SPRINKLER IRRIGATION SYSTEM MANAGEMENT BASED ON ENGINEERING DESIGN FACTORS

Abstract

The high efficient sprinkler irrigation system had become more desirable since 1950s instead of traditional irrigation system to improve the water application. The sprinkler irrigation uniformity is affected by many engineering design factors such as nozzle characteristic, operating pressure and raiser height. A. The aim of this study: To minimize losses of sprinkler irrigation system by increasing sprinkler irrigation system besides decreasing the cost without missing the hydraulic design properties of the system. So the objectives were: • Improving sprinkler irrigation system performance by studying the effect of nozzle characteristics, changing velocityand overlapping on sprinkler performance. • Increasing sprinklers performance at different raiser heights and overlapping ratio to decrease the total annual cost and apply water efficiently. B. The Methodology of the Experiments: 1. Laboratory Experiments: between 2017-2019 in The National Laboratory for Testing the Components of Irrigation Networks and Field Drainage, Agricultural Engineering Research Institute AEnRI, ARC. • Test the performance of the sprinkler under different nozzles characteristics and roughness connectors (P) at different operating pressure. • Design nozzle No 7 (low pressure) and roughness connector.
