Living Shoreline Sea Level Resiliency: Performance And Adaptive Management Of Existing Breakwater Sites, Year 2 Summary Report, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Angela C. Milligan Nov 2019

Living Shoreline Sea Level Resiliency: Performance And Adaptive Management Of Existing Breakwater Sites, Year 2 Summary Report, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Angela C. Milligan

Reports

The Coastal Zone Management program, through NOAA grants, has funded several projects that have reviewed design considerations and monitored living shoreline systems for effectiveness at both shore protection and habitat enhancement. These studies presented data regarding the construction and performance of three living shoreline projects that were built between 1999 and 2003 in Maryland (Hardaway et al., 2007 and 2009) and were in part the basis for the “Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments” and the contractor training classes (Hardaway et al., 2017). In addition, extensive research has been done on the design and performance …


Spatiotemporal Downscaling Rainfall Predictions Of North American Regional Climate Change Assessment Program For Entire Virginia, Zhaoyi Cai Oct 2019

Spatiotemporal Downscaling Rainfall Predictions Of North American Regional Climate Change Assessment Program For Entire Virginia, Zhaoyi Cai

Civil & Environmental Engineering Theses & Dissertations

This thesis developed a statistical downscaling approach, which consists of a series of linear regression equations, to spatiotemporally downscale the rainfall predictions from North American Regional Climate Change Assessment Program (NARCCAP) in accordance with the 15-min observed rainfall data at the rain gauges across the state of Virginia. NARCCAP has generated twelve different region-global climate models (RCM-GCMs) with a temporal resolution of 3 hr and a spatial resolution of 50 km over the entire America. Although it has been downscaled already, such resolutions are still too coarse to represent the rain gauges. This means that the RCM-GCMs’ predictions need to …


Living Shorelines: Barriers And Promotion: Accomack County, Va, Amy Belcher, Rhiannon Bezore, Michelle Covi, Wie Yusuf Sep 2019

Living Shorelines: Barriers And Promotion: Accomack County, Va, Amy Belcher, Rhiannon Bezore, Michelle Covi, Wie Yusuf

Presentations, Lectures, Posters, Reports

Living shorelines can offer shoreline protection for low energy shorelines as well as providing ecoservices such as purifying water, buffering against floods, and attracting wildlife. This report highlights key benefits, possible barriers and solutions, and ideas for their promotion. Recommendations for implementing living shorelines are included for Accomack County, Virginia to aid in increasing awareness and utilization of living shorelines.


Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2018 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee Apr 2019

Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2018 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee

Reports

This report describes the results of the twenty-first 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 2018, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs using anchor gillnets in the Rappahannock River (year 1) and the Chickahominy River (year 4; a major tributary of the James River), to determine relative abundance and stock structure for the adult spawning run of river herring …

[from Background and Overview]

Communities in coastal Virginia, particularly in the urban region of Hampton Roads and the rural Eastern Shore peninsula, are experiencing the impacts of climate change as part of everyday life. Among the most apparent impacts are sea level rise and associated flooding, but increasingly residents of the region are observing changing ecosystems, health impacts and complex social challenges are made more difficult. The region is experiencing the fastest rate of relative sea level rise on the U.S. east coast due to interactions between ocean currents, global sea level rise, high-water tables and ground subsidence (Adapt Virginia …


Precipitation Trends Across The Commonwealth Of Virginia (1947 – 2016), Michael J. Allen, Thomas R. Allen Apr 2019

Precipitation Trends Across The Commonwealth Of Virginia (1947 – 2016), Michael J. Allen, Thomas R. Allen

Virginia Journal of Science

Water is an important resource for the Commonwealth of Virginia. Too much water increases runoff, disrupt transportation networks, and contributes to school closures. Too little water may adversely impact agricultural operations. To improve climate-related information to Virginia citizens, this study assesses means and changes in precipitation across the Commonwealth of Virginia (1947 – 2016). Using daily station-level precipitation data from the Global Historical Climate Network (GHCN), descriptive statistics were calculated for 43 locations in terms of total precipitation (inches decade-1), precipitation days (x>0”), and heavy precipitation days (x>1.0”). On average, locations showed an overall increase in …


The Case For A Mandatory Renewable Portfolio Standard In Virginia: A Case Study Examining Virginia’S Potential For A Mandatory Renewable Portfolio Standard By Comparing Virginia To Maryland And North Carolina, Rebecca Wescott Mar 2019

The Case For A Mandatory Renewable Portfolio Standard In Virginia: A Case Study Examining Virginia’S Potential For A Mandatory Renewable Portfolio Standard By Comparing Virginia To Maryland And North Carolina, Rebecca Wescott

William & Mary Environmental Law and Policy Review

Since the early 1980s, states have utilized Renewable Energy Portfolio Standards (“RPSs”) as policy mechanisms to “promote broader investment in renewable energy without requiring passage of a comprehensive energy policy measure that includes a pricing mechanism for carbon.” RPS policies can be drafted in one of two ways: (1) as a mandatory RPS, a legal mandate on what percentage of a state’s power portfolio must come from specific eligible renewable energy sources by a specific date in the future, or (2) as a non-binding or voluntary RPS, a policy goal that recommends that a certain percentage of a state’s power …

Evaluation Of Private Landowner Intention To Create Early Successional Habitat In Virginia's Appalachian Region, Hannah M. Coovert Jan 2019

Evaluation Of Private Landowner Intention To Create Early Successional Habitat In Virginia's Appalachian Region, Hannah M. Coovert

Theses and Dissertations

As human land uses continue to expand rapidly across the landscape, the management practices of private landowners are an essential part of effective conservation of biodiversity. Conservation of early successional habitats (ESH) and the species that depend on them is a priority in the eastern United States, and efforts to create more ESH on private lands has primarily focused on forest landowners and the harvesting of timber. Private lands with significant pasture cover in a forested landscape present an additional opportunity to create and maintain ESH, yet our understanding of landowner values and attitudes about management strategies in pastures (i.e., …
