Evaluation of the matrix exponential for use in ground-water-flow and solute-transport simulations; theoretical framework
A.M. Umari, S.M. Gorelick
1986, Water-Resources Investigations Report 86-4096
It is possible to obtain analytic solutions to the groundwater flow and solute transport equations if space variables are discretized but time is left continuous. From these solutions, hydraulic head and concentration fields for any future time can be obtained without ' marching ' through intermediate time steps. This analytical...
