Hydraulic calculation of horizontal open drainages

Abstract

In article analysed the factors influencing the hydraulic processes which arise in the open horizontal drainage systems. Open drainages plays important role in order to improve the ameliorative condition of the agricultural area, salt washing on the soil. It is emphasized that the deep drainage in our region has a good effect on the soil condition and salt removing. At present, efforts are being made to improve the productivity of the collectors to clean and built. As example the collector drainage systems in Syrdarya region are listed. It is observed that the motion mode of open drainage flows is physically identical. Due to the complexity of equations in the unstable motion mode, the drainage water flow scheme in the collectors reflects the hydraulic calculation of the movement. Researches were provided in open agricultural drainage system of Syrdarya region and analysis have been done in natural field conditions. It has been noted when slope of the drainage bed is equal to i<0,0005 intensity of deformation were very high, when slope was between 0,0005
