ISBN-13: 9783319212029

This e-book specializes in the outlet and exploration of greater than 350 formerly undiscovered caves of the Slovenian Karst, stumbled on in the course of highway development paintings. The summarizes the making plans of site visitors roads and provides the hot findings bought in the course of building, in addition to stories on newly-discovered karst phenomena and karst waters and their protection.

Earthmoving paintings in the course of development has published a cross-section of the outside of the Classical Karst, coated karst with recognized underground stone forests and specified karst in breccia. examine carried out in those caves has yielded a few new findings on how the karst floor and underground have been shaped, at the stream of water via karst aquifers, and at the evolution of karst on a variety of sorts of rock and below a variety of stipulations. The paintings used to be written via researchers from the ZRC SAZU Karst examine Institute and the Institute of Geology AS CR. The reader will enjoy the authors’ collaboration with planners and developers, which bargains necessary insights for the making plans and execution in their personal actions in karst areas.

Plankton serves as an excellent instrument for measuring water caliber. Many neighborhood councils and water caliber managers gather phytoplankton and zooplankton according to the expanding occurrence of algal (phytoplankton) blooms in rivers and estuaries; in spite of the fact that, an absence of consistency and clinical rigor within the methodologies used frequently ends up in unresolved results.

10 An old shaft filled with fine-grained alluvium Cave Preservation All the caves discovered during the motorway construction were measured, mapped out (Fig. 11) and explored. Supported by road builders, we tried to preserve as many as possible. Now they are hidden behind rock embankments at the edges of respective roadcuts, and behind concrete rims inside the tunnel. Caves located under the road, with narrower openings and, despite blasting, a relatively unfractured rock rim, were covered with concrete slabs.

Near the Kozina motorway exit, we discovered completely black flowstone of a smaller scale; it was partially weathered and non-homogeneous. It contained a large amount of non-carbonate inclusions. A significant portion of yellow-grey cave sediment was also found in a larger flowstone deposit in the cave close by. The basic structure of the flowstone was not weathered. Subsequently, cave sediment filled the space in the otherwise highly porous flowstone. North of the motel near Kozina, still in the northern section of the route, a highly homogenous and compact bed of orange-brown flowstone was found when drilling.

Those that were filled with fine-grained deposits had supra-alluvial scallops along their rim. 3 Discovered Caves 25 Fig. 5 The wall of the passage that has formed along the alluvium, with the passage being filled with fine-grained alluvium Fig. 6 Alluvia in an unroofed cave In addition, there was a shaft with a diameter of 4 m located within the perimeter of the described cave system, before the tunnel (Fig. 10). It was completely filled with fine-grained alluvium. Its walls showed traces of percolating water and were only occasionally reshaped under the alluvium.
