Roads and bridges are vulnerable to a range of stressors, such as flooding, heat waves, and other extreme events. The probability of these stressors impacting roads and bridges cannot be exactly calculated due to various uncertainties related to the scientific understanding of future environmental conditions. Resilient design methods find ways to account for the uncertainty in various...

Streamflow in a river can be used to calculate loads of constituents of concern in rivers but obtaining streamflow data using traditional streamgaging techniques in ephemeral channels can be cost prohibitive. Because of the remote location and infrequent flow occurrences, collecting paired stage-streamflow measurements for sufficient flow events during a 2-year study to develop a rating...

This data release presents data and calculations for morphometric parameters, median and maximum unfiltered concentrations used in statistical analyses, and stream lengths through geologic units that contain elevated concentrations of constituents of concern used for the publication, "Morphometric and geologic characterization with statistical correlations for 33 tributary drainage...

This data release contains nearshore bathymetry measurements collected at Point Barrow, Alaska in July 2022. These data were collected as part of an effort to monitor and forecast coastal flooding and erosion. They are also intended for reuse by scientists, managers, and the general public.

Bulk organic geochemical, major and trace element, and mineralogical data have been collected for core and cuttings samples of the Eocene Green River Formation from thirty-four wells in the Uinta Basin of Utah. The samples were collected from the U.S. Geological Survey Core Research Center in Denver, CO and the Utah Core Research Center in Salt Lake City, UT and represent multiple...

Variability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water...

Microcystin-LR (MC-LR), a cyanotoxin produced during some harmful algal blooms (HABs), can have negative impacts on water ecosystems. Current treatment methods have potential drawbacks: physical removal can cause cell lysis and toxin release, and chemical treatment can cause disinfection byproducts (DBPs). Ultraviolet C (UV-C) treatment can degrade cyanotoxins without producing...

This data release consists of a series of seamless topobathymetric digital elevation models (TBDEMs) for coastal Alaskan communities. Each TBDEM was assembled from best available, multi-source topographic and bathymetric elevation data collected at the time of processing. These products were created to support the development of dynamic flood models, but are also intended for reuse by...

Since 2005, the U.S. Geological Survey - Great Lakes Science Center's Lake Erie Biological Station (LEBS) has participated in a collaborative, multiagency effort to assess pelagic prey fish populations in the western (WB), central (CB), and eastern (EB) basins of Lake Erie through a combination of hydroacoustic and midwater trawl sampling. Assessing lake-wide distribution and abundance...

These field data such as first floor elevation and bathymetric surveys were collected to support development of coastal mapping products and advance storm response and recovery in Alaskan coastal communities. The data consists of essential community infrastructure elevation data to better understand flood exposure and support analysis of flood mitigation solutions, bathymetric surveys to...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

This data release contains three different estimates of road deicing salt applications, which utilize different sources of deicing salt data, and climate, land cover, and imperviousness data to provide spatially distributed estimates of deicing salt application for states covering the Delaware River Basin from water and calendar years 2001 through 2023 at a 30-meter spatial resolution...
