Abstract
The purpose of this study is to develop a numerical model to simulate the behavior of the head potential fluctuation in subsurface flow. Numerical and analytical solutions are presented. Impacts of the storativity and porosity on the head potential fluctuation are investigated in this paper. It is found, in one-dimensional subsurface flow, that the less the storativity, the easier the fluctuation of the head potential propagates. In addition, an asymptotic behavior of the head fluctuation does not reach until the head propagation travels more than 0.75 times the total aquifer length.
