REVIEW OF DRAINAGE-IRRIGATION SYSTEMS WITH MAXIMUM RENEWABLE NATURAL RESOURCES USE

Abstract

Purpose: review of drainage-irrigation systems with the maximum renewable natural resources use. Materials and methods. In the process of conducting a scientific review of double-acting irrigation systems with the maximum use of renewable natural resources, the analytical, logical, systemic and comparative methods of scientific research were used. The scientific research base was presented by the existing design solutions of complex irrigation systems aimed at the maximum use of renewable natural resources at the level of patents, as well as scientific literature. Results. As a result of the review, it was revealed that drainage irrigation systems consist of drainage and moisturizing parts. The following humidification methods are distinguished in these systems: surface moistening, subsoil, intrasoil (which can also include drip irrigation) and sprinkling. The drainage-irrigation systems using renewable natural resources include systems with accumulating drainage runoff with a closed water rotation, full or semi-water rotation. By the method of accumulating drainage runoff, they are divided into systems: with vertical drainage, with an underground reservoir, with collectors and storage drains, with storage wells, temporary accumulation sections with their various combinations. Conclusions. Various storage drains are included in the structure of the above systems. When developing new structures, it is necessary to take into account all the shortcomings of existing structural solutions (provide for a sufficient volume of storage ponds, measures for cleaning from harmful impurities, measures to reduce evaporation and filtration for reducing the size of storage tanks), which will allow the comprehensive use of natural resources due to accumulation and redistribution drainage runoff inside the double-acting system.
