Flash Flood Indicator
Popis výsledku v původním jazyce
This work deals with developing an operational approach to utilize the current possibilities of rainfall-runoff modelling for determining the risk of occurrence of flash floods in real-time. This piece of research and development was inspired by the basic research reported in providing the Flash Flood Guidance (FFG), operated by the US National Weather Service (NWS) . Its main output is the amount of rainfall of a given duration that is needed to cause bank-full conditions in smaller watercourses in the region, being dependent on the antecedent soil moisture conditions. This critical precipitation is termed the Flash Flood Guidance. The research undertaken by the CHMI has resulted in development of a system that produces the Flash Flood Indicator that has been given the acronym FFI. The system FFI consists of the following main components: – calculation of the current soil moisture conditions over an area in a daily step based on the water balance of rainfall, runoff and actual evapotranspiration, – calculation of potentially dangerous amounts of rainfall of durations of 1, 3 and 6 hours, which may cause significant surface runoff, – an estimate of the general flash flood risk based on 10-minute radar rainfall estimates (including nowcasting) and defined runoff thresholds. The general flash flood risk is computed as a combination of the local flooding risk and the flash flood risk by using the schematic of hydrologically connected river basins and reaches. The authors plan to update this document depending on the future development of the Flash Flood Indicator.
