similar fractured rock formations elsewhere. One possible means for obtaining such estimates is the use of The search for a permanent storage facility for the geological distension infiltrometers. posal of high-level nuclear waste has motivated extensive research Tension infiltrometers have long been used in soil hyduring the past several decades to characterize and predict fluid flow into and ...

The development of hydrogeology with respect to hard-rock and fractured-rock aquifers is described. differences between porous karst are explained, as well the groundwater flow regimes in different fractured rocks. A position taken on numerical modeling, from beginning modeling present day, focus particular challenges. Because importance aquifers, tools for exploration future resource managemen...

the deformation modulus of a rock mass is an important input parameter in any analysis of rock mass behavior for geotechnical projects such as dams. the determination of this parameter by in situ tests are time consuming and expensive. therefore, different researchers have proposed empirical relationships for estimating the value of rock mass deformation modulus. this work has been done by usin...

Characterisation of the heterogeneous naturally fractured reservoirs is an essential and significantly challenging task, especially due to the limited data availability. This paper presents a foundation relationship between P-wave / S-wave velocity and formation resistivity for improved fracture characterisation. Rock matrix and fluid volumetrics are combined with the basic correspondence betwe...

In this study we determine constitutive relations (relations between saturation, hydraulic conductivity and pressure head) for unsaturated fractured rocks using a computational procedure that mimics the laboratory technique of measurement. Isotropic three-dimensional rock samples with random vertical and horizontal fractures are computationally constructed. Each fracture is conceptualized as a ...
