ABSTRACT. – Flash floods as natural hazards in Hungary, with special focus on SW Hungary. Flash floods are increasingly frequent natural hazards in Hungary. Record precipitation values in Hungary in May and June, 2010, underline the importance of the modeling of the extension of inundations and the prediction of flood events. This paper summarizes the concept of flash floods from hydrological and meteorological approaches and, shows an example for the application of rapid screening, GIS and numerical modeling in Southern Transdanubia.
Key words: flash flood, modeling, rapid screening, prediction system, GIS
