| Abstract Most studies and researches that deal with the effecting factors on wetting pattern under linear dripping source rely on tracing wetting front in two dimensions only. This does not describe the advance of the wetting front in the field by independent or overlapping wetting patterns with three orthogonal dimensions. The current study aims at estimating and observing the resulted wetting pattern from a single emitter on one hand, and the resulted wetting pattern from two neighbored emitters separated by a certain space in three orthogonal dimensions depending on the resulted wetting pattern from a single emitter on the other hand. Six experiments were executed using two water flow rates which are 2.8 and 4.8 let/hr for three cases namely; the single emitter, and two neighbored emitters spaced with 30 cm and 40 cm respectively. The study revealed that the vertical advance at the midpoint of the two emitters increases 100% when the volume of water flow is increased by 75%. It decreases 14% when the water flow rate is increased by 70%. It decreases by 70% when the emitter spacing is increased by 80%.
