The general methodic of forecasting the flow and moisture-salt transfer processes in saturated-unsaturated media on the base of the methods of mathematic modeling for case of the arbitrary vertical domains is proposed.The practical example of the solution the migration problem of pollutions at filtration from the irrigated channel to reservoir is demonstrated.

The methodic of evaluation of the innerdrain hydraulic of the water flow along the length of the drains of the ranney drainage (water uptake) on summary inflow to them is developed. The methodic is based on the mathematical models which allow more fully to take into account the complex real flow character and the hydraulic conditions in the zone of the influence ranney water intakes and drainages. The different cases of solution of joint problem of flow in aquifer and in the drains-rays are considered and presented as the system of the analytic dependences. Obtained results showed that the inflow to drain-ray is distributed uneven along its length and the main inflow is formed in the first half of the drain-ray. Therefore, in some cases the influence of innerdrain hydraulic should be taken into account when calculating the parameters of drainage and evaluation of their operation.
