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...

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...

Since artificial neural networks (ANNs) can approximate any function, they have been applied in many fields including hydrology. In hydrology, there are important issues such as flood estimation and predicting rainfall-runoff in a certain area. In this presentation, we briefly introduce a popular feed-forward neural network model, so called “multi-layer perceptron (MLP)”, and review its applica...

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...

Karst terrain confounds efforts to parameterize and calibrate The Soil Water Assessment Tool (SWAT). purpose of this study was use SWAT simulate long-term natural (e.g. climate) human land use) impacts streamflow, sediment nutrient loading in a karst catchment. Sub-objectives were to: (1) perform rigorous model performance assessment SWAT, (2) apply highlight critical source areas NPS pollutant...

lysogeny, transduction, radiation effects, genetic expression, and comparative aspects. Stent's real purpose in writing the book is probably revealed in a statement at the end of the seventh chapter in which he states that it has fallen to the students of the bacteriophage to bridge the gap between chemistry and genetics-hence the term "molecular genetics" and, no doubt, the title of his text. ...

Abstract In the region of karst, there are valley areas that used by community as agricultural land. However, drought phenomena often occur in this area, so it is necessary to know presence water support processes. The aim research predict flow rates several systems using Soil and Water Assessment Tools (SWAT). SWAT was chosen because can simulate model with easy-to-obtain data. Required data s...

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...

Integration of GIS and hydrologic models has been a common approach for monitoring our ever-changing hydrologic system. One important issue in adapting such an approach is to ensure the right correspondence of data across databases. To reach this goal, it is necessary to develop a description of the surface hydrology concepts that is internally consistent and semantically rich. In this paper, w...
