It is necessary to take water from the specific layer of the water source when supplying water from the industrial enterprises including atomic and thermal power stations. With such selective water intake from the stratified reservoir it is necessary to prevent the flowing in of water from other layers into the water-intake window. The purpose of the work is a development of automation for the theoretical design of selective water-intake devices and obtaining the calculation formulas, which include all parameters of water-intake process.

Hydrodynamic theory of surface and internal gravity waves in ideal incompressible liquid is the foundarion of this study. Contact initial-boundary value problem is solved analytically using the methods of operational calculus and integral Fourier transforms in the space coordinates.

Calculation formulas are obtained, which make it possible to automate all the computational procedures, and to calculate overall dimensions and marks of the waterintake window deep layout and expenditure or the rate of water withdrawal through the window in order to ensure the selective water-intake strictly from the specific layer. The results of the computational experiments, which use these formulas have showed the advantage of the authors approach compared to the empirical formulas mentioned above.

We propose the design of selective water-intake devices that use the obtained calculation formulas, derived on the basis of a strict hydrodynamic theory of surface and internal gravity waves instead of the design based on the currently used empirical estimations.
