Water hammer in irrigation systems

Martina Tadić Ananić, Goran Gjetvaj

Abstract

Self-propelled sectorial rain guns (typhones) and self-propelled automated devices for linear or circular irrigation are often used in irrigation systems. However, unwanted overpressure can occur due to sudden closure of valves at the entrance segment of these devices. The system is protected against such overpressure by gradual closure of valves. The protection of the system against excessive and insufficient pressures, and the impact of simultaneous closure of valves at peripheral parts of the network, are defined in the paper based on an example of hydraulic calculation of unsteady flows at the Blata - Cerna Irrigation System.
