Hampton Roads Benchmark Monitoring Network

The southern Chesapeake Bay region is experiencing land subsidence along with rising sea levels, both of which can contribute to coastal flooding. The rates at which these two processes are occurring are not exactly known. Mapping of land elevation change requires ground-truth survey data at multiple locations that are accurate and precise. With the exception of a few CORS sites that have...

Improving Time of Concentration Estimates for Small Rural Watersheds in the Appalachian Plateaus Physiographic Province, West Virginia

Many culverts and other drainage structures in rural West Virginia are located in small streams or valleys draining 100 acres or less. Design of these structures in West Virginia is generally done using discharge estimates made with widely used and well accepted methods. However, these methods require information including flow-segment length and channel geometry that are poorly characterized...

Climate Change in the Chesapeake Bay Watershed: Effects on Riverine Discharge, Ecosystems, and Water Quality

The 64,000-square mile watershed that drains to the Chesapeake Bay is highly populated and has diverse land use, including forested, agricultural, and urbanized areas. Increased precipitation in the eastern United States over the last 100 years has affected stream flow and thus the loading of pollutants delivered to the bay. Such pollutants as suspended sediment and dissolved phosphorus and...

USGS-VDOT Bridge Scour Pilot Study

Cost effective and safe highway bridge designs are required to ensure the long-term sustainability of Virginia’s road systems. The water flows that, over time, scour streambed sediments from bridge piers inherently affect bridge safety and design costs. To ensure safety, bridge designs must anticipate streambed scour at bridge piers over the lifespan of a bridge. Until recently Federal Highway...

GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...

Post-Hurricane Sandy Vegetation Recovery in the Presence of a Hyper-abundant Deer Population

The Challenge: The primary dune along barrier island beaches protects leeward vegetation from tidal fluctuation, salt spray and storm surge.  However, storm surges like those experienced during Hurricane Sandy can obliterate the primary dune, transporting sand inland and burying existing vegetation.  The dune rebuilds naturally as recovering vegetation traps wind-blown and waterborne sand. ...

DNA Barcoding for Identifying Native Bee Species

The Challenge: Traditionally, bee identification has relied on taxonomic methods centered on descriptions of morphological differences between species.

The lack of distinguishing morphological characters useful for separating closely...

Assessing Toxicogenomics Effects of a Synthetic Androgen on Japanese Quail and the Development of an Avian Vitellogenesis Model

The Challenge: Endocrine active chemicals (EAC) are known to interfere with hormonally regulated physiological processes, thereby affecting signaling in the hypothalamic-pituitary-gonadal-liver (HPGL) axis and commonly resulting in reproductive dysfunction. Computational models that relate hormonal and genomic biomarkers within the HPGL axis to the reproductive cycle and ecologically relevant...

The Role of Japanese Quail in Ecotoxicology

The Challenge: Wild birds are exposed throughout their lives to natural and synthetic chemicals that are present in the environment, many of which interfere with the animal’s physiological and developmental systems. Relative concentrations, routes, frequency, and the environment in which chemical exposure occurs will determine to a large extent the bird’s response. Well-designed avian field...
