Reviewed by hydrological and hydraulic processes on reclaimed territories and quantification of their manifestations, methods of artificial modification of hydraulic regime of irrigation. Mathematical description of the regularities of the characteristics of the flow of water in the artificial stream (furrows), interaction of water flows with side slopes and bottom grooves. Hydraulics of irrigation considered with the use of water and heat balance on the basis of monitoring of water Wednesday in furrows, since irrigation furrow irrigation water needs perfectly due to large evaporation losses and uneven absorption of soil. Describes how to mathematical calculations, irrigation norm that must be strictly followed to conserve water for irrigation by furrows. Application of polyethylene film perforated screen will provide the necessary moisture throughout the season. Offered the most effective modalities and agrotechnical recommendations.
