Abstract
Travelling gun irrigation is a popular form of irrigation in the Queensland dairy, sugar and horticultural industries. High uniformity of irrigation applications is essential to the production of high yields from these crops however, poor uniformity is characteristic of travelling gun machines. For example, Smith et al. (2002) reported that only 25% of machines tested in sugar cane areas near Bundaberg, Qld, gave uniformities greater than the recommended Christiansen Coefficient of Uniformity (CU) of 80%. Simulation of the sprinkler distribution pattern from a travelling gun provides the basis for a powerful and effective decision support model for these machines that will assist extension staff in the development and promotion of optimum irrigation management strategies. Central to the simulation is the prediction of the impact of wind on the sprinkler patterns.
