A preliminary analysis directed towards developing a model for the expected areal-average infiltration into a layered soil profile is presented to represent the random spatial variability of the saturated hydraulic conductivity. The basic framework investigated for the model is the one proposed earlier for vertically homogeneous soils, that should be combined with the model for local infiltration into a two layered soil profile. In this context the possibility of reducing the complexity of a local modelling, which relies on the numerical solution of a system of two ordinary differential equations, is analysed by developing parameterized relations for the time to ponding at the surface and the suction head at the bottom of the upper layer.

Abstract
A preliminary analysis directed towards developing a model for the expected areal-average infiltration into a layered soil profile is presented to represent the random spatial variability of the saturated hydraulic conductivity. The basic framework investigated for the model is the one proposed earlier for vertically homogeneous soils, that should be combined with the model for local infiltration into a two layered soil profile. In this context the possibility of reducing the complexity of a local modelling, which relies on the numerical solution of a system of two ordinary differential equations, is analysed by developing parameterized relations for the time to ponding at the surface and the suction head at the bottom of the upper layer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
