Evaluating and modeling solid-set sprinklers irrigation of the field borders

TL;DRAbstract

Numerous studies have analyzed the solid-set sprinkler irrigation system performance. However, in the literature the effect of the field borders irrigated by no-complete circle sprinklers has not been considered in the whole-field performance. The objectives of this study are 1) to characterize two different solutions to irrigate the field borders (full circle sprinkler equipped with a deflecting plate, DP, and partial circle sprinklers, PC); and 2) to calibrate and validate a ballistic model (Playan et al, 2006) to adequately simulate their functioning. Two types of experiments were designed. The firsts were carried out with an isolated sprinkler under no windy conditions and at three pressure levels (200, 300 and 400 kPa). The second experiments were performed in a square solid-set sprinkler layout (18 m by 18 m) under three operating pressures (200, 300 and 400 kPa) and two levels of wind speed (lower than 2 m s and between 2 and 4 m s
