Abstract

Information on the geometry of wetted soil volume under trickle irrigation is important for design and operation of this irrigation system, and also for the management of the irrigation. For this, six experiments were installed in different soils with the objective of evaluate the dimensions of the wetted bulb as function of emitter discharged and water application time, using the power model. It was concluded that the wetted bulb dimensions can be predicted satisfactorily using the power model for all the soils tested.
