| Abstract | Regionalisation flood models, developed last years in Cemagref (Lyon department) allow us to characterise, with Flow(Q)-duration-Frequency curves, the flood hydrological regime of catchments gauged or not. These models, named QdF, and particularly those developed from the analysis of threshold discharges, characteristics of the flow regime, also allow us construction, for a given site, of a Mono-Frequency Synthetic Hydrograph (MFSH), the volume of which being consistent with the flow regime. Because of their spatial representativity and their scale integration (both in area and in duration), QdF models in threshold discharge can be used to establish MFSH on small mountainous basins with rapid runoff So we present these models and the validation results obtained on the basins ofLe Laval (0.86 km 2 ) and La Roubine (1,330 m 2 ), ERB of Draix. QdF models, characterising flood regime in every point of a river and expressing some social need, are favoured operational tools in integrated basin hydraulic modeling. |
