flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Karst voids were encountered during road construction in Yongweol-ri, South Korea Attempts to determine the extent of the karst voids through drilling was expensive, time-consuming and too dangerous An electrical resistivity survey was thus carried out to investigate current subsurface geology beneath the proposed road network This investigation was aimed at imaging karstic voids and detecting ...

The archaeological karstic infill site of Galería Complex, located within the Atapuerca system (Spain), has produced a large faunal and archaeological record (Homo sp. aff. heidelbergensis fossils and Mode II lithic artefacts) belonging to the Middle Pleistocene. Extended-range luminescence dating techniques, namely post-infrared infrared stimulated luminescence (pIR-IR) dating of K-feldspars a...

Abstract. Excessive sediment discharge in karstic regions can be highly disruptive to water treatment plants. It is essential for catchment stakeholders and drinking suppliers limit the impact of high loads on potable supply, but their strategic choices must based simulations integrating surface groundwater transfers taking into account possible changes land use. Karstic environments are partic...

Significant evolutionary stages of Selinitsa Cave (SW Peloponnese, Greece) were revealed by 3D mapping, as well geomorphological study the cave and nearby landscape. Four marine terraces identified in area coastal at 6, 10.7, 16.6, 30–32 m above sea level (asl), with terrace 16.6 representing Marine Isotope Stage (MIS) 5. The widest karstified space clusters between 15.73 18.05 peak lying 16.4 ...

Due to the limited distribution of karst rocks and, accordingly, small number caves in Ukrainian Carpathians, non-karst (pseudokarst, clastokarst) genesis attract considerable attention from cave researchers. The latter most often develop massive and coarse-grained sandstone strata, usually found as part flysch strata. non-karstic are widely spread Cretaceous Paleogene formations Carpathians. M...
