A flood warning system based on rainfall thresholds makes it possible to issue alarms via an off-line approach. This … rainfall thresholds. Critical precipitation amounts are evaluated using empirical data, hydrological simulations and …, historical data are first used to theoretically evaluate the empirical rainfall thresholds. Next, we calibrate a semi …

Rainfall thresholds for flood triggering. The case of Marathonas in Greece

Diakakis, Michalis - In: Natural Hazards 60 (2012) 3, pp. 789-800

Basins across Mediterranean coast are often subject to rapid inundation phenomena caused by intense rainfall events. In this flash flooding regime, common practices for risk mitigation involve hydraulic modeling, geomorphic, and hydrologic analysis. However, apart from examining the intrinsic...

Rainfall intensity–duration thresholds for postfire debris-flow emergency-response planning

Cannon, Susan; Boldt, Eric; Laber, Jayme; Kean, Jason; … - In: Natural Hazards 59 (2011) 1, pp. 209-236

Following wildfires, emergency-response and public-safety agencies can be faced with evacuation and resource-deployment decisions well in advance of coming winter storms and during storms themselves. Information critical to these decisions is provided for recently burned areas in the San Gabriel...
