Living Shoreline Sea-Level Resiliency: Performance And Adaptive Management Of Existing Sites, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox
Living Shoreline Sea-Level Resiliency: Performance And Adaptive Management Of Existing Sites, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox
Reports
The goal of this project is to monitor effectiveness of nature-based resiliency projects such as those that use living shoreline management strategies. Living shoreline strategies can effectively control shoreline erosion while providing water quality benefits and maintaining natural habitat and coastal processes. These ecosystem-based management systems have been the preferred alternative for stabilizing tidal shorelines in the Commonwealth of Virginia since 2011. However, a recent analysis has shown that between 2011 and 2016 only 24% of the permits granted for shore protection were considered living shorelines (ASMFC, 2016). These types of systems may be relatively new to many landowners and …

Targeted Living Shoreline Management Planning For Virginia State Parks In Chesapeake Bay Summary Report, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox
Reports
The Commonwealth of Virginia owns numerous tidal, waterfront properties along Chesapeake Bay and its tributaries including state parks, natural area preserves, and wildlife management areas. Many of these parks have eroding shorelines and are at risk from coastal hazards such as tidal flooding, waves, and sea level rise. These environmental threats impact the safety of park visitors and the mission of the parks.
In an effort to address these issues for the parks as well as provide education to the public on living shoreline management strategies, eleven state parks with tidal shoreline along the Chesapeake Bay and its tributaries were …
Oyster Bag Sill Construction And Monitoring At Two Sites In Chesapeake Bay, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox, Walter I. Priest
Oyster Bag Sill Construction And Monitoring At Two Sites In Chesapeake Bay, Donna A. Milligan, C. Scott Hardaway Jr., Christine A. Wilcox, Walter I. Priest
Reports
The use of oyster shell bags as a means of shore protection along fetchlimited shorelines in Chesapeake Bay is growing. This method is an innovative use of a byproduct of the seafood industry and can provide habitat creation, water quality improvement, and shore protection. The landowner can install the bags themselves, and with the new living shoreline general permit in Virginia, these projects are easier than ever to afford and install. However, oyster shells are a limited resource that are needed for largescale oyster reef restoration with the Chesapeake Bay watershed, so determining the effectiveness of this shore protection strategy …

An Updated Model For Estimating The Tmdl-Related Benefits Of Oyster Reef Restoration Harris Creek, Maryland, Usa, M. Lisa Kellogg, Mark J. Brush, Jeff C. Cornwell
Reports
In 2014, a user-friendly, web-accessible model was developed that allowed restoration practitioners and resource managers to easily estimate the TMDLrelated benefits of oyster reef (Crassostrea virginica) restoration per unit area, run restoration scenarios in Harris Creek, MD to optimize restoration planning and implementation, and calculate the benefits of the chosen plan. The model was rooted in scientifically defensible data and was readily transferrable to systems throughout the Chesapeake Bay and Eastern Shore. The model operated in five vertically well-mixed boxes along the main axis of the creek. Exchanges among creeks were computed using a tidal prism approach and were compared …

Simple Parameterized Models For Predicting Mobility, Burial And Re-Exposure Of Underwater Munitions. Serdp Final Report Mr-2224, Carl Friedrichs, Sarah E. Rennie, Alan Brandt
Reports
A compilation of 761 observations of scour-induced burial and 406 observations of initiation of motion of UXO-like objects are presented. The main factors that increase the scour-induced burial-to-diameter ratio (B/D) under (i) currents and (ii) waves are the (i) Shields parameter (S) and (ii) Keulegan-Carpenter number. For cylinders under waves, B/D additionally increases as the current component parallel to wave orbitals decreases, as S increases, and as the angle between wave orbitals and a cylinder’s axis increases. Cylinders bury most, then spheres, and conical frustums bury least. Simple models dependent on these variables explain 85% of observed variance in B/D. …

Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2017 Annual Report, Eric J. Hilton, Rob Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee
Reports
This report describes the results of the twentieth year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2017, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs, one using staked gillnets in the Rappahannock River (year 2) and the other using anchor gillnets in the Chickahominy River (year 3; a major tributary of the James River),to determine relative abundance and stock structure for the …
Virginia Seafood Sustainability, Robert A. Fisher
Virginia Seafood Sustainability, Robert A. Fisher
Reports
Virginia’s commercial fisheries operate sustainably under a suite of management tools based upon information received from marine scientists and fishery managers who regularly conduct biological sampling of fish while tracking commercial landings and other gathering of required information. Analyses of fishing effort and overall stock conditions, as well as formulas designed to calculate threshold limits for maintaining sustainable stocks are regularly performed. Restrictions on seasons, size, days at sea, and gear are imposed as needed to achieve management supporting long-term biological sustainability.

Anthropocene Sea Level Change: A History Of Recent Trends Observed In The U.S. East, Gulf, And West Coast Regions, John D. Boon, Molly Mitchell, Jon Derek Loftis, David L. Malmquist
Reports
Relative sea level (RSL) observations since 1969 at U.S. tide stations exhibit trends in RSL rise rate and acceleration that vary in response to both global and regional processes. Trend histories display a high degree of similarity between locations in coastal regions that are experiencing similar processes. With the exception of the U.S. Northeast Coast and Alaska,every other coastal location in the continental U.S. has experienced an upturn in RSL rise rate since 2013-2014 despite wide differences in the magnitude and trending direction of RSL acceleration. High RSL acceleration along the U.S. Northeast Coast has trended downward since 2011 while …
