Wadi Darnah is about 586 km2 and lies in the northern portion of Al Jabil AL Akhdar. The drains into Mediterranean Sea. present study incorporates a morphometric analysis by using remote sensing GIS techniques. Digital Elevation Model (DEM) topographic sheets were processed ArcGIS software. revealed that drainage patterns stream network from basin are mainly dendritic type which indicates homog...

The complex Krupaja karst system, located in Serbia, which consists of a strong spring, thermal and borehole that captures sub-thermal waters, has been studied. A phenomenon gives rise to the occurrence waters three different temperatures within relatively short distance (about 200 m) led us assume these are formed same aquifer circulate through levels channels zonally distributed vertical prof...

The Plio-Quaternary Ait Chaib basin occupies the northwestern part of Skoura Syncline, which is northern Middle Atlas Folded Zone. This intracontinental was formed probably in Pliocene after Tortono-Messinian regression sea. deposits are bound by fluvial conglomerates and continental carbonates. They consist barrage travertines; travertine limestones oncholitic silts sands upstream downstream d...

The process of evaluating rock mass strength requires that major structural features such as joints influence are considered. In carbonate masses, however, the is largely dependent on intact and play a secondary role. Laboratory experiments porous have shown reduces with increasing porosity, which has direct effect strength. Rock porosity however not been well accounted for in characterization ...

Abstract Daily precipitation and groundwater level data, registered at 7 rain gauge stations 11 monitoring wells in the Salento coastal karst aquifer (Southern Italy) were subject to short time series analyses evaluate hydrodynamic response of aquifer. Results show that system has general great storage capacity, which suggests a poor degree karstification, dominance permeability structure not w...

Extensive field and site investigations were conducted to assess evaluate the situation in presently exploited quarries of cement raw materials Yemen. These have several geological complications represented mainly by high elevations, steep slopes, rugged topography, heterogeneity bed thickness, lithologic composition quality, presence igneous sills dykes, intensive fracturing jointing abundance...

Karstification and the global carbon cycle are closely related. Understanding features of dissolution variations in carbonate rocks variables influencing is crucial for producing reliable estimates karst sinks. The seasonal rates primary factors affecting Maocun watershed, Guilin, examined under external source water (Xiaolongbei), (Beidiping), mixed (Bianyan) conditions. In this work, characte...

Cueva Victoria has provided remains of more than 90 species of fossil vertebrates, including a hominin phalanx, and the only specimens of the African cercopithecid Theropithecus oswaldi in Europe. To constrain the age of the vertebrate remains we used paleomagnetism, vertebrate biostratigraphy and (230)Th/U dating. Normal polarity was identified in the non-fossiliferous lowest and highest strat...
