Surface Water

This successful partnership brings together Randolph-Macon College (RMC), Washington and Lee University (W&L), and Virginia Commonwealth University (VCU), in partnership with the US Geological Survey (USGS) to foster growth in Science, Technology, Engineering, and Math (STEM) through summer student internship experience, awareness of USGS science in the classroom, and increased understanding of...

Models are presented that describe Virginia urban area annual peak streamflow per square mile based on basin percent urban area and basin drainage area.

As urban and rural growth continues, competition for clean water expands into stream areas previously capable of meeting local water-use demands. Conflicts among instream and offstream users of streamflow increase as flows decrease. This research enhances understanding of summer low-flow conditions in the North Fork, South Fork, and Shenandoah Rivers, relating water availability to physical...

Understanding low flows in Virginia streams is essential to sound management of our water resources and associated riparian and watershed ecosystems. Meaningful characterizations of the magnitude, frequency, and duration of low flows provide valuable insights into the dynamics, variability, and flux associated with water movement through these unique stream systems. Improved estimates of low flows...

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 objective of the South River Mercury Total Maximum Daily Load (TMDL) study is to develop a better understanding of methyl mercury cycling in the South River and calculate mercury loading reductions that would protect fish from high mercury concentrations.

This project: (1) initiates a continuous water-quality monitoring study for the Roanoke River in the area upstream and downstream of the RRFRP project area; (2) provides a mechanism for detecting short- and long-term changes in Roanoke River suspended sediment water quality during and after the RRFRP implementation; and (3) assesses trends in suspended sediment water quality in this section of the...

The primary objective of the USGS monitoring effort will be to identify whether the construction of the Indian Creek pipeline crossings will adversely impact the sediment water quality in Indian Creek. To accomplish this goal, continuous real-time water-quality monitoring will be the primary focus of the effort.

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 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)...
