When steady state flow occurs, time is no longer an independent variable and thus the storage term in the groundwater flow equation disappears; since there is no change in the amount of water within the domain (no change in hydraulic head) there is obviously no …

Equation - Conservation of Mass Unsteady groundwater flow to a pumping well in a confined aquifer is described by the equation (Bear, 1979, p. 320): The equation describes mass conservation of groundwater flow in the radial direction allowing for change in storage volume (expansion or contraction of the confined water due to change in pressure).

The convergence of the method of successive approximations in the solution of non-Darcian seepage flow is rather slow. In this case we should expect to have to carry out 5 to 8 approximations. Another possibility in the solution of non-linear problems of steady groundwater flow is the application of the Newton-Raphson method.

The steady-state flow of groundwater is described by a form of the Laplace equation, which is a form of potential flow and has analogs in numerous fields. The groundwater flow equation is often derived for a small representative elemental volume (REV), where the properties of the medium are assumed to be effectively constant.
