| Zusammenfassung |
| Hydrometeorological analyses of rainfall and flood response are presented for the flood event occurred over the Veneto Region (North-eastern Italy) in November 2010. The event – lasting three days - produced localized storm total rainfall accumulation exceeding 500 mm. Hydrometeorological and hydrologic studies illustrate the important role of orography in controlling the flood response. Analyses of high-resolution radar rainfall fields are presented, with special emphasis on radar rainfall error structure and spatial and temporal variations of flood-producing rainfall. Diagnostic and hydrologic model studies in the Posina, Leogra and Agno basins are carried out to examine the controls of land surface processes and space-time rainfall distribution on extreme flood response. Land surface processes and the contrasting distribution of rainfall in space and time from the storm systems combine to shape the scale-dependent distribution of extreme floods in the study basins. |
