Virginia has a total area of 42,774.2 square miles, including 3,180.13 square miles of water, making it the 35th-largest state by area. The Chesapeake Bay separates the contiguous portion of the Commonwealth from the two-county peninsula of its Eastern Shore. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay.

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...
