Résumé

The plane steady filtering depressurised to the formation of imperfect gallery in the presence of evaporation from the free surface groundwater. To study the effect of evaporation is formulated and using the method of P.Y. Polubarinova-Kochina solved multiparametric mixed boundary value problem of analytic function theory. On the basis of the proposed model, an algorithm for calculating seepage flow characteristics and provides hydrodynamic analysis of the impact of all the dependencies of physical parameters of the circuit in flow rate ordinate galleries and exit points of the curve depression on an impermeable screen.
