The main objective of this study is to evaluate the performance of
different sprinkler types under two water qualities and four levels of
..
operating pressure at ELREHAB city. For this purpose, three sprinkler
types were selected and the operating parameters were evaluated The
results showed that for treated waste water (TWW) the best value of
Christiansen Coefficient of Uniformity (CUC) and Distribution
Uniformity (DU) were 86.83% and 78.11% respectively that was for
(LPS) sprinkler at operating pressure 3.5 kPa. And the results showed that
for fresh water (FW) the best value of(CUC) and (DU) were 77.22% and
66.42 % at operating pressure 2.8 and 2.1 kPa for (PS) and (PSU)
sprinkler respectively. The analysis presented in this study may serve to
develop a decision tool to choose the most suitable combinations of
sprinkler model, nozzle diameter and working pressure to optimize the
uniformity and efficiency ofsprinkler irrigation.
