Transmissivity Resolution Obtained from the Inversion of Transient and Pseudo-Steady Drawdown Measurements

Abstract

A key aspect of estimating transmissivity distributions from pumping tests is the spatial resolution of the estimation. Some assumption of spatial structure is needed to make an inversion possible. Both the nature of groundwater flow and assumed structure cause a smeared estimate. This research is focused on the how information content of the data smears the estimate. The inversion procedure near the solution is approximated as iterative linear updates. Linear resolution analysis of the distributed sensitivity to transmissivity indicates the limit of detail possible from the inversion.
