Estimation of Transmissivity and Permeability in Swedish Bedrock
Estimation Transmissivity Permeability Swedish Bedrock
2009/10/29
Statistical analysis of pumping-test data from wells have been used to calculate
average values of transmissivity and permeability in different Swedish rocks. The
influence of the well-loss on the c...
MODELING OF CHEMICAL AND ELECTRICAL FLOWS IN LOW PERMEABILITY SOILS UNDER ELECTRICAL GRADIENT
ELECTRICAL FLOWS LOW PERMEABILITY SOILS CHEMICAL ELECTRICAL GRADIENT
2009/10/19
If an electrical gradient is imposed on wet fine-grained soil, contaminant transport occurs by a complex phenomenon called electrokinetics. Even though electrokinetics has been proven to be feasible i...
AN ALTERNATIVE METHOD TO EVALUATE AQUIFER PERMEABILITY
AQUIFER PERMEABILITY geophysical logs porosity aquifers
2009/10/13
New techniques are described to evaluate complex dual porosity aquifers using geophysical logs. Alternatives are presented to characterize highly heterogeneous rocks and identify the presence of prima...
Assessing winter storm flow generation by means of permeability of the lithology and dominating runoff production processes
winter storm flow coefficients permeability of the lithology runoff production processes
2009/5/13
In this study two approaches are used to predict winter storm flow coefficients in meso-scale basins (10 km² to 1000 km²) with a view to regionalization. The winter storm flow coefficient co...
