Application of short time series analysis for the hydrodynamic characterization of a coastal karst aquifer: the Salento aquifer (Southern Italy)

open access: yesJournal of Hydroinformatics, 2022
Daily precipitation and groundwater level data, registered at 7 rain gauge stations and 11 monitoring wells in the Salento coastal karst aquifer (Southern Italy) were subject to short time series analyses to evaluate the hydrodynamic response of the ...

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.

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.

Hydrodynamic modeling of a complex karst-alluvial aquifer: case study of Prijedor Groundwater Source, Republic of Srpska, Bosnia and Herzegovina

open access: yesActa Carsologica, 2013
Middle Triassic fractured and karstified limestone and dolomite form a karst aquifer in the Sana River Valley near the town of Prijedor. As a result of intensive tectonic movements, carbonate rocks are mostly below the Sana River level, covered by ...

A lumped parameter model to evaluate the relevance of excess air as a tracer of exchanged flows between transmissive and capacitive compartments of karst systems

open access: yesFrontiers in Water, 2022
The objective of this study was to evaluate the relevance of using excess air (EA) for the characterization of drain/matrix exchange in karst systems using a rainfall discharge model coupled with the simulation of EA measured at the outlet of the studied
