This paper combines hydrometeorology and social science in an effort to better understand social vulnerabilities to flash floods. The authors argue that integrating these two fields can substantially improve the understanding of public responses, which may ultimately reduce losses of life. Hydrometeorological advances have allowed for more accurate predictions and increased lead times, yet social vulnerabilities still prove to be an issue. Thus, the integration of hydrometeorology and social science is crucial in order to better understand both the hydrometeorological circumstances as well as public behavior during flash floods. The September 2002 flash flood that occurred in Southern France acts as a case study. Using information and experience from this event, a combination of human and physical analysis are carried out via simulations and interviews. Findings reveal that small catchments are more dangerous and post-event analysis requires further investigation.
