All Data

The data set contains information on potential population, economic, land cover, and infrastructure exposure to coastal hazards for coastal communities of the state of Virginia, USA. The type of information includes U.S. Census data on the number and types of residents, InfoGroup data on numbers and types of employees, county parcel values, NLCD land cover estimates, and infrastructure data on ro

Socioeconomic impact estimates of community exposure to future coastal hazards are presented for communities along the coast of U.S. Florida. The provided data were generated using the Hazard Exposure Reporting and Analytics (HERA) web application (www.usgs.gov/apps/hera/). HERA uses geospatial analysis of socioeconomic indicators (population, economic, land cover, and infrastructure) in combinat

Canadian discrete water quality data and daily streamflow records were evaluated using the Weighted Regression on Time, Discharge, and Seasons (WRTDS) model implemented with the EGRET R package (Hirsch et al. 2010, Hirsch and De Cicco 2015). Models were used to estimate loads of solutes and evaluate trends for three constituents of interest (selenium, nitrogen, and sulfate). Six models were genera

The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. During 2022, U.S. Army Corps of Engineers contracted the acquisitions of airborne lidar surveys of Mount St. Helens crater and two primary drainage

This metadata record describes model outputs and supporting model code for the Data-Driven Drought Prediction project of the Water Resources Mission Area Drought Program. The data listed here include outputs of multiple machine learning model types for predicting hydrological drought at select locations within the conterminous United States. The child items referenced below correspond to different

Brook Stickleback Culaea inconstans is an aquatic invasive species in Wyoming that may pose a risk to native biodiversity. Our aim was to evaluate the current risk Brook Stickleback poses to native fish species in the North Platte River drainage. We updated the current distribution of Brook Stickleback, evaluated for possible range expansion, and determined landscape-level habitat drivers and occu

This data is comprised of representative chloride values Seneca and Cayuga Lakes and their tributaries from many sources.

This dataset includes raw hydrologic data (streamflow data, groundwater level data, precipitation data) and geochemical data (geochemical results, fluorometric monitoring results) collected from January 1st, 2000 to December 31st, 2020 This dataset also includes interpreted results described in a U.S. Geological Survey Scientific Investigation Report (Goodling and others, 2023). This report descri

This data release contains the output of the National Hydrologic Hydrologic Model (NHM) version 1.0 aggregated to twelve-digit and ten-digit Hydrologic Unit Code (HUC) boundaries contained in the NHDPlus v2.1 dataset. The data are intended to provide "local" water budgets for each HUC boundary as total aggregated streamflow across HUC boundaries is not included. The HUC boundaries are periodically

A 3-dimensional (3D) synthetic model, using MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations were used to explore various parameter sensitivities and unsaturated zone thicknesses and their impact on heat transport as water enters the subsurface as infiltration, flows through the unsaturated zone to the water table, and eventua

A 3-dimensional (3D) synthetic model, built for running with MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations explore potential responses to within a watershed to climate warming along system pathways. The response analysis uses output from a 30-year warming period on a synthetic watershed patterned after a humid temperate cli

Six hypothetical 1-dimensional models are used to verify and demonstrate new unsaturated-zone heat transport functionality added to MT3D-USGS (version 1.1.0). Because the governing equations describing groundwater solute transport and heat transport have a similar form, MT3D-USGS may be applied to heat transport problems. Published examples of MT3DMS, from which MT3D-USGS is derived, as a heat tra
