Modeling and analysis of hydraulic networks in drip irrigation systems.
Hydraulic networks for irrigation systems provide an excellent way to prevent excessive water and energy loss during irrigation. Closed loop hydraulic networks, which are a modification of traditional open hydraulic networks for drip irrigation, offer an alternative way in the designing of these systems. However, much is not known on the performance of closed loop hydraulic networks in the designing of mainlines for drip irrigation systems. This study aimed at comparing the use of open and closed loop hydraulic networks in the designing of mainlines for a drip irrigation system to determine the best design using fundamentals of pressurized hydraulics. EPANET 2.2 software was used to simulate and analyze the hydraulic networks on hydraulic parameters like pressure and velocity. Furthermore, the weight of the networks was determined as a cost indicator for the networks once the simulations satisfied the required hydraulic conditions. Closed loop hydraulic networks proved to ensure high pressure and velocities in the systems when compared to open loop hydraulic networks. However, the cost of the networks varied depending on the crop scenario. The study suggests that the use of the hydraulic networks would depend on the designer’s interests, and the design and performance of the networks can be influenced by the farm characteristics and the irrigation management.
