First the groundwater movement equations and continuum equations are derived, and accordingly the differential equations of groundwater steady seepage are derived.

A boundary fitted coordinate Finite Analytical Method (FAM) is described for the numerical solution of steady and unsteady seepage flow with pressure in foundation of sluice and DAMS.

For example, a pond in hilly country that maintains a steady water level all through a dry summer in spite of having no streams flowing into it must obviously be seepage dominated.
