Epikarst zone of a karst aquifer – its characteristics and importance in karst hydrogeology

open access: yesGeologija, 2002
The karst aquifer’s epikarst zone is a subject of the research. It is an important part of the aquifer, particularly from a hydrodynamic point of view.

Dynamics of water fluxes and storages in an Alpine karst catchment under current and potential future climate conditions [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Karst aquifers are difficult to manage due to their unique hydrogeological characteristics. Future climate projections suggest a strong change in temperature and precipitation regimes in European karst regions over the next decades.

Simplified approach in karst aquifer characterization by using discharge variability, storage capacity, and void development: A preliminary study in the tropical karst region

open access: yesKuwait Journal of Science, 2023
One of the main challenges in karst water management is the limited availability of measured hydrogeological data. This research aimed to employ a simplified approach for aquifer characterization by applying discharge variability, storage capacity, and ...

Estimated rate of karst aquifer development by MRC analysis and flood hydrograph components at Guntur Springs, Gunungsewu Karst Area, Indonesia [PDF]

open access: yesE3S Web of Conferences, 2020
Understanding the stage of karst aquifer development (karstification) is of vital importance because this parameter can reflect the character of flow system release, from which relevant management patterns are derived.

Process-based karst modelling to relate hydrodynamic and hydrochemical characteristics to system properties [PDF]

open access: yes, 2013
More than 30% of Europe's land surface is made up of karst exposures. In some countries, water from karst aquifers constitutes almost half of the drinking water supply.

Evolution Mechanism of Water-Conducting Channel of Collapse Column in Karst Mining Area of Southwest China

open access: yesGeofluids, 2021
There are many karst collapse columns in coal seam roof in the southern coal field in China, which are different from those in coal seam floor in the northern coal field, due to the stratum characteristics.
