Dynamics of processes of moisture redistribution in water balance of agrolandscapes was studied with the use of analytical modeling. Water balance is represented as the result of changes in its components with time. Atmospheric precipitation and its interception on the surface by plants, water accumulation in depressions on the slope, infiltration, and slope runoff are simulated in combination with the processes of vertical water flow to groundwater in the context of system dynamics. Analytical modeling is used as a basis for the representation of the system dynamics in the mode of a simulation modeling of hydrological processes of soil moisture accumulation. Modeling of vertical water flow is based on the semiempirical description of moisture conductivity and retention in the aeration zone.
