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...

Abstract In recent decades, World Heritage Sites (WHSs) have faced external severe threats in the context of global economisation and urbanisation. The buffer zone as a conservation layer management tool for WHSs has attracted increasing scholarly attention debate. However, there is limited understanding zones’ social ecological role Natural (WNHSs) lack summary research progress on zones. To f...

abstract one of the importance groundwater resources in kermanshah province is karstic aquifer. this study aimed to investigate the role of development of karstic aquifer in karst springs hydrological properties have been conducted. the studies areas are two karst aquifers include the bistoon-parau and patagh mountain in kermanshah province. in the bistoon-parau region we used of bistoon, berke...

LADS (Laser Airborne Depth Sounding) is a new laser bathymetric survey tool that has applicability in clear coastal (Case II) waters down to -70 m depth. The new sounding technique features rapid acquisition of large high-quality data sets via variable swath widths that are independent of water depth. This advanced airborne laser bathymetric (ALB) system was deployed along the southeast Florida...

Koločep bay is a 30 km elongated karst basin located between the Elafiti Islands and mainland with NW–SE general direction. The lies within seismically active southern Dalmatia zone. Irregular grid sub-bottom profiles two legacy reflection seismic have been used to determine overall morphology of establish stratigraphy its sedimentary infill. Three major seismic–stratigraphic units identified i...

One of the current objectives of karst research is to understand the spatial dynamics of karstic processes that increase or decrease pore volume. Although we can construct 3D numerical models, it is a complex, multi-step process. These modelling approaches combine a dissolution algorithm, a flow and/or transport model and an algorithm to reconstruct the spatial geometry of fracture networks. Th...

The Jinan spring basin is located in the karst area of northern China, where springs serve as important sources water supply. Several studies on protection and supply have been carried out, scholars developed some laws local groundwater flow dynamic characteristics aquifer structures. Unfortunately, there a lack detailed research preferential recharge zones, which are main pathways springs. The...

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...
