Models of water infiltration in soil that depend on a single data or measurement, such as those of Kostiakov, Philips, Horton, and Green and Ampt, do not consider the influence of surrounding trees. The hypothesis in this study was that this can influence the generic values taken in the field, and therefore, these values should be corrected. The following are factors that can have an influence: tree species, distance
to trunk, tree height, and management (cultivated or not). Infiltration was measured with a double-ring infiltrometer at several distances from the trunk of three species of trees cultivated under irrigation: Citrus sinensis, Citrus limon, Olea europaea, another three forest species: Eucalyptus globulus, Pinus halepensis, and Tamarix canariensis, bare ground and continuous grass (Zoysia spp) cover. After fitting the different models and using hydraulic conductivity as a parameter for this study, it was demonstrated that it is
necessary to correct infiltration parameter...
