That chalk is 1. used as a proper noun chalk describes a rock unit of cretaceous age, that consists predominately of relatively soft, white, porous limestone with beds of marl and bands or nodules of flint. the term is used without its initial capital to describe any rock with similar appearance and properties. generally chalk has a relatively high primary permeability and so rarely develops caves of explorable size, though conduit-water flow does occur. some harder chalks in northern france and south-eastern england hold explorable active and relict caves, which extend for many hundreds of meters [9]. 2. soft poorly indurated limestone, generally light in color; commonly composed of the tests of floating microorganisms in a matrix of very finely crystalline calcite [10].?

Surface and Groundwater Interaction of the Bela Stream and Vipava Springs in Southwestern Slovenia
Abstract:

Previous studies suggest a hydrogeologic link between the Vipava springs and the neighbouring Bela surface stream. The Vipava springs drain the Nanos karst plateau. The Bela stream drains the very low permeable flysch to the north west of the Nanos plateau before flowing onto limestone where it gradually sinks along its course. A tracer, uranine, was injected into the Bela upstream of the village Vrhpolje and hydraulic connection with all the Vipava springs was proved. A dispersion model was used to characterise the tracer breakthrough curve of one of the springs where the highest concentrations were found. The hydrology of the Bela was analysed by measuring the discharge of the stream at 8 different sections and analysing the difference in flow between each section. The conclusion drawn from the analysis was that the Bela stream has a different hydrological response related to whether the majority of recharge comes from the karstic or flysch area of the catchment. A flow separation analysis based on hydrochemical measurements indicated that the hydrological response of the Vipava springs also depends on the recharge source area. Proved connection leads to environmental concern for the water quality of the Vipava springs, which are the main water supply of the area, because untreated wastewater is discharged into the Bela stream.
