Virginia CZM Program 2010 Coastal Grant Project Description and Final Summary

Project Task:

94.02

Grantee:

Virginia Institute of Marine Science

Project Title:

Shore Evolution in Several Virginia Localities 2010

Project Description as Proposed:

As part of a continuing, multi-year project, shore evolution has been documented in many localities in the Virginia portion of Chesapeake Bay. These data sets have been useful in a variety of ways. They have shown the rates and patterns of shore change through time at Virginia’s estuarine dunes. They have also been useful to many other research projects and advisory service activities at VIMS and other agencies. Orthorectification of historic and recent aerial photography and digitization of the shoreline show the geomorphic evolution of the coastal zone in terms of shoreline change and landuse as well as nearshore variations in sandbars and shoal where present.  We propose continuing this process for the Counties of Surry, King George, Prince William, and Richmond. The more rural localities are more challenging to the orthorectification process than developed localities, requiring more time. In addition, the farther from the main stem of the Chesapeake Bay the localities are, the less complete our photo archives are. This means that more photos will have to be purchased in order to complete sets for a locality. In addition to completing those listed above, three localities, Hampton, Middlesex, and Lancaster, will be updated and made more complete. When these localities were first analyzed for shoreline evolution several years ago, the focus was on the main shorelines. We will update these three localities to 2009 as well as include the historical photos in the smaller creeks and rivers.

Project Summary Provided by Grantee:

As part of a continuing, multi-year project, shore evolution has been documented in many localities in the Virginia portion of Chesapeake Bay.  These data sets have been useful in a variety of ways.  They have shown the rates and patterns of shore change through time at Virginia’s estuarine dunes.  They have also been useful to many other research projects and advisory service activities at VIMS and other agencies.  Orthorectification of historic aerial photography and digitization of the shoreline show the geomorphic evolution of the coastal zone in terms of shoreline change and land use as well as nearshore variations in sandbars and shoals where present. 

For this project, the photos were rectified and shorelines were digitized for these localities.

Surry - 1937, 1954, 1963, 1978, 1994, 2002, 2007, and 2009

Richmond – 1937, 1953, 1969, 1994, 2002, 2007, and 2009

King George – 1937, 1953, 1967,1981, 1994, 2002, 2006, and 2009

Prince William – 1937, 1953, 1962, 1985, 1994, 2002, 2007, and 2009

In addition to completing those listed above, three localities, Hampton, Middlesex, and Lancaster, were updated and made more complete.  When these localities were first analyzed for shoreline evolution several years ago, the focus was on the main shorelines.  These three localities were updated to include more recent dates as well as include the historical photos in the smaller creeks and rivers.

Lancaster:  Additional shoreline will be added to dates 1937, 1959, 1969, 1994, and 2002.  New dates added to database, 2009.

Middlesex:  Additional shoreline will be added to dates 1937, 1994, and 2002.  New dates added to database, 1959, 1968, and 2009.

Hampton:  Additional shoreline will be added to dates 1937, 1953, 1963, 1980, 1994, and 2002.  New dates added to database, 2006 and 2009.

Long-term, end point rate of shoreline change was determined between 1937 and 2009 for each locality.  The data were summarized in a locality report available on the VIMS, Shoreline Studies Program website.  http://web.vims.edu/physical/research/shoreline/Publications-Evolution.htm.  In addition, a copy of each report was sent to the locality administrator and director of planning for their use.
