Sobre la relación entre las distribuciones de los tamaños de poros y partículas del suelo

The particle and void sizes distributions of the soil are related with the assumption that a void constant relationship at all different scales and a relationship between pore and particle size of a given packing. In the relationship between pore and particle sizes, a particle elongation factor is applied based on the Arya and Paris model. A flow trajectory tortuosity factor based on the Fuentes model can also be applied. Since the void size distribution is associated to the soil water retention curve, the proposed relationship can be used to estimate this curve from particle size distribution.
