El estudio de la variabilidad espacial de específicas magnitudes que caracterizan el suelo no saturado es muy importante para la evaluación de los fenómenos de contaminaciòn. La Geoestadística es una herramienta útil para la estimación de la variabilidad espacial de los parámetros considerados. El objetivo de este estudio es mejorara la comprensión de la variabilidad espacial de la dimensión fractal en las curvas de retención de agua, mostrando de esta manera el comportamiento de este parámetro en los puntos muestreados y demanera particular en los puntos donde no existen muestras. La evaluación de la dimensión fractal se calculó por el análisis de escalamiento obtenido a partir de algunos modelos fractales y la posterior comparación entre los resultados correspondientes.

Abstract
The study of spatial variability of specific quantities characterizing the unsaturated soil is very important for the evaluation of polluting phenomena. Geostatistics is a useful tool for estimating the spatial variability of the considered parameters. The aim of this study is to improve the understanding of the spatial variability of the fractal dimension of water retention curves, showing the behaviour of this parameter in the site examined and particularly at the points where measures were not performed. The assessment of the fractal dimension was calculated by the analysis of scaling obtained from some fractal models and a comparison among the correspondent results was performed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
