Sediment transport, storage, and lag times in Chesapeake Bay watersheds- Katherine Skalak

Transport of sediment and particle-associated nutrients from upland watersheds into the Chesapeake Bay is an ongoing geomorphic and ecological concern for the region. Every year millions of dollars are spent on managing this flux. A “lag time” occurs between initiating a best management practice in a watershed and achieving the intended benefit in the estuarine receiving waters.

Physical, Chemical, and Biological Processes Affecting the Retention and Release of Organic Contaminants in Fractured Rock Aquifers- Allen Shapiro

Physical, chemical, and biological processes control the retention and release of organic contaminants in the matrix of fractured sedimentary rocks and affect the longevity of groundwater contamination and the design of groundwater remediation strategies.

Geomorphic influence on resilience of tidal freshwater wetlands to sea level rise- Greg Noe

Want to conduct collaborative eco-geomorphic research at the forefront of climate change impacts? We have a novel landscape-scale ecosystem experiment, using two adjacent tidal rivers with a 9x difference in watershed sediment loads, to determine how sediment availability regulates the resilience or loss of tidal freshwater wetlands as the result of sea level rise and salinization.

Piedmont and Blue Ridge Project

The Piedmont and Blue Ridge Project is a geologic mapping project supported by the USGS National Cooperative Geologic Mapping Program. The Piedmont Blue Ridge Project aims to understand the geologic framework and tectonic evolution of terranes and basins in the Appalachian Piedmont and Blue Ridge, and their significance for water, mineral and energy resources, natural hazards, and engineering/...

Coastal Basement Geology of the Southeastern U.S. Project

Starting October 2018, this pilot project initiated the first year of geologic mapping of coastal-plain basement rocks in South Carolina and Georgia to be completed in a second year, providing a prototype for cooperative basement geologic mapping throughout the Atlantic and Gulf Coastal Plains. Basement terranes and rift basins concealed beneath sediments of the southeastern U.S. coastal plain...

Piedmont Geology along the southeastern Fall Zone, Virginia and North Carolina – A Cooperative FEDMAP-STATEMAP-EDMAP Project

This task within the USGS NCGMP Piedmont-Blue Ridge Project aims to fill the void in geologic map coverage along the Fall Zone in southeastern Virginia and northeastern North Carolina, and forge strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting DMME and NCGS STATEMAP and UNC–W EDMAP components with targeted geologic mapping and...

Geologic Framework for Seismic Hazards in Central Virginia

The Central Virginia seismic zone (CVSZ) comprises an area of about 13,000 km2 in the Piedmont of central Virginia; seismicity in this zone is relatively frequent, but generally mild in magnitude. The August 2011 event was the largest earthquake recorded in the CVSZ since the development of modern seismic monitoring, and highlighted how little we actually know about this seismic...

A National-scale River Corridor Model- Jud Harvey

The need for better models and more effective use of data to characterize river corridor transport processes is keenly felt, from evaluating the effectiveness of river and watershed management practices all the way to clarifying regulatory authority under the Clean Water Act.

Collecting Ecological Data and Models of Living Shoreline Restoration Projects

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...
