Virginia Beach Shallow Groundwater Study

The purpose of the Virginia Beach shallow aquifer study is to better understand the distribution of fresh groundwater, its susceptibility to contamination, and its sustainability as a long-term water supply. Virginia Beach is a growing city in southeastern Virginia with a limited supply of fresh water. Most of the city’s drinking water, up to 45 million gallons per day, comes from Lake Gaston...

Warren County Non-Carbonate Aquifer Appraisal

The non-carbonate aquifer system is present over an extensive region of the Northern Shenandoah Valley and is increasingly being relied upon to supply water to local communities. This is an area with an expanding economy and a growing population, and, to meet future water needs, this aquifer is likely to be developed to supplement current withdrawals from both the carbonate aquifer system and...

Bacteriological quality of groundwater used for household supply

In fractured bedrock aquifers used for domestic supply conditions can exist where contaminants such as bacteria are not filtered out by the soil. Once in the fracture system, little additional filtration takes place.

The results of a synotic sampling of domestic wells in the Lower Susquehanna River basin, Pennsylvania and Maryland, showed that bacteria concentrations were higher in...

National Highway Runoff Water-Quality Data and Methodology Synthesis (NDAMS)

Knowledge of the characteristics of highway runoff (concentrations and loads of constituents and the physical and chemical processes that produce this runoff) is important for decisionmakers, planners, and highway engineers to assess and mitigate possible adverse impacts of highway runoff on the Nation's receiving waters. This project was done by the U.S. Geological Survey (USGS) in...

Standardization and application of an index of community integrity for waterbirds in the Chesapeake Bay, USA

In recent decades, there has been increasing interest in the application of ecological indices to assess ecosystem condition in response to anthropogenic activities. An Index of Waterbird Community Integrity was previously developed for the Chesapeake Bay, USA. However, the scoring criteria were not defined well enough to generate scores for new...

Sensitivity of the downward to sweeping velocity ratio to the bypass flow percentage along a guide wall for downstream fish passage

Partial-depth impermeable guidance structures (or guide walls) are used as a method to assist in the downstream passage of fish at a hydroelectric facility. However, guide walls can result in a strong downward velocity causing the approaching fish to pass below the wall and into the direction of the turbine intakes. The objective of this study was...

Deep-sea coral research and technology program: Alaska deep-sea coral and sponge initiative final report

Deep-sea coral and sponge ecosystems are widespread throughout most of Alaska’s marine waters. In some places, such as the central and western Aleutian Islands, deep-sea coral and sponge resources can be extremely diverse and may rank among the most abundant deep-sea coral and sponge communities in the world. Many different species of fishes and...

Climate-driven variability in the occurrence of major floods across North America and Europe

Concern over the potential impact of anthropogenic climate change on flooding has led to a proliferation of studies examining past flood trends. Many studies have analysed annual-maximum flow trends but few have quantified changes in major (25–100 year return period) floods, i.e. those that have the greatest societal impacts. Existing major-...

Linkages and feedbacks in orogenic systems: An introduction

Orogenic processes operate at scales ranging from the lithosphere to grain-scale, and are inexorably linked. For example, in many orogens, fault and shear zone architecture controls distribution of heat advection along faults and also acts as the primary mechanism for redistribution of heat-producing material. This sets up the thermal structure of...

Taxonomic reassessment of bats from Castelnau’s expedition to South America (1843–1847): Phyllostoma angusticeps Gervais, 1856 (Chiroptera, Phyllostomidae)

Gervais, in 1856, described the bats collected during Castelnau’s expedition through South America (1843–1847). We report that Phyllostoma angusticeps (Gervais, 1856), long treated as a junior synonym of Phyllostomus discolor(Wagner, 1843), is not a representative of the genus Phyllostomus. In fact, as we demonstrate, it...
