Abstract Rull cave is a karstic located in Vall d’Ebo (Alicante, Southeast of Spain) developed massive Miocene conglomerates and Cretaceous limestones. Processes soil above outdoor atmosphere directly influence the underground environment cave. Continuous discrete monitoring (from 2012 to 2022) allows characterise spatial distribution temporal variations gaseous concentration ( 222 Rn CO 2 ) un...

The soils and underlying weathered carbonate rock in karstic regions play an important role the infiltration, storage, retention of water nutrients. Because significant heterogeneity karst, use individual geophysical techniques is often not sufficient for unambiguous assessment irregular distributions fractures. In this study, ground penetrating radar (GPR) electrical resistivity tomography (ER...

Important karstic aquifers exist in west and southwest of Iran. Mansour-Abad Karstic region is located in Shiraz, southwest of Iran. It supplies the drinking water for the whole area by 4 pumping water wells, some of which have water turbidity problem. The present research aims to assess the hydrogeochemistry and turbidity problem in the karstic water production wells. The EC varies between 703...

Microaerophilic Fe(II)-oxidizing bacteria are often chemolithoautotrophs, and the Fe(III) (oxyhydr)oxides they form could immobilize arsenic (As). If such microbes active in karstic paddy soils, their activity would help increase soil organic carbon mitigate As contamination. We therefore used gel-stabilized gradient systems to cultivate microaerophilic from investigate capacity for Fe(II) oxid...

We assess the errors produced by considering temperature as a conservative tracer in fluviokarst studies. Heat transfer that occurs between karstic Conduit System (CS) and Porous Fractured Matrix (PFM) is the reason why one should be careful in making this assumption without caution. We consider the karstic aquifer as an Open Thermodynamic System (OTS), which boundaries are permeable to thermal...

Seasonal dynamics of naturally occurring prokaryotes, viruses, and heterotrophic nanoflagellates in two hydro-geologically contrasting alpine karst springs were monitored over three annual cycles. To our knowledge, this study is the first to shed light on the occurrence and possible interrelationships between these three groups in karstic groundwater. Hydrological and microbiological standard i...

Five karstification phases are recognized and analysed in the Mesozoic carbonate sequences of the External and Internal Subbetic (Betic Cordilleras, southern Spain). These phases are related to important stratigraphic discontinuities in the following ages: (1) Intra-Carixian, (2) Early–Middle Jurassic boundary, (3) late Bathonian–early Callovian, (4) Intra-Kimmeridgian, and (6) late Albian. The...
