Rock mass classification systems are used to categorize and estimate the role of the most
significant parameters influencing rock mass behavior to represent an equivalent continuum …

Measured concentrations of environmental tracers in spring discharge from a karst aquifer in
the Shenandoah Valley, USA, were used to refine a numerical groundwater flow model. The …

Synthesis of rock-core sampling and chlorinated volatile organic compound (CVOC)
analysis at five coreholes, with hydraulic and water-quality monitoring and a detailed …

A new method was developed for conducting aquifer tests in fractured‐rock flow systems
that have a pump‐and‐treat (P&T) operation for containing and removing groundwater …

Groundwater flow is influenced by topography, but in fractured and dipping sedimentary
rocks, it is also influenced by structure. Field evidence indicates that groundwater is older on …

A numerical representation that explicitly represents the generalized three-dimensional
anisotropy of folded fractured-sedimentary rocks in a groundwater model best reproduces …

The growth of human population often corresponds with change in land use, including
expansion of urban areas, which necessitates increasing the available amount of drinking …

Abstract The US Geological Survey (USGS) collected data on the vertical distribution of
hydraulic head, specific capacity, and water quality using aquifer-interval-isolation tests and …

Abstract The US Geological Survey (USGS) conducted hydrogeologic investigations,
reviewed existing data, and developed a preliminary conceptual model of the groundwater …
