Abstract

In this article the tasks of open drainage are shown in improving the ameliorative condition of the sown areas. The scientific recommendations of scientists in the design and construction of drainage are considered. The aspects affecting the hydraulic processes occurring in the channels of open drainage are analyzed. The hydraulic parameters of open drainage used in the Syrdarya region are analyzed. The results of studies to improve the performance of open drainage are revealed. The effect of flow capacity on drainage efficiency is estimated. The results of calculations of the throughput capacity of the drainage flow in two sections are studied and disclosed. The bandwidth increase by 62 percent is justified, while the flow rate increases by 25 percent. From a hydraulic point of view, methods are shown to increase flow capacity. Scientific recommendations on the justification of hydraulic parameters in the design of open drainage are given.
Key words: drainage, course, expense, speed, stream, deposits, permeability.
