Shenandoah River Instream Flow Studies

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...

Low-Flow Characteristics of Virginia Streams

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...

Virginia Flood Investigations

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.

Peak-Flow Characteristics of Virginia Streams

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...

LSC Living Stream Laboratory (video)

Welcome to the Experimental Stream Lab at the US Geological Survey's Leetown Science Center in Kearneysville West Virginia. At this lab we're interested in stream ecology and how fish respond to land use and climate change. This experimental stream lets us test these questions in new ways. We have four stream channels comprising a series of pool and riffle chambers. We're learning how brook...
