Evaluation of the hydraulic efficiency of the sprinkler irrigation system

Abstract

Abstract The article describes the methods of conducting some field studies to evaluate the effectiveness of sprinkler irrigation systems and to design them reliably. Also, the distribution of discharge in the irrigation system across the territory and its losses are analysed. Christiansen’s coefficient of similarity “CU” is used to estimate sprinkler water distribution. It is carried out by studying three types of combinations according to the Catch Can method: sprinkler height, sprinkler discharge and pressure changes. In order to determine the Christiansen coefficient, it is calculated using the sum of experiments in taking into account the distribution of discharge according to the height of the sprinkler at several different pressures. Based on the method given above, the optimal height was determined in the assessment of water distribution. Based on field experiments and their analysis, a graph was created based on sprinkler height and flow distribution for discharge.
