Modeling transport in transient ground-water flow: An unacknowledged approximation
Daniel J. Goode
1992, Ground Water (30) 257-261
During unsteady or transient ground-water flow, the fluid mass per unit volume of aquifer changes as the potentiometric head changes, and solute transport is affected by this change in fluid storage. Three widely applied numerical models of two-dimensional transport partially account for the effects of transient flow by removing terms...
