Surge, Wave, and Tide Hydrodynamics (SWaTH) Network
During large coastal storms, the storm surge and waves are the main cause of destruction and landscape change, transporting saline water, sediment, and debris inland. The USGS, in collaboration with stakeholders, has constructed a national Surge, Wave, and Tide Hydrodynamics (SWaTH) Network for the Atlantic, Eastern Pacific, and Central Pacific. SWaTH monitors and documents the height, extent, and...
USGS Flood Event Viewer: Providing Hurricane and Flood Response Data
During large, short-term floods, the USGS collects additional data to help document these high-water events. This data is uploaded to the USGS Short-Term Network (STN) for long-term archival, and served out to the public through the USGS Flood Event Viewer (FEV) which provides convenient, map-based access to storm-surge and other event-based data.
USGS Cooperative Matching Funds
USGS Cooperative Matching Funds (CMF) support joint projects with our state, regional, tribal, and local partners to provide reliable, impartial, and timely information needed to understand and manage the Nation's water resources.
Focus Area Studies
Focus Area Studies were stakeholder-driven assessments of water availability in river basins with known or potential conflict. They contributed toward ongoing assessments of water availability in large watersheds, provided opportunities to test and improve approaches to water availability assessment, and informed the National Water Census with local information. These studies focused on key water...
NASA-USGS National Blue Carbon Monitoring System
The NASA-USGS National Blue Carbon Monitoring System project will evaluate the relative uncertainty of iterative modeling approaches to estimate coastal wetland (marsh and mangrove) C stocks and fluxes based on changes in wetland distributions, using nationally available datasets (Landsat) and as well as finer scale satellite and field derived data in six sentinel sites.
Acid Rain
The USGS has been at the forefront of studying the impacts of acid rain for decades. How does acid rain form? What does it do to the landscape? Can it burn you like battery acid? Keep reading to find out more...
Large Oil Spills
Oil spills, such as the 2010 Deepwater Horizon Oil Spill, are impactful environmental disasters that have long lasting effects to the landscape, native species, and inhabitants who depend on the area. The USGS explores the adverse effect that large-scale oil spills have on the environment and helps responders prepare for environmental recovery and rehabilitation.
Linking Selenium Sources to Ecosystems: Local and Global Perspectives
The sources, biogeochemistry, and ecotoxicology of selenium (Se) combine to produce a widespread potential for ecological risk such as deformities in birds and fish. Linking the understanding of source characteristics to a mechanistic, biodynamic dietary model of Se exposure on an ecosystem-scale improves the prediction of Se effects and its potential remediation.
Regional Groundwater Availability Studies
Regional groundwater availability studies enable information about groundwater to be integrated and consistent, so that this resource can be analyzed and understood on an aquifer–wide scale. These studies provide decision–makers with a better understanding of the status and trends in the Nation's groundwater availability.
Historical Flooding
The USGS provides practical, unbiased information about the Nation's rivers and streams that is crucial in mitigating hazards associated with floods. This site provides information about the USGS activities, data, and services provided during regional high-flow events, such as hurricanes or multi-state flooding events. The USGS response to these events is typically managed by the National Flood...
Coastal Carolinas Focus Area Study
The USGS is undertaking a 3-year study of water availability and use to investigate competing societal and ecological needs in Southeastern Atlantic Coastal Basins of the Carolinas. This study will compile existing information, add new scientific data and interpretation, and develop tools to help resource managers and stakeholders address current and future water-use challenges.
Red River Focus Area Study
The USGS is undertaking a 3-year study of water use, availability, and change in the Red River basin, which covers more than 93,000 square miles in New Mexico, Texas, Oklahoma, Arkansas, and Louisiana. Water resources are being stressed by increasing water demands and increasingly severe droughts, and a comprehensive water-resource assessment of the basin is needed to enable sustainable water use.
