Integrated post-event survey of the record-breaking Central Italy flash flood of September 2022: observation strategy and lessons learned

Spatial and temporal scales of occurrence of flash floods, combined with the space and time scale... more Spatial and temporal scales of occurrence of flash floods, combined with the space and time scales of conventional measurement networks of rain and discharge, make these events particularly difficult to observe. The effective documentation of flash floods requires therefore post-flood survey strategies encompassing accurate radar rainfall estimation, indirect reconstruction of peak discharges, field observations of the geomorphic processes and large wood dynamics associated. This also provides ground for quantifying, analyzing and interpreting impacts on communities, infrastructures and ecosystems.This work describes the methods applied and the early results achieved with the survey of the exceptional flash flood that hit the Marche region (Central Italy) between the 15th and 16th of September 2022, with rainfall reaching cumulated local peaks exceeding 400mm and recurrence interval exceeding 500 years for certain rainfall durations. The flood occurred at the end of a climatic anoma...

The storm was concentrated on the Tyrrhenian Sea coast near the city of Barcellona within the Longano catchment. The estimated flood peak discharge of the Longano river in the city of Barcellona (about 230 m3/s for 26 km2) is close to the highest values reported in Europe for similar watershed areas. Rainfall data from raingauge and meteorological radar were analysed and a detailed study of the hydrological response of the catchment was performed by means of rainfall-runoff modelling and flood frequency analysis. The results of the rainfall-runoff model were compared with peak discharges estimated from field observations (cross-sections survey, water marks, witnesses interviews and video recordings). Flood inundation and propagation in the city were modelled using an hydraulic model based on De Saint Venant equation equations calibrated using the data collected (water depths and flow velocities). A geomorphological survey was also conducted to ascertain the evolution of the phenomenon and related sediment processes analysis.

Sub-chapter 2.3.4. Inter-disciplinary post-event surveys to disentangle hazard from vulnerability in the impacts of Mediterranean flash-flood events

The peculiar topography and geographical location of this area make it especially favorable to the occurrence of intense events. The Mediterranean Sea acts as a vast heat and moisture reservoir from which baroclinic atmospheric systems pump part of their energy. The steep orography surrounding the Mediterranean Sea favors lifting of the low-level unstabl..
