The mathematical formulation of problems of flow in aquifers is usually based on a formulation of the fluid mass balance, which has to be fulfilled at any location in the domain under consideration. A knowledge of the fluid mass flux through the saturated aquifer material, or the motion equation, is required. The resulting partial differential equation can be solved for a chosen flow domain, given parameters, and initial and boundary conditions. The solution results in the steady state or transient field of the piezometric head, from which the flux and the velocity fields may be expressed.
