Abstract

A set of experiments was conducted to investigate the wetting contours obtained under very low pressure (10–15 kPa) moving emitters. Nine different instantaneous application rates (IAR) were applied by three types of emitters: open-end pipe, short (5 m) and long (10 m) perforated pipes and for three water amounts. Results show that high IAR increase the uniformity of the wetting pattern and its width, and decrease the depth. On the other hand, high IAR increase water ponding on soil surface and, consequently, water runoff. The results of wetting patterns under moving emitters are in a good agreement with those for source-point stationary emitters.
