ON FILTRATION OF WATER IN A SCREENED RECTANGULAR BARRIER IN THE PRESENCE OF EVAPORATION FROM THE FREE WATER SURFACE

Plane steady-state fi ltration of groundwater in a rectangular barrier with a partially impermeable vertical wall in a bed in the presence of evaporation from the free water surface is considered. To study water fl ow by PolubarinovaKochina′s method, a mixed multiparametric boundary-value problem of the theory of analytical functions has been formulated and solved. Based on the results of the solution of this problem, an algorithm of calculating fi ltration characteristics of water fl ow through the indicated barrier has been developed, and an analysis of the effect exerted by the physical parameters of the system on the hydrodynamic fl ow pattern has been made
