Abstract
The properties of a Pleistocene aquifer located in NW Germany were evaluated by means of an inverse two-dimensional numerical model in the vertical plane. The steady-state drawdown recorded at the end of a pumping test was used to calibrate the model with a Gauss-Newton parameter estimation method. The results were analyzed within a formal statistical procedure by means of eigenvalues and eigenvectors. Although a mathematically meaningful value for the standard error can be obtained, the resulting set of permeabilities depends strongly upon the choice of the zonation pattern.
