In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...

Karst topography is a special landscape shaped by the dissolution of one or more layers of soluble bedrock, usually carbonate rock such as limestone or dolomite. Due to subterranean drainage, overland flow, extraction of water by plants and evapotranspiration, there may be very limited surface water. The hydraulic architecture that plants use to adapt to karst topography is very interesting, bu...

SWAT is a GIS-based basin-scale model widely used for the characterization of hydrology and water quality of large, complex watersheds; however, SWAT has not been fully tested in watersheds with karst geomorphology and downstream reservoir-like embayment. In this study, SWAT was applied to test its ability to predict monthly streamflow dynamics for a 1,555 ha karst watershed, Chapel Branch Cree...

Karst aquifers are a particular type of groundwater system that supplies drinking water in Puerto Rico, as well as in several U.S. regions and around the world. The karst aquifers contain cave systems that are vulnerable to contamination from toxic chemicals, such as TCE. This is because these contaminants tend to be trapped in the rock formations as nonaqueous phase liquids (known as NAPLs) an...

The classification method of karst formations is widely used in engineering and environmental geology but seldom petroleum geology. In this study, the applied to sealing study shale gas roof floor carbonate rocks, influence on accumulation drilling discussed. Paleozoic black southern China primarily formed by marine transitional faces, intergrowth between rocks a basic geological feature strata...

The possibilities of the raster-GlS topoclimatic modelling and its applicability in the Karst bioclimatology have been generally presented. The short descriptions of the particular models derived from the digital elevation model include: terrain slope, relative terrain orientation, terrain curvature, direct and diffuse insolation, altitude in the sinkhole, flow accumulation and exposure to wind...

Abstract Plants growing on karst soils, which are characterized by high pH (>7.5–8.0) and low phosphorus availability, often exhibit deficiency. However, little is known about the soil nutrient availabilities foliar concentrations of trees in ecosystems with lower (<7.0). In this study, we analyzed properties leaf litter from two secondary forests Asian monsoon temperate region Japan, one...
