Water flow characteristics of Maocun underground river basin based on environmental isotopes
Carsologica Sinica, 2022 Underground river basins in peak-cluster depressions are main water supply sources of villages in Guangxi. But there exist problems of groundwater exploitation, groundwater pollution and natural disasters in these areas due to a special geological ...

Deep Underground Science and Engineering, EarlyView.To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Association of runoff risk with private well contamination in a fractured dolostone aquifer. [PDF]
J Environ QualAbstract In the United States, private well owners are responsible for monitoring and maintaining their drinking water but have little control over neighboring contamination sources and limited information about daily water quality. Potential for rapid contamination in karst settings exacerbates the challenge.

The hydrogeology of bromate contamination in the Hertfordshire Chalk: incorporating karst in predictive models [PDF]
, 2010 Point source contamination of groundwater by bromate (BrO3^-) in the Hertfordshire Chalk Aquifer forced the closure in 2000, of a major public supply ground- water abstraction and presents a continuing threat to regional water resources.

Energy Science &Engineering, EarlyView.This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.
