Wind speed’s impact on the distribution uniformity of sprinkler irrigation system in Haryana

Abstract

This study investigated the impact of varying wind speeds on water distribution uniformity using a 6 m × 6 m lateral spacing configuration with rotating sprinklers at the field of the village Luhana located in Western Haryana, India, during 2019-20. Three replications were conducted under different wind conditions: 0-4 km/h, 4-8 km/h, and 8-12 km/h. For wind speeds ranging from 0 to 4 km/h, observed speeds averaged 3.0 km/h, with distribution uniformity ranging from 79.17% to 86.33% in the northwest direction (average 82.46%). Wind speeds between 4 and 8 km/h yielded an average of 6.4 km/h, with distribution uniformity varying from 81.42% to 84.22% (average 82.88%). At wind speeds of 8-12 km/h (average 10.8 km/h), distribution uniformity ranged from 79.73% to 83.57% (average 81.42%). Variations in the uniform distribution of water were less prominant at wind speeds between 0-4 km/h. But it was observed that a range of wind speed 8-12 km/h, significant deviation from the uniformity distribution of water was observed.
