Rainfall-runoff modelling is a relevant topic in water resources management in particular for small and ungauged basin; nowadays starting from Digital Elevation Models (DEMs) and assuming that the watershed's runoff response is linear and time-invariant, it is possible to determine the hydrograph corresponding to any given rainfall excess optimizing the geomorphological information provided by the basin topography: in the present work a case study is discussed within the framework of the Width Function Instantaneous Unit Hydrograph (WFIUH), i.e. a basin characteristic that can describe, using just one parameter, the spatial distribution of residence times.

Abstract
Rainfall-runoff modelling is a relevant topic in water resources management in particular for small and ungauged basin; nowadays starting from Digital Elevation Models (DEMs) and assuming that the watershed's runoff response is linear and time-invariant, it is possible to determine the hydrograph corresponding to any given rainfall excess optimizing the geomorphological information provided by the basin topography: in the present work a case study is discussed within the framework of the Width Function Instantaneous Unit Hydrograph (WFIUH), i.e. a basin characteristic that can describe, using just one parameter, the spatial distribution of residence times.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
