2009 York County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel E. Schatt, David Weiss

Reports

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

The 2009 Inventory for York County was updated using on-screen, digitizing techniques in ArcMap v10.0 while …

City Of Newport News, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Tamia Rudnicky, Daniel Schatt, Dave Weiss

Reports

This shoreline inventory is developed as a tool for assessing conditions along the tidal shoreline in the City of Newport News. Field data were collected during July and September 2002, and data were updated using VBMP 2006/2007 imagery. Conditions are reported for three zones within the immediate riparian river area: riparian land use, bank and buffers, and the shoreline. A series of maps and tabular data are published to illustrate and quantify results of an extensive shoreline survey. Shorelines of the James River, Skiffes Creek, Warwick River and Deep Creek, including small tributaries, were surveyed. Some sections were coded using …

Global Change And Eutrophication Of Coastal Waters, N. N. Rabalais, R.E. Turner, Robert J. Diaz, Dubravko Justic Aug 2009

Global Change And Eutrophication Of Coastal Waters, N. N. Rabalais, R.E. Turner, Robert J. Diaz, Dubravko Justic

VIMS Articles

The cumulative effects of global change, including climate change, increased population, and more intense industrialization and agribusiness, will likely continue and intensify the course of eutrophication in estuarine and coastal waters. As a result, the symptoms of eutrophication, such as noxious and harmful algal blooms, reduced water quality, loss of habitat and natural resources, and severity of hypoxia (oxygen depletion) and its extent in estuaries and coastal waters will increase. Global climate changes will likely result in higher water temperatures, stronger stratification, and increased inflows of freshwater and nutrients to coastal waters in many areas of the globe. Both past …


Tidal Sediment Yield Estimate Methodology In Virginia For The Chesapeake Bay Program Water Quality Model, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Julie Herman Jun 2009

Tidal Sediment Yield Estimate Methodology In Virginia For The Chesapeake Bay Program Water Quality Model, C. Scott Hardaway Jr., Donna A. Milligan, Lyle M. Varnell, Julie Herman

Reports

Water quality in Chesapeake Bay has degraded over the past 50 years with respect to oxygen depletion and reduced light attenuation. While the causes are numerous, sediment resuspension from wave and tidal action cloud the water column and reduce light attenuation thereby negatively affecting submerged aquatic vegetation (SAV) beds. Sediments on the Bay bottom come from upland runoff and shoreline erosion, each of which has significant contributions to the loading of sediments into estuary. The purpose of this report is to assess the present methods used to calculate sediment loading from tidal shoreline erosion that is input to the Chesapeake …


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 May 2009

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 …

Mathews County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Harry Berquist, Sharon Killeen, Carl Hershner, Tamia Rudnicky, Daniel E. Schatt, Karinna Nunez, Karen Reay, David Weiss

Reports

The data inventory developed for the Shoreline Situation Reports are based on a three-tiered shoreline assessment approach. This assessment characterizes conditions in the shorezone observed from a small boat moving along the shoreline. Handheld GPS units record data observations in the field. The three tiered shoreline assessment approach divides the shorezone into three regions:

  1. the immediate riparian zone, evaluated for land use

  2. the bank, evaluated for height, stability and natural protection

  3. the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

Three GIS coverages are generated from the collection technique. The Mathews_lubc coverage are features related …


Encroachment Of Sills Onto State-Owned Bottom: Design Guidelines For Chesapeake Bay, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine A. Wilcox, Jian Shen, Carl H. Hobbs Iii Mar 2009

Encroachment Of Sills Onto State-Owned Bottom: Design Guidelines For Chesapeake Bay, C. Scott Hardaway Jr., Donna A. Milligan, Kevin O'Brien, Christine A. Wilcox, Jian Shen, Carl H. Hobbs Iii

Reports

Recent efforts have sought to expand the use of “Living Shorelines” by waterfront property owners in Virginia and Maryland to combat tidal shoreline erosion. 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. Some regulatory agencies and non-governmental organizations prefer living shorelines over “traditional” shore hardening using bulkheads or stone revetments because these structures create a “barrier” or disconnect between the upland and marine environments. Typically, creation of a living shoreline involves the placement of sand, planting marsh flora, and, if necessary, …


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 …

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science Jan 2009

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

This study classified tidal wetlands for the Lynnhaven Watershed using remote sensing techniques and high resolution imagery from 2007. This updated delineation of wetlands, was used in conjunction with a simplistic geospatial elevation model to quantify the potential loss of wetlands under various sea level rise scenarios.The study revealed that using conservative estimates of sea level rise, nearly all wetlands would be lost by the year 2100. Projecting sea level rise into the future can be considered speculative, nevertheless such predictions are necessary to begin managing for and planning for climate change impacts. Evidence from this study suggests that upland …
