| Summary: |
Solid-set sprinkler irrigation has been widely used around the world. The use of high
operating pressure in the operation of sprinkler irrigation system is most prevalent
than the use of low operating pressure. Some researchers attempted to use the low
operating pressure in some types of sprinkler irrigation system such as center-pivot
system. However, the use of low pressure in solid-set sprinkler irrigation is still not
applicable. This research aimed to investigate the irrigation uniformity of solid-set
sprinkler irrigation using low operating pressure. This study further aimed to develop
better understanding about the effect of design factors on irrigation uniformity.
Furthermore, to find the relation between water application uniformity on the soil
surface and soil moisture distribution uniformity in two soil layers. Two solid-set
sprinkler systems, square (12x12 m) and rectangular (12x10 m) were designed.
Different low operating pressures (62, 82, 102, and 122 KPa) with different nozzle
diameters (4, 5, 6 and 7 mm) and riser heights (0.5, 0.75 and 1 m) were used. |
