TL;DR: The paper identifies instruments, provides examples of their use, and describes how synergy between measurement and modelling could be achieved, and provides a vision for the use of electrical and magnetic geophysical instrumentation in watershed scale hydrology.

TL;DR: In this paper, a sequential injection/withdrawal experiment was designed for monitoring the pump-and-capture remediation of a conductive solute in an unconfined alluvial aquifer.

TL;DR: In this article, a multivariate statistical technique, known as k-means cluster analysis, is used to correlate and integrate information contained in velocity and attenuation tomograms, and a comparison of the clustered tomographic section with well-log data demonstrates that their approach delineates the hydrostratigraphic zonation.

TL;DR: In this paper, a field-scale assessment of hydraulic tomography in a porous aquifer, with an emphasis on the steady shape analysis methodology, is presented, and the hydraulic conductivity (K) estimates from steady shape and transient analyses of the tomographic data compare well with those from a tracer test and direct-push permeameter tests, providing a field validation of the method.

TL;DR: In this article, a scattering-type equation is proposed to describe the sensitivity of electrical potential to both source and receiver positions, which is described by a scattering type equation and depends not only on source-receiver separation, but also on the location and magnitude of contrasts in electrical conductivity.
