Mathematical Modeling of Karst Aquifers

2015
The chapter presents an overview of numerical modeling techniques for equivalent porous media (EPM) and conduit flow formulations, including a case study illustrating the value of conduit presentation. The authors provide an overview of basic numerical modeling concepts, including layering and the assignment of boundary conditions.

Karst: Environment and Management of Aquifers

Karst comprises complex systems of soluble rocks and water forming a surface and underground environment with rich but vulnerable aquifer systems that produce the world’s largest proportion of pristine water. The interactions of soluble rocks and water create landscapes and subsurface forms that are not found in any other rock or aquifer.

Estimating potential for exploitation of karst aquifer: case example on two Serbian karst aquifer

Environmental Earth Sciences, 2013
Rational use of karst water resources depends considerably on the existence of a successful approach to estimating karst groundwater potential for exploitation. The term groundwater potential for exploitation involves the application of regulatory measures affecting natural outflow regime.

Is the Term ‘Karst Aquifer’ Misleading?

2010
Carbonate rock sequences commonly provide significant quantities of groundwater but the term ‘aquifer’ is potentially misleading when applied to these sequences because, in common usage, it implies a single body of groundwater in which water moves down a hydraulic gradient towards a specific surface outlet.

Karst Aquifers: Hydrogeology and Exploitation

2008
Karstic terrains cover approximately 12% of the Earth’s continental surface and 25% of the world’s population is supplied partially or entirely by karst water resources. In the Mediterranean and Southeast Asia, karst aquifers are the primary water resources.

Influence of the karst spring submergence on the karst aquifer regime

Journal of Hydrology, 1986
Abstract With the construction of a 123 m high dam, a large and permanent karst spring was flooded by water, about 75 m deep. The annual average discharge of this zone is 80 m 3 s −1 . The aquifer zone which discharges through this spring was formed under complex tectogenetic conditions of Dinaric karst. The most prominent structures are overthrusts

Protection of Karst Aquifers in Istria

2007
With its population of 206, 344 inhabitants and at least three times more tourists during the summer period, Istria is supplied with potable water from the Istrian karst aquifers. Karst aquifers are highly susceptible to human impact because the water is retained in the underground for short periods of time and contact surfaces between water and rocks ...

Investigating the hydrological behaviour of a shallow karst aquifer flooding intermittently: the Pivka Karst Aquifer (Slovenia)

The Pivka Karst Aquifer is a shallow karst aquifer located under the Upper Pivka Valley, about 40 km SW from Ljubljana (Slovenia). This aquifer is connected to the larger Javorniki Karst Aquifer that borders the Upper Pivka Valley on the NE. While the geometry of the conduit system in the Pivka Karst Aquifer is practically unknown, the geometry of the ...
