Description

A multilinear stage-hydrograph routing method using the diffusion analogy model as a sub-model is proposed in this study. The diffusion analogy model can be considered as the next level of approximation to the full Saint-Venant equations. The applicability of the method is tested by studying flood wave propagation in the 15 km Pierantonio-Ponte Felcino reach of the Tiber River in Central Italy. The results demonstrate the suitability of the diffusion analogy model as a sub-model for its use in the multilinear flood routing method for field applications.
