The main goal of this paper is to present a hydro-meteorological assessment of the last three major floods observed on the small coastal watersheds of the French Riviera (October 3, 23 November 2015, 2019 and 1 December 2019). The joint analysis of precipitation data from rain gauges and of several quantitative precipitation estimates products...
Study region: eastern part of the French Mediterranean coastal area. Study focus: This work focuses on the heavy precipitation events that have affected the eastern part of the French Mediterranean coastal area over the last decade and the river discharges associated with these events. The aim is to make a throughout analysis of the...
Plusieurs épisodes pluvieux particulièrement intenses se sont succédés sur le département des Alpes-Maritimes depuis quelques années, impactant différents bassins versants par le ruissellement et le débordement soudain de cours d'eau. Les conséquences associées sont des dégâts colossaux (plusieurs dizaines de décès et des centaines de millions...

Flash-flood modelling is of utmost importance in order to forecast the extent of a potential heavy rainfall event. With the development of new flood forecasting tools, we are getting closer to real-time flood modelling goals. In small highly urbanized catchments and under extreme hydrological events, culverts may not be able to convey the...

The French Riviera, located in the eastern part of the French Mediterranean coast, has experienced devastating flash floods during the last 10 years. Several of these floods were generated by local and very intense rainfall events, leading to significant material and human losses, especially on small coastal catchments, which often have sparse...
The short and heavy rainfall events observed on the French Riviera often lead to flash floods on coastal catchments: during the flood of 2 October 2015, a peak discharge between 185 and 295 m3/s was estimated on the Brague at Biot at 8:00 PM, whereas the flow rate was about 1 m3/s at 5:30 PM there. While measurements of such discharges are very...
Short and heavy rainstorm events often lead to flash floods on the French Riviera coastal catchments: during the historical 2nd October 2015 flood, a peak streamflow value between 185 and 295 m3/s was estimated on the Brague River at Biot at 10:30 P.M., while the streamflow was around 1 m3/s at 6:30 P.M. at the same section. If the measurements...
