Abstract
A034 Z-99 Characterization of fractured rock aquifers by surface geophysical methods Summary Comparison of MRS results with static water level measurements and hydraulic conductivity estimation in boreholes shows that MRS method could be an efficient tool for investigation of weathered part of crystalline aquifers with the effective porosity greater than 1%. It was shown using both numerical modeling and field measurements that the MRS method allows characterizing two- dimensional subsurface formations. Presented field example proves that a combination of the MRS with 2D electrical imaging tool improves geophysical results in complex heterogeneous gneissic formations of Southern India.
