        ABSTRACT. Collecting and employment of soil parameter for numerical flash flood modeling in ultra-small watersheds. Thunderstorms and other catastrophic whether phenomena more frequently occur over the past decades in Hungary. Their consequences, such as flash flood have been causing economic losses with an increasing frequency lately. The most hazardous areas are the mountainous-, and low-hilly areas. Numeric runoff models are essential tools for the prediction of flash floods. However they require several initial boundary condition parameters, among which soil data are indispensable elements. In the present study, we present the employment soil physical and precipitation data collecting methods from a pilot catchment in SW Hungary for runoff simulation and interpret their efficiency.

 

Key words: flash flood, soil moisture, soil thickness, numeric modeling
