The parameters used to describe the electrical conductivity of a porous material can be used to describe also its thermal conductivity. A new relationship is developed to connect the thermal conductiv...
Chemical changes in water circulating deep in the fissures of the solid
rock are studied. The ultimate chemical composition is determined by
the conditions of percolation through the soil zone. For ...

Hydrogeology of Crystalline Rocks:Case Studies of Two Areas in India
Hydrogeology Crystalline Rocks Case Studies Two Areas India
2009/10/28
Two-thirds of India is underlain by consolidated rocks and approximately onehalf
of this hard rock area is composed of Precambrian crystalline rocks. Many
rural areas in India are dependent on groun...
Estimation of Aquifer Parameters by Least-Squares Method under Linear Flow Conditions in Fractured Rocks
Aquifer Parameters Least-Squares Method Linear Flow Conditions
2009/10/26
Pumping and recovery test data in phyllite formations were analysed under linear
flow conditions by incorporating modification in the method proposed by Sen
(1986). Although the Sen (1986) method is...

A series of boreholes of up to 50 m depth, drilled into Lower Palaeozoic mudstone, shale and greywacke bedrock in the headwater catchment areas of the River Severn at Plynlimon in Central Wales, show...
Infiltrative instability near topography with implication for the drainage of soluble rocks
Infiltrative instability soluble rocks topography
2009/5/6
We present here numerical modeling of infiltration instability near a topographic edge of a water-saturated porous slice by analogy with a limestone formation devoid of initial heterogeneities such as...
