Performance of a self-propelled traveler gun sprinkler based on sensor technology

In Egypt, surface irrigation methods are predominantly used for crop cultivation to meet the rising water demand. However, traditional irrigation techniques result in significant water loss. Sprinkler irrigation systems offer a modern alternative that improves water use efficiency by delivering larger amounts of water compared to conventional methods such as flood irrigation. This study evaluated the performance of a traveler gun sprinkler at Aswan University. Field experiments were conducted using nozzle sizes of 8 mm and 10 mm, at a constant pressure of 3 bar, and three forward speeds (25, 50, and 75 m/h). Results showed that the 10 mm nozzle achieved a higher flow rate (6.9 m³/h) and a longer wetted radius (18 m) than the 8 mm nozzle, which had a flow rate of 5.4 m³/h and a radius of 16.25 m. A clear relationship was observed between forward speed and average collected water depth at constant pressure for the two nozzles, with the 10 mm nozzle consistently recording greater values. Shows at 25 m/h, the collected depth was 6.61 mm for the 10 mm nozzle compared to 5.1 mm for the 8 mm nozzle.
