Abstract
Since the primary transport mechanism in a subsurface flow is advection, accurate determination of the velocity of the carrier fluid percolating through the porous medium is extremely important. Computer-based groundwater motion simulators conventionally use pressure as the primary variable, and after the pressure field has been calculated, the velocity is determined by numerical differentiation. It will be shown that this is an unreliable procedure and, for that reason, an approach to direct determination of the velocity field will be presented.
