| Abstract | Borehole flowmeter measurements obtained during pumping can be effective in determining profiles of hydraulic conductivity (K). Few tests have been reported on flowmeter in full-screened wells that
penetrate unconsolidated aquifers. In this paper, we demonstrate the utility of the flowmeter technique in quantifying the spatial variability of K and in distinguishing hydrofacies in an unconsolidated heterogeneous aquifer that exhibits low to
moderate K. Results indicate that: (1) comparison of K values obtained from flowmeter measurements and multilevel slug tests shows differences consistently below 10%, and (2) individual hydrofacies can be delineated based upon K contrasts. |
