Abstract
An overview of the local infiltration modeling for soils under regular and erratic rainfalls is presented. For homogeneous soils, some remarks concerning the main classical approaches, widely used for isolated storms under the condition of soil infiltration capacity not exceeding the rainfall rate, are first performed. Then, an exhaustive analysis of the modeling formulated by Corradini et al. (1997) [Journal of Hydrology, 192:104-124] is carried out. The model represents appropriately the infiltration under any rainfall pattern, including also periods with redistribution of soil water and reinfiltration, and is therefore more general than that proposed earlier by Dagan and Bresler (1983) [Water Resources Research 19(2):413-420] using a similar starting point represented by a combination of depth-integrated forms of the continuity equation and Darcy’s law. Considering that many natural soils can be schematized by two-layered soil profiles, after a short discussion about the characteristics of a soil profile with a sealing layer on the parent soil and the linked classical models, the more general formulation proposed by Corradini et al. (2000) [Journal of Hydrology, 237:58-73], that is and applicable during arbitrary rainfall patterns over any two-layered soil combination where either layer may be more permeable, is examined.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
