Abstract

The aim of this research was to evaluate the performance of two types of floppy sprinklers, original type and local type to determine optimum operating conditions that achieve high application efficiency. The coefficient of uniformity (CU), distribution uniformity (DU) and application efficiency of low quarter (AELQ) were evaluated under different levels of operating pressure and riser height. It was concluded that the operating conditions that achieved high coefficient of uniformity, distribution uniformity and application efficiency of low quarter were operating pressure of 200 kPa and riser height of 2.0 m for both types of floppy sprinklers. The corresponding values of CU, DU and AELQ were 70.65, 52.59 and 44.33 % for original and 66.67, 44.31 and 37.46 % for local, respectively. Also, to achieve high percentage of overlap simulation model was used, it appeared that the spacing between sprinklers should be higher than or equal 50 % of wetted diameter to avoid water lose and minimize irrigation system cost.
