The dipole-flow test with a tracer: A new single-borehole tracer test for aquifer characterization

Journal article Journal of Contaminant Hydrology · January 1, 2000 We propose a new aquifer characterization test, the dipole-flow test with a tracer (DFTT), and develop its interpretation methodology. Combining the dipole-flow test (DFT) and a tracer test, the DFTT is a single-borehole, forced-gradient tracer test. The D ... Full text Cite
