Northern Virginia Stream Restoration Bank
Wetland Studies and Solutions, Inc. restored 11 miles of streambank using natural channel design techniques, resulting in the first dedicated stream bank in Virginia.
Northern Virginia Stream Restoration Bank (NVSRB) was the first dedicated stream bank in Virginia and is comprised of approximately 11 miles of restored streams, that were restored using a phased construction approach that began in February 2008.
The streams have been restored through the use of natural channel design (NCD) techniques that include raising the bed to reconnect higher storm flows with the floodplain. Design flow rates were developed through assessment of various design protocols, including hydrologic modeling using HEC-HMS. Hydraulic performance of the restoration designs were confirmed using HEC-RAS.
Some reaches have completed their 10th growing season – and all reaches have met (and exceeded) monitoring requirements.
