Effect of soil capillarity on seepage from a channel with evaporation

The method of Polubarinova-Kochina is applied to solve the seepage problem for a channel with evaporation and capillary soil. The capillary spread of water and the seepage discharge from the channel are investigated as a function of the height of capillary rise and evaporation rate. Results of numerical experiments are presented. The limiting case of flow without evaporation, previously studied by Rizenkampf, is considered.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 59, pp. 40–43, 1986.
