ABSTRACT

A technique for evaluating the amount of washout of soil from the plot of land at the time of prediction based on the constructed hydrodynamical model of the flat inclined turbulent rain flow is presented. In the description of the boundary conditions the equation of moisture transfer in a new statement is used in which the dependence of the gravity potential on the volumetric humidity is taken into account and also the velocity of movement of the border of the saturated zone is determined.
