Continuum (Silvestro et al., 2013) is a continuous distributed hydrological model that strongly relies on a morphological approach, based on a novel way for the drainage network components identification (Giannoni et al., 2005). The model is a compromise between models with a strong empirical connotation, which are easy to implement but far from reality, and complex physically based models which try to reproduce the hydrological processes with high detail but which introduce a hard parameterization and consequent uncertainty and lack of robust parameters identification.

The Continuum model aims at an equilibrium between simplicity and rigorous physical modeling while maintaining comparable performances to existing models; the reduced complexity of the schematizations and the relatively small number of parameters leads to a considerably lower calibration effort, increasing model robustness and portability to data scarce environments. The resulting increased computational efficiency leads to an easier utilization of the model in ensemble mode so that a direct quantification of prediction uncertainties is possible. All the main hydrological phenomena are modeled in a distributed way.
