HYDRATE - Analysis of major flash flood events

The report describes results of the project Hydrate to improve understanding of the relative role of meteorological and hydrological processes in flash flood generation. This was done by (i) an analysis of the meteorological patterns and kinematic/microphysical characteristics associated to the major flash flood events; (ii) examination of the space and time scales required for distributed flash flood modelling and analysis of the hydrologic response as function of the space-time structure of rainfall; (iii) a sensitivity study on the influence of initial conditions, and investigation of the dominant flash flood hydrological generating processes, as a basis for regional modelling; (iv) coupling hydrology and shallow landsliding through investigative models; (v) analysis of impact of attenuating river reaches and overflowing on flood propagation, including the influence of debris and channel change.
