Shore Status, Evolution, And Storm Vulnerability Assessments For George Washington Birthplace National Monument, C. Scott Hardaway Jr., Donna A. Milligan, Kevin P. O'Brien, Christine A. Wilcox

Reports

The shoreline at the George Washington Birthplace National Monument (GEWA) is eroding and vulnerable to storms. Recent storms, such as Hurricane Isabel and Tropical Storm Ernesto impacted the region in 2003 and 2006, respectively. Large losses of the bank prompted the National Park Service to determine the vulnerability of the shore and its associated cultural, natural and archeological resources. This project maps the existing shoreline along the Potomac River and at the Memorial House on Popes Creek, provides an assessment of shore and bank dynamics, determines the rate of shoreline change between 1937 and 2007, and presents an analysis of …


Dune Monitoring Data Update Summary, Kevin P. O'Brien, Donna A. Milligan, George R. Thomas Mar 2009

Dune Monitoring Data Update Summary, Kevin P. O'Brien, Donna A. Milligan, George R. Thomas

Reports

The Shoreline Studies Program at VIMS established a beach and dune monitoring program for nine sites around the Virginia portion of Chesapeake Bay (Milligan et al., 2005). 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 …

Occohannock Creek Shoreline Erosion Assessment And Living Shoreline Options Report, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine Wilcox, Shoreline Studies Program, Marcia Berman, Sharon Killeen, Tami Rudnicky, Center For Coastal Resources Management

Reports

This study provides information to Occohannock Creek property owners to help them assess their shoreline stability and their options if erosion is a problem. In the past, shoreline erosion control options were typically limited to rip-rap, groins, or bulkheads. These hard structures often destroyed marsh and other habitat and may not have provided the protection desired. Other methods of erosion control now exist that have been used in a variety of conditions and evaluated for their durability and performance. The alternative techniques incorporate vegetation and are referred to as Living Shoreline designs. Conditions on Occohannock Creek make it a very …

Performance Of Sills: St. Mary’S City, St. Mary’S River, Maryland, C. Scott Hardaway Jr., W. G. Reay, Jian Shen, Scott Lerberg, Donna A. Milligan, Christine A. Wilcox, Kevin P. O'Brien

Reports

Living shorelines represent a shoreline management option that combines various erosion control methodologies and/or structures while at the same time restoring or preserving natural shoreline vegetation communities. A common living shoreline design in Chesapeake Bay includes a low offshore rock sill to absorb wave energy with an emergent wetland landward of the sill to enhance erosion control, provide critical habitat, and improve water quality condition. This study is part of a larger, ongoing project to (1) evaluate erosion control effectiveness and the sustainability of offshore sill and fringing marsh design and structure, (2) evaluate ecological services (e.g., habitat value, water …

Dune Evolution Middlesex County, Virginia Rappahannock River And Piankatank River Shorelines, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Christine A. Wilcox, George R. Thomas, Kevin P. O'Brien

Reports

Shoreline evolution is the change in shore position through time. In fact, it is the material resistance of the coastal geologic underpinnings against the impinging hydrodynamic (and aerodynamic) forces. Along the shores of Chesapeake Bay, it is a process-response system. The processes at work include winds, waves, tides and currents, which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change but it is as important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed …

Tangier Island, Virginia Shoreline Management Plan For The West Coast Of The Uppards, C. Scott Hardaway Jr. Apr 2004

Tangier Island, Virginia Shoreline Management Plan For The West Coast Of The Uppards, C. Scott Hardaway Jr.

Reports

Utilizing geo-rectified aerial photography from 1938, 1960, 1987, and 2001, shoreline change rates were determined along the Uppards. Shoreline change rates vary but are all erosional except for areas around the north end where sand bars come and go. In the area of concern between baseline stations 4000 and 4600, the rates of erosion have increased with time. Using the rate calculated from the 1938 to 2001 shorelines for station 4000, 16 ft/yr, the 400 ft marsh isthmus width between the shoreline and Toms Gut would breach in about 25 years. This would essentially break the Uppards in two and …

An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr. Nov 2002

An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr.

Reports

This project was done in response to concerns by environmental resource managers of historic and potential adverse impacts to Virginia’s secondary dune ecosystems. Virginia environmental regulatory programs have little decision-making authority over the use of secondary dunes as these areas are not included in the Coastal Primary Sand Dune Act (the Dunes Act). These areas function as estuarine edge habitat and provide natural upland erosion control, and are thus valuable to estuarine and coastal plain fauna and adjacent upland property owners.
