1 Introduction. Karst regions cover 7–12% of the Earth''s continental area, and their aquifers are at least a partial source of drinking water supply to almost a quarter of the world''s population [Ford and Williams, 2007].Stress on groundwater resources has increased significantly in recent decades [Wada et al., 2010], (1) in terms of water

The heterogeneity of karst systems, which affects contaminant transport, storage, and reactivity, leads to highly variable spatial input of these contaminants into the aquifer. Particulate matter and sediment and attached organic contaminants, nutrients, or bacteria can be stored and rapidly transported through karst aquifers as a result of rapid
For the physical sandbox karst aquifer, the geostatistics-based HT yielded both the hydraulic conductivity (Fig. 2 a) and the specific storage field (Fig. 3 b), while the travel time-based HT also yielded the hydraulic diffusivity (Fig. 2 b) and the specific storage field (Fig. 4 b), after applying the mask of null-space energy (for the un
There are a number of ways that the study of karst landscapes intersects with sustainability assessments. Karst should be considered when measuring the sustainability of energy resources, water supply, building materials, agricultural and food practices, land preservation and management, tourism, and greenhouse gas management.

Karst aquifers—formed when the movement of water dissolves bedrock—are critical groundwater resources in North America. Water moving through these aquifers carves out magnificent caves, sinkholes, and other formations. These formations are home to high concentrations of rare and endangered species, but the hydrological
Woody plants are encroaching into grasslands and savannas of the karst Edwards Plateau, but their impacts on climate and hydrology are unclear because of high variability in soil depth and uncertainties about the contribution of water in fractured limestone to the water available to trees.

1. Introduction. Karst water is an important freshwater source for millions of people worldwide, providing groundwater for drinking, irrigation, industrial uses and ecosystems (Bakalowicz, 2005, Koit et al., 2022, Goldscheider et al., 2020).However, the complex matrix–conduit systems that characterize karst aquifers make it challenging to

1. Introduction. The carbonate karst geothermal reservoir, with a great potential for the development and utilization of geothermal energy in China, is characterized by the large water production and easy reinjection of geothermal tailwater [1].The total distribution area of these geothermal reservoirs accounts for 33% of the land area in
Therefore, in this paper, we investigated the effects of karst matrix hydrogeological parameters on the estimation accuracy of karstic water storage variation using a numerical modelling approach. Specifically, we considered matrix–conduit coupled karst systems and analysed the spring flow recession hydrograph following rainfall events.
Temperature, discharge, and stable isotope ratios of five karst springs in a mountainous area of Zigui County, Hubei Province, Central China, were analyzed. The purpose was to illustrate the heat exchanges linked to circulation depth in the exposed karst water systems through the development of a method for estimating heat input and heat
