Dye tracing experiments are an active, effective and promising approach to investigate karst aquifers. In this paper, we develop a simple diagnostic model for calculating total recharge of sinks using dye tracing results. The conceptual model is that all sinks are conve...

Slunjska uravnava je del kordunskega krasa. Ta se razteza v nad. vis. 300-350 m, od najdlje proti zahodu segajocega dela doline Une do sotocja Slunjcice in Korane. Dolga je 40 in povprecno 10 km siroka. Vecji del te uravnave, zgrajene iz jurskih in krednih karbonatnih k...

This paper re-evaluates the karst phenomenon in Turkey basing on the controlling factors such as, the source of energy gradient, lithostratigraphy, type of erosion base and climate. Two major karst types described are a) evolutionary karst which implies continuous karst...

In the last two decades, Brazil has advanced in the creation of Natural Protected Areas (NPAs), reaching more than 17% of its territory. However, the budget allocated for the effectiveness of NPAs is still insufficient, creating gaps that hinder these areas from fulfill...

Na podlagi izsledkov starejsih raziskav je bil zahodni del pogorja Mecsek vkljucen v naravni park Donava - Drava. Zato je bilo treba raziskati tudi prsti in rastlinstvo. Raziskave prsti so bile usmerjene predvsem v dolocanje pH in merjenje vsebnosti kalcija. To je pomem...

We studied the environmental impact of wastes derived from calcium carbide, which is widely used for generating acetylene in industry and speleology. It was shown that spent carbide is toxic for biota and harmful to cave ecosystems and the surrounding environment. The t...

Anisotropy and heterogeneity of karstified rocks make them the most problematic media for various interventions which are needed in engineering practice. The long history of attempts to adapt karstic nature to human needs started with the utilization of karstic aquifers...

Epikarst is a weathered zone of enhanced porosity on or near the surface or at the soil/bedrock contact of many karst landscapes. The epikarst is essentially the upper boundary of a karst system but is also a reaction chamber where many organics accumulate and react wit...

Paleokarst shafts in the western desert of Egypt: A unique landscapeThe Eocene limestone plateau of the Western Desert of Egypt has various karst features, including shafts created during ancient wet periods. These Paleokarst shafts have been investigated on the plateau...

The most conspicuous six examples illustrating ascending (perascensum) speleogenesis linked with deep faults/fault systemswere selected from Slovakia and Czech Republic. In the past,the caves have been described as product of phreatic, epiphreaticand vadose speleogenesi...
