Flash floods - the prototype of methodology and application of the early warning system

Flash floods from the severe storms that have occurred in years 2009 and 2010 brought material damages and risk for the affected areas inhabitants. Flood risk assessment and prediction are well-developed solutions of the natural hazards but flash floods from severe storms are quite complicated issue in the sense of their proper prediction. Flash floods are beyond the resolution of the numerical weather forecast systems (NWFS). Another big issue is fact, that runoff of flash floods is frequently outside of the river channels. The complex and multi-perspective analysis of the landscape response to the severe storm and high-precipitation intensity seems to be effective basis. Results of our work is the prototype of methodology and application of the early warning system based on GIS, hydrological modeling and effective analysis of the radar and NWFS products, which could work in the regional scale opposite to local early warning systems.
