Karst Groundwater Vulnerability Determined by Modeled Age and Residence Time Tracers
Geophysical Research Letters, 2023 Karst aquifers are a vital groundwater resource globally, but features such as rapid recharge and conduit flow make them highly vulnerable to land‐surface contamination.

Acta Carsologica, 2010 Lithostratigraphy and geologic structures are major controls on groundwater flow in alpine karst systems. Understanding these factors is important for the delimitation of drinking water protection zones. The Winterstaude mountain chain, western Austria,

Karst Water Management in Slovenia in the Frame of Vulnerability Mapping
Acta Carsologica, 2006 Slovene karst sources are of great national importance for drinking water supply. Since karst aquifer systems are very susceptible to contamination, these sources require appropriate and careful managing. Unfortunately, in the acts of Slovene legislation,

Impact of connected conduit on pumping-induced seawater intrusion in a coastal karst aquifer
Frontiers in Marine Science, 2023 IntroductionCoastal karst aquifers face the risk of seawater intrusion due to groundwater development. Based on the conceptualization of Woodville Karst Plain (WKP), this study investigates the effect of karst conduit and pumping conditions on the ...

Karst Aquifer evolution in fractured, porous rocks [PDF]
Water Resources Research, 2000 The evolution of flow in a fractured, porous karst aquifer is studied by means of the finite element method on a two‐dimensional mesh of irregularly spaced nodal points. Flow within the karst aquifer is driven by surface recharge from the entire region, simulating a precipitation pattern, and is directed toward an entrenched river as a base level ...

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 ...

Energy Science &Engineering, EarlyView.This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou
