EVALUATION ENGINEERING GEOLOGY PROPERTIES OF JAMISHAN DAM SITE WITH EMPHASIS ON ITS GROUTABILITY (2012)
The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. Therefore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid ...
This study examined the flood risk in Port Harcourt using rainfall data, soil texture and other factors.
IN-SITU AND LABORATORY INVESTIGATIONS OF STRESS-DEPENDENT PERMEABILITY FUNCTION AND SDSWCC FROM AN UNSATURATED SOIL SLOPE (2011)
Permeability function of an unsaturated soil, k(\), where \ is suction, is a vital hydrogeological property that governs seepage in various geotechnical problems. Owing to considerably long test duration, direct measurement of k(\) is often avoided if at all ...
RESERVOIR EVALUATION OF WELL A, FIELD Y, NORTH-EASTERN NIGER DELTA: A CASE OF A PROBLEMATIC SANDSTONE (2011)
<p>In this paper the reservoir characteristics of well A, in field Y were evaluated using data derived from both wire line logs and cores.</p>
TEMPORAL AND SPATIAL PORE WATER PRESSURE DISTRIBUTION SURROUNDING A VERTICAL LANDFILL LEACHATE RECIRCULATION WELL (2011)
This paper reports experiences of leachate addition in a buried vertical well surrounded by multiple piezometers (pressure transducers) over a 2-year period. Data on spatial distribution of pore water pressure in the surrounding waste in response to cumulative ...
X-RAY MICROTOMOGRAPHY CHARACTERIZATION OF POROSITY, PERMEABILITY AND REACTIVE SURFACE CHANGES DURING DISSOLUTION (2010)
Numerical programs for simulating flow and reactive transport in porous media are essential tools for predicting reservoir properties changes triggered by CO2 underground injection. At reservoir scale, meshed models in which equations are solved assuming that ...
EVOLUTION IN PERMEABILITY IN SILICEOUS ROCKS INDUCED BY MINERAL DISSOLUTION AND PRECIPITATION (2009)
<p>A conceptual model is presented to follow the evolution of permeability in siliceous rocks mediated by pressure solution comprising the serial processes of interfacial dissolution, diffusion, and free-face precipitation.</p>
<p>The effective stress law for the permeability of a limestone is studied experimentally by performing constant head permeability tests in a triaxial cell with different conditions of confining pressure and pore pressure pf.</p>
<p>Different Permeabilities in eogenetic and telogenetic karst. Comparison and analysis</p>
To assess the role of the fault thickness on its mechanical behavior, we first present the results of an experimental modeling of a thick fault core. Our laboratory setup consists in an annular simple shear apparatus in which we can apply very large shear ...
