Since rockfill has high permeability the size of rockfill intake is limited and construction costs is very low compare to other methods. Regarding that in coarse media the reynolds number exceeds it’s critical value, there for analyzing this kind of flow the well-known Laplas equation can not be used. In this paper it is shown that by using one of the suggested equation between pizometric (i)and drift valocity in porous media (i=mvn) and it’s combination whit continuity equation, a differential equation could be derived that the height of pizometric and potential function Φ results from it’s direction of velocity vectors ultimately the capasity of rockfill intake could be calculated. The solution of a bove differential equation is explained by finit difference method.
