- •
To predict the soil volume wetted by a single emitter on the ground surface.
- •
Humidified bulb corresponds to the soil volume delimited by the wetting front.
- •
The developed equation fulfils the boundary conditions for an axisymmetric flow.
- •
The knowledge of Kf, θf and θi allows the inference of maximum wetting front position.
