Complementary use of tracer and pumping tests to characterize a heterogeneous channelized aquifer system in New Zealand
The combined use of pumping and tracer test data enabled the derivation of equivalent average hydraulic conductivities (K avg) for each test in a heterogeneous channelized alluvial aquifer, whereas K values of the preferential flow paths were two orders of magnitude higher. Greater and earlier drawdown was generally observed along preferential flow lines in a pumping test, within an array of 21 wells. The study aim was to characterize hydraulic properties of a channelized aquifer system in New...[Show more]
