Virginia Beach, is experiencing more frequent flooding due to sea level rise, increased storm intensity, and aging infrastructure. These issues coupled with tidal impacts and low elevations has resulted in severe flooding in portions of the City. Hurricane Matthew (2016) resulted in the worst structural flooding ever experienced. As a result, the City embarked upon […]
As climate change, severe weather and Chesapeake Bay water quality standards increase in Virginia, stream restoration has been applied by localities, communities and environmental programs to meet ecological, mitigation and stormwater management goals. Stream restoration can be like open heart surgery to an ecosystem – intense, costly, yet potentially life-saving. Therefore, the proper selection of […]
The Chesapeake Bay Program, through its Maintain Healthy Watersheds Goal Implementation Team, works with state partners towards a goal of maintaining the long-term health of watersheds identified as healthy by each of the individual jurisdictions. Quantitative indicators are important to assess current watershed condition, track future condition, and assess the vulnerability of healthy watersheds to […]
Due to the increasing cost of stormwater treatment, the City of Virginia Beach Department of Public Utilities (City) evaluated the requirements for developing a nutrient offset program. When a stormwater management facility (SWMF) can be incorporated into a site design, it typically comes at a significant cost. Creating regional SWMFs to offset the City’s facility […]
A rising concern to lake and reservoir water quality is pharmaceuticals and personal care products (PPCPs), which are increasingly ubiquitous in the environment. Many studies have examined the introduction of PPCPs to freshwater ecosystems through wastewater treatment, but less is known about how direct human interactions, such as swimming, may influence PPCP concentrations. We sampled […]
The James River Treatment Plant (JRTP), Newport News, VA situates at the mouth of the Warwick River, a partially mixed estuarine tributary of the James River. Objectives of this study are to characterize mixing, transport and flux of total phosphorus (TP) loading from the JRTP’s effluent discharge in the estuarine cove of Warwick River, and […]
Under the U.S EPA’s Chesapeake Bay Total Maximum Daily Load (TMDL) established in 2010 to restore and protect the bay, many state and local entities are required to implement changes in their processes to lower both Point Source (PS) and Non-Point Source (NPS) loading contributions. In this study, effect of a PS loading modification from […]
The Lynnhaven River in the City of Virginia Beach is a waterway of national significance and was once renowned for its oyster population. For decades, the river had been impaired to a point where oysters and other fish caught could not be consumed. Through regional efforts, the river is rebounding. The LRBER Project is an […]
Accumulated sediments located in waterways require comprehensive characterization prior to removal to facilitate the selection of suitable disposal sites and minimize impacts to project schedule and budget. Sediments often contain a variety of environmental contaminants above regulated concentrations. The deposition process can concentrate heavy contaminants such as metals and create an anerobic environment that can […]
Despite increasing numbers of agricultural best management practices (BMPs) on the landscape and billions of dollars spent on BMP programs, stream health continues to decline in Virginia due to agricultural nonpoint-source pollution. The efficacy of BMPs for restoring stream health is potentially enhanced or constrained by conditions in the stream and watershed, as well as […]
The Virginia Lakes and Watershed Association is a volunteer organization and its mission is to provide education on water resources in Virginia.
