Purpose: research and development of design solutions for drainage and watering systems using linear and frontal-circular movement sprinkling machines for the effective use of system water resources when draining and moistening reclaimed lands in non-sloping (low-slope) areas and with a slight slope.
Materials and methods. During the research, the well-known design solutions of drainage and watering, irrigation and water circulation systems of various scientists were analyzed. In the course of analysis of constructive solutions and methods of movement, analytical, comparative and logical methods were used. When developing (improving) design solutions, the design method was used.
Results. During the research, it was found that in the humid zone, due to the decrease in irrigation norms, there is a possibility of increasing the seasonal load of sprinklers. Based on the results of studies of the principles of moving sprinkler machines and currently used design solutions in order to reduce energy consumption and increase the land use coefficient, three design solutions have been proposed for reclaimed lands with different slopes. It is proposed to use frontal and frontal-circular sprinklers in drainage and watering systems. Humidification in these solutions is carried out by accumulated drainage runoff with the possibility of discharging its excess water into a water intake-water source, as well as, additional withdrawal from it in case of necessity.
Conclusions. As a result of the research, the constructive solutions for drainage and watering systems have been proposed using frontal-circular and frontal sprinklers on non-slope (low-slope) reclaimed lands, as well as those with a slope, which make it possible to reduce the number of sprinklers due to reduced irrigation norms and the location of the combined drainage-watering and watering networks.
