An important part of the Virginia Department of Transportation's missions is the safe maintenance, design, and constructions of bridges that cross-waterways and wetlands in the State. The data collected by USGS in conjunction with this project is a vital element of the overall task and mission of the Virginia Department of Transportation.

Economic growth and the development, management, and protection of Virginia’s natural resources require anticipating peak stream flows and changes in peak stream flows over time. Extensive hydraulic analysis and smart design are needed to limit the environmental impacts of buildings, pavements, highways, and bridges. Effective design and placement of structures built near streams and on flood...

The USGS Virginia Water Science Center has characterized both streamflow statistics and the fractured-rock aquifer systems in the region of Bedford County by maintaining relevant, long-term, hydrogeologic data collection as well as developing numerical modeling tools, which provides information that can be used to guide the development and management of the water resources within the County. The...

Objectives of the program are to (1) evaluate the spatial and temporal distribution of chloride concentrations in the aquifers, (2) evaluate the factors that affect the spatial and temporal distributions of chloride, and (3) assess the potential for upcoming or lateral intrusion of saline water in the aquifers.

Groundwater is a heavily used source of water in the Virginia Coastal Plain. Long term and widespread groundwater withdrawals have resulted in regional water-level declines, and created the potential for saltwater intrusion. Sound management of this vital resource relies on continual improvement of the scientific understanding of the aquifer system.

The U.S. Army Corps of Engineers (USACE), Wilmington District and the City of Roanoke, Virginia began construction of a congressionally authorized Roanoke River Flood Reduction Project (RRFRP) in 2005. RRFRP implementation activities include: construction activities, stream bank vegetation changes, and floodplain geometry changes which are occurring in a complicated urban river system. These...

Properly developed regional curves for a specific hydro-physiographic province are an invaluable tool for stream restoration design. Development of regional curves specifically for physiographic provinces of Virginia will enhance the ability to develop successful natural channel designs based on climatic, geologic, and hydrologic characteristics of specific regions of the state.

The purpose of the Virginia Beach shallow aquifer study is to better understand the distribution of fresh groundwater, its susceptibility to contamination, and its sustainability as a long-term water supply. Virginia Beach is a growing city in southeastern Virginia with a limited supply of fresh water. Most of the city’s drinking water, up to 45 million gallons per day, comes from Lake Gaston. The...

The objective of this study was to better characterize the aquifer systems in the Northern Shenandoah Valley and provide relevant hydrogeologic information that could be used to guide the ongoing development and management of these water resources in Clarke County.

The USGS, with cooperation from the Virginia Department of Environmental Quality and the Hampton Roads Planning District Commission, is involved in several related and on-going regional projects directed at better characterization of this important resource. The large amount of information needed for these projects requires the development and integration of a Geographic Information System (GIS)...

The objective of this study is to better characterize the carbonate aquifer system in the Northern Shenandoah Valley and provide relevant hydrogeologic information that can be used to guide the development and management of this important water resource.
