CALCULATION OF A HYDRODYNAMIC MODEL FOR CONTROLLING THE MOISTURE TRANSFER REGIME

The most important task of hydrodynamic forecasts in connection with land reclamation is to predict changes in the groundwater regime and control the moisture transfer regime in the upper layers of the aeration zone. In this regard, for the development of hydraulic models of moisture transfer, it is necessary to take into account the physico-mechanical properties of soil, hydrophysical characteristics of soil type, conditions for moisture entry into soil [1,2]. It is known that the soil is a dispersed body, i.e. it consists of a large number of particles of different sizes, mostly small and very small. The consequence of this is the well-known fact that the soil is a porous body, i.e. permeated in all directions by a large number of interconnected gaps between particles. It is in these gaps-pores that the moisture that enters the soil or into the ground accumulates [3,4]. The article describes comprehensively study of the processes of forecasting changes in the groundwater regime and control of the moisture transfer regime in the upper layers of the aeration zone.
