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...

The Zagros Fold and Thrust belt is one of the world's most prolific petroleum provinces. Most hydrocarbon reserves are stored in naturally fractured reservoirs such fracture systems can therefore have a significant impact on reservoir performance. Fractures important paths for fluid flow carbonate reservoirs. Fracture data were collected outcrops Kirkuk Group Oligocene age around Qara Chauq Sou...

From the 1970s, Dead Sea experienced severe halo-karstification and anthropogenic modifications. Progressively, but at an accelerating rate, subsidence, landslides, sinkholes have increased in number magnitude. The hazards’ triggering factors are terminal lake level lowering more than one meter per year dynamic equilibrium of hydrogeological system. Over Lisan peninsula, archived satellite imag...

In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...
