The information of depth and width in wetted zone soil under drip irrigation plays great significance in design and management in the irrigation system for the amount of water required to the plant. For that, six experiments were installed in different soils with the objective of evaluating the dimensions of the wet bulb in the drip irrigation depending on the emitter discharged and of the water application time, using the power model. The obtained results showed that the proposed model can be used to estimate the dimensions of the wetted bulb for the all soils.
