Aquifer heterogeneity characterization with oscillatory pumping: Sensitivity analysis and imaging potential

M Cardiff, T Bakhos… - Water Resources …, 2013 - scholarworks.boisestate.edu
Periodic pumping tests, in which a fluid is extracted during half a period, then reinjected,
have been used historically to estimate effective aquifer properties. In this work, we suggest …

Three‐dimensional transient hydraulic tomography in a highly heterogeneous glaciofluvial aquifer‐aquitard system

SJ Berg, WA Illman - Water Resources Research, 2011 - Wiley Online Library
Hydraulic tomography has been proposed as an alternative site characterization method,
however, relatively few field scale studies have been attempted. In this paper, we …
