In 1993, a large radio telescope (LT, now referred as the SKA) was proposed by astronomers from 10 countries at the 24 General Assembly of URSI. The SKA would be a telescope array with a total effective collecting area of about one square kilometer. There are various concepts, worldwide, for realizing the SKA project. Extensive efforts have been made, e.g, by project teams in The Netherlands, A...

The existence of karst cavities has an important impact on the safety foundation pit excavation projects. It is engineering guiding value to study influence blasting process pits and how optimize stiffness cement mortar improve effect. Based bench project Shenzhen Dayun Foundation Pit Project, this paper adopts SPH-FEM coupling calculation method cavities, cavity-filling water silt clay rock-bl...

A review of case histories of reservoir-induced seismicity (RIS) in China shows that it mainly occurs in granitic and karst terranes. Seismicity in granitic terranes is mainly associated with pore pressure diffusion whereas in karst terranes the chemical effect of water appears to play a major role in triggering RIS. In view of the characteristic features of RIS in China, we can expect moderate...

An isolated limestone hill (Cisowa Skała), located in the Podhale Basin southern Poland, has yielded mollusc shells and small vertebrate bones deposits filling karst forms such as rock shelters, characteristic molluscan assemblages can be identified, succession of which reflects changes environment also microhabitat variations depending on local factors, slope exposure type vegetation. These fa...

This paper deals with a landscape evolution model to compute cockpit karsts landforms. The CHILD model is used to model geomorphic processes at regional scale. After examining briefly CHILD’s principles and equations of limestone dissolution processes, the denudation model is detailed. The relation between subcutaneous dissolution and denudation of the topography is introduced by means of an em...

Water resources from alpine and other mountainous karst aquifers play an important role for water supply in many European countries. As regulated in the WFD (Water Framework Directive), karstic catchments require sustainable protection. The increasing strains to such regions and the different utilization in the watersheds of karst springs are important triggers to establish early warning system...

The upper carbonate member of the Kaibab Formation in northern Arizona (USA) was subaerially exposed during the end Permian and contains fractured and zoned chert rubble lag deposits typical of karst topography. The karst chert rubble has secondary (authigenic) silica precipitates suitable for estimating continental weathering temperatures during the end Permian karst event. New oxygen and hydr...
