Hydrologic and Erosion Responses of Burned Watersheds

The enhanced probability of catastrophic wildfires has increased our need to understand the risk of floods, erosion, and debris and contaminant transport in burned watersheds. This project investigates the relation between rainfall intensity and peak discharge; erosion and deposition processes; and water-quality impacts to minimize the loss of life and property resulting from post-wildfire...

Office of the Delaware River Master

In 1954, the U.S. Supreme Court issued a Decree in State of New Jersey v. State of New York and City of New York in which the Court established the position of the Delaware River Master.  The Court directed that the River Master perform multiple duties and functions including administering the provisions of the Decree relating to yields, diversions, and releases; conserving the waters of the...

Total Water Use

The USGS has estimated water use for the United States every 5 years since 1950. Estimates are provided for groundwater and surface-water sources, for fresh and saline water quality, and by sector or category of use. Estimates have been made at the State level since 1950, and at the county level since 1985. Water-use estimates by watershed were made from 1950 through 1995, first at the water-...

Surface-Water Use

Surface-water sources include streams and rivers, lakes and reservoirs, and oceans. For the purposes of the USGS water-use reports, surface water with less than 1,000 milligrams per liter (mg/L) of dissolved solids is considered freshwater, and the remainder is considered saline.

Surface-water resources are often evaluated by watershed. The most recent USGS water-use estimates by...

Groundwater Use

Groundwater refers to all subsurface water, specifically that part of groundwater which is in the saturated zone. Groundwater sources are called aquifers: geologic formations that contain sufficient saturated permeable material to yield significant quantities of water to wells and springs. For the purposes of the USGS water-use reports, groundwater with less than 1,000 milligrams per liter (mg...

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 the Surge, Wave, and Tide Hydrodynamics (SWaTH) Network along the Northeastern Atlantic Coast. SWaTH monitors and documents the height, extent, and timing of storm...

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.

Transportation-Related Water Projects

The USGS has a long history of cooperative investigations with the Federal Highway Administration (FHWA) and state highway agencies to provide data and information to address various issues related to water resources and the Nation’s transportation infrastructure. These issues cover a wide spectrum and include items such as regional flow statistics, flood documentation, regional stream...

Fluvial Sediment and Geomorphology: Resources for Monitoring and Analysis

The USGS collects fluvial sediment and geomorphic data and conducts related research at numerous sites across the Nation. This information is essential to informed solutions to sediment-related and overall water resource management issues.

Emerging Contaminants

Emerging contaminants, or contaminants of emerging concern, can refer to many different kinds of chemicals, including medicines, personal care or household cleaning products, lawn care and agricultural products, among others. These chemicals make it into our Nation's lakes and rivers and have a detrimental affect on fish and other aquatic species. That have also been shown to...

Groundwater Quality Research

Every day, millions of gallons of groundwater are pumped to supply drinking water for about 140 million people, almost one-half of the Nation’s population. Learn about the quality and availability of groundwater for drinking, where and why groundwater quality is degraded, and where groundwater quality is changing.
