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...

A new subgenus and new species of anophthalmic trechine beetles, Oodinotrechus (Pingleotrechus) yinae subgen. n., sp. n., is described and illustrated from a limestone cave called Chaotianyan in southern part of Guilin karst, northeastern Guangxi Zhuang Autonomous Region. The new taxon is very different from the Maolan-Mulun congeners belonging to the nominate subgenus Oodinotrechus (s. str.) U...

introduction the iran has vast areas of karst landforms due to the relatively high carbonaceous rocks deposited during different geologic eras. karst landforms are noteworthy for investigation from many aspects. the primary importance of these regions is the considerable amount of underground water stored in karst formations. these reserves are favorable, both in quality and quantity, as natura...

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...
