EFFECTIVENESS OF RECONSTRUCTION OF DRAINAGE SYSTEMS IN POLESIE WITH SELECTIVE ARRANGEMENT OF THE REGULATORY NETWORK BY THE SQUARE

Abstract

It is proved the necessity to develop new design solutions for the reconstruction of drainage systems in relation to changing environmental conditions of Polesie. We propose new principles of their actions. There are economic indicators of one of the most promising drainage systems with selective drainage compared to an open network and systematic drainage. It is shown the efficiency of the control of soil water regime of this system, and increased by 2.3 times the land productivity as a result of its use in the reconstruction of objects. Based on research it is proposed the schemes of reconstruction of drainage systems, designed to ensure the conditions of intensive agricultural production on lands under different natural conditions, including extreme.
