Karst landscape overview THE 52,830 ACRES OF MAMMOTH CAVE NATIONAL PARK are part of the South-Central Kentucky Karst, which is characterized by subterranean drainage to springs on major rivers. From the southeast to the northwest portion of the landscape (Figure 1), there is a gradient of decreasing maturity in karst development, which corresponds to the regional dip of the bedrock. The major c...

Abstract The Semmering Base Tunnel (SBT), with a total length of 27.3 km, is one the leading construction projects Baltic-Adriatic Railway Network. tunnel connects two federal provinces Lower Austria and Styria cuts through eastern part Alps. lot SBT 1.1-Tunnel Gloggnitz characterized by complex geological- hydro-geological architecture containing alternating competent geological structures, ma...

The Indonesian province of East Kalimantan is home to some of the largest remaining contiguous tracts of lowland Dipterocarp forest on the island of Borneo. Nest surveys recently conducted in these forests indicated the presence of a substantial population of Eastern Bornean orangutans (Pongo pygmaeus morio) in the Berau and East Kutai regencies in the northern half of the province. The Sangkul...

Karst ecosystems are important landscape types that cover about 12% of the world's land area. The role of karst ecosystems in the global carbon cycle remains unclear, due to the lack of an appropriate method for determining the thickness of the solum, a representative sampling of the soil and data of organic carbon stocks at the ecosystem level. The karst region in southwestern China is the lar...

The purpose of this article is to present a model of the formation processes of cockpit karst landscapes. The CHILD software was used to simulate landscape evolution including dissolution processes of carbonate rocks. After examining briefly how the CHILD model operates, two applications of this model involving dissolution of carbonate rocks are presented. The simulated landscapes are compared ...

Karst reservoir has great hydrocarbon potential, however karst prediction is inhibited by the strong lateral and vertical heterogeneity of karstification which in turn results recognition difficulty when geological geophysical methods are used isolation. Combined methods, including core observation, thin section analysis, well log interpretation, seismic attributes inversion applied to understa...

Understanding the complex structure of karst networks is a challenge. In this work, we characterize the fractal properties of some of the largest coastal karst network systems in the world. They are located near the town of Tulum (Quintana Roo, Mexico). Their fractal dimension df , conductivity exponent μ̃ and walk dimension dw are estimated using real space renormalization and numerical simulat...

In fluviokarst landscapes flow may be partitioned into its surface and subsurface components as well as into diffuse and concentrated flow. The competition among these is hypothesized to be responsible for the divergence of the landscape in a fluviokarst region of central Kentucky into depression-rich, unchannelled karst-rich and channel-poor (KRCP) and strongly fluvially dissected channel-rich...

The Interferometric Point Target Analysis (IPTA) technique and Advanced Synthetic Aperture Radar (ASAR) images acquired over Hong Kong from 2007-2008 were used to detect ground deformation in the urban area of Guangzhou city in South China. A ground deformation rate map with scattered distribution of point targets shows the maximum subsidence (rise) rate as high as -26 to -20 mma(-1) (16-21 mma...
