COUPLED 2-D GEOPHYSICS TO BETTER CHARACTERIZE SHALLOW SAND AND GRAVEL AQUIFERS
Miles of seismic reflection profiles were coupled with electrical resistivity profiles to optimize interpretations of aquifer character. Thus, at the same locations, seismic-reflection profiles indicated aquifer boundaries and internal sediment structures, while electrical resistivity profiles indicated textural and facies changes within the aquifer. When combined, these data were complementary to one another and consistent with local and regional interpretations of the geologic framework. Furthermore, the new insights contribute greatly to better understanding how the geologic framework controls groundwater recharge and contamination potential.
