ABSTRACT

Rainfall runoff models have been used as main tool for water management in the catchment. The majority of the practical models in water managements are a type of conceptual models. This study aim to define relationships between characteristics of short term flood events and calibration of the ReFH(Revitalized Flood Hydrograph model). Ten flood events of Jeungpyeong in the period of 2000 and 2013 are analyzed with model performances and characteristics of flood, such as the maximum rainfall intensity, runoff ratio, peak rainfall-flood time difference and etc. the. The results indicate that a larger quantitative magnitude of the event(flood peak, maximum rainfall intensity, etc.) better performance in calibration. However, prior rainfall to flood events does not show a clear correlation. The calibrated parameters of the model(i.e., Cmax,) of flood events are consistent, which reflect the unique characteristics of the watershed. The results of this study are used as a basis for future studies of regionalization of rainfall runoff model for Geum river region.
