Abstract
This paper follows those published in the 7/1995 et 3/1996 issues of La Houille Blanche. An expression of the aquifer top ground water drainage speed is established for the case of recession flow non influenced by the rain. It is then demonstrated that the cartesian chart with logarithme coordinates, proposed for the drain separation calculus in steady flow, leads generally to a solution for the recession flow.
