Abstract

A proper understanding of factors affecting water distribution UNIFORMITY in SPRINKLER IRRIGATION is important for developing water conservation strategies. The purpose of this study was to determine UNIFORMITY in semi-portable SPRINKLER IRRIGATION system under different WIND speed. The main factors affecting UNIFORMITY (i.e. sprinkler spacing and layout and WIND speed) with this system were analyzed. The standard ISO 7749/2 has been taken into account to determine UNIFORMITY. The type of field test was conducted under single sprinkler condition in south-east region of khouzestan province. The investigations showed that higher CD values are attained with square-shaped spacing. Results also showed that UNIFORMITY decreased as WIND speed increased under all options of SPRINKLERS LAYOUT AND SPACING. The most suitable sprinkler spacing in order to obtain acceptable UNIFORMITY (80%) seems to be to locate sprinklers 25x25m when WIND speed are higher than 2m/s.
