The soil moisture controls the partitioning of rainfall into runoff and infiltration and, hence, the runoff generation.

Abstract

The soil moisture controls the partitioning of rainfall into runoff and infiltration and, hence, the runoff generation. At catchment scale its routinely measurement can be performed by remote sensing technologies. In this context, the purpose of this study is to investigate the potential of the Advanced Microwave Sounding Unit radiometer (on board of the NOAA satellites) for the wetness conditions assessment at the catchment scale through the comparison with soil moisture data provided by a continuous rainfall-runoff model applied to four catchments located in the Upper Tiber River (Central Italy). In particular, the Soil Wetness Variation Index, modified for taking into account of the soil layer affecting the rainfall-runoff transformation, was found correlated with the modeled soil moisture variations.
