Improvement of the Calculation of the Closed Collector-Drainage Network of Drainage Systems

Abstract

The necessity and scientific and methodological approaches to improving the calculation of a closed collector-drainage network of drainage systems are considered. Based on the application of the system methodology, the structure of the hierarchical and hydraulic connection between the water regime of the field and the operation mode of the closed collector-drainage network has been established. On the basis of the theoretical and experimental studies performed, relatively new scientific provisions have been proposed. This will allow, based on the application of the obtained universal equations, to construct a distribution profile of the total turbulent kinematic viscosity and the average flow velocity in the collector pipe. It becomes possible to evaluate the efficiency of the flow movement both in the constituent elements (collector pipes) and in the closed collector-drainage network as a whole. And it also becomes possible to improve the methods of designing and calculating their technological and design parameters.
