Abstract
In order to predict volumetric water content, it is necessary to know the water retention curve in the soil, as well as the hydraulic conductivity function. These functions depend on parameters related to the soil physical characteristic such as texture. It is in this sense that the aim of this work is to compare the three versions of the Luus-Jaakola method.
