On two limiting cases of flow below Joukowski’s cutoff wall

Two schemes of fluid flow under the rabbet of Zhukovsky is considered. Filtering is flat and steady, and the fluid flow satisfy Darcy's law. The movement occurs through an array of ground underlain by permeable or impermeable base pressure aquifer. To study these schemes mixed boundary value problem of the theory of analytic functions are formulated. It is solved by means of application of a method of P. J. Polubarinova-Kochina. The algorithms for calculating the saturated zone in case when taken into account the simultaneous effect on the course of the following factors: backwater from the impermeable base or underlying well-permeable aquifer, evaporation or infiltration at the free surface groundwater and the capillary of ground.
