Virginia CZM Program: 2006 Coastal Grant Project Description and Final Summary

Project Task:

94.05

Grantee:

Virginia Institute of Marine Science

Project Title:

'Sands of the Chesapeake' Update and Dune Monitoring

Project Description as Proposed:

In 2007, the Shoreline Studies Program at VIMS contracted with DEQ and NOAA to create an educational brochure entitled “Sands of the Chesapeake” describing the 10 years of scientific analysis of dunes and beaches in Chesapeake Bay.  The culmination of this research was a change to the Code of Virginia made by the General Assembly in 2008 that extended protection for dunes to all Virginia Tidewater localities.  The brochure was well received, and the initial printing of 300 copies has been distributed.  In order to have the most up-to-date brochure, we propose reworking the existing document to reflect these changes and reprinting.

The Shoreline Studies Program at VIMS established a beach and dune monitoring program for nine sites around the Virginia portion of Chesapeake Bay.  These sites were monitored twice yearly for four years (2001-2004).  In addition to three years of relatively calm conditions, these data included the impact of Hurricane Isabel, a nearly 100-yr event, on the Bay’s shorelines.  The shoreline’s change due to the storm and their subsequent short-term recovery was documented by this data.  However, since the end of the monitoring program other events have impacted Chesapeake Bay shorelines.  In order to document the longer-term recovery of these systems, additional monitoring is necessary.  Several of these sites are man-influenced and have upland development behind the dune.  Understanding storm impacts and shoreline recovery is critical knowledge when determining the suitability of living shoreline options (i.e. beach/dune) in higher energy environments.  In addition, the overall stability of these sites and their response to physical forcing can provide important information when developing guidelines for beach and dune encroachment.  We propose to perform cross-shore surveys at least five of the nine monitoring sites.

Project Summary Provided by Grantee:

In 2007, the Shoreline Studies Program at VIMS contracted with DEQ and NOAA to create an educational brochure describing the 10 years of scientific analysis of dunes and beaches in Chesapeake Bay.  The brochure was well received and the initial printing of 300 copies has been distributed.  Because this research resulted in a change to the Code of Virginia in 2008 in which protection was extended to all dunes in Virginia Tidewater localities, the brochure became out of date.  In order to have the most up-to-date brochure, the existing document was reworked to reflect these changes and reprinted.

The Shoreline Studies Program at VIMS established a beach and dune monitoring program for nine sites around the Virginia portion of Chesapeake Bay that were profiled semi-annually between 2001 and 2004.  Cross-shore surveys were performed at 6 sites, the data analyzed and a report written.  Each site varied in its performance since the last survey.  At MA3, the dune is accreting on the northernmost section and the beach stable.  However, at the southern end, the results were mixed with some beach and/or dune erosion although MA3-7 is stable to accretionary.  At NH10, the beach is erosional beach, but not much change has yet occurred in the dune area.  NH17 is accreting on its southern end, but the northern section is erosional. The southern section at NH51 is erosional while the northern section accretionary.  NL58 slightly erosional with a couple areas of accretion, but NL59 is erosional, and the western end of the site is no longer a dune and at the eastern end, the secondary dune has become the primary dune.
