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.
