for research on runoff-initiated debris flows (Coe et al., 2010). In 2019, there were two monitoring stations operating at Chalk Cliffs. The Upper Station drains an area of 0.06 km2 and was used to monitor flow properties and triggering conditions in the headwaters of the study area. It was equipped...
Geomorphic Monitoring Associated with the 2020 Pilchuck Dam Removal Geomorphic Monitoring Associated with the 2020 Pilchuck Dam Removal
The Pilchuck Dam, a low-head dam previously used for water-supply diversion in Snohomish County, Washington was removed from the Pilchuck River in the summer of 2020 after having blocked upstream fish migration for over a century. That removal effort was led by the Tulalip Indian Tribe; the USGS, in collaboration with the tribe, monitored sediment evacuation from the impoundment and...
