This study aim to assess the relationships between calibrated model parameters of catchment rainfall renoff model and flood characteristics of 15 flood events at Cheoncheon catchment, Yongdam. Three model parameters, SCS-CN, Tc and Sc of Clark Method, are plotted against maximum rainfall intensity and runoff ratio of flood events. Althought SCS-CN has strong relationship between runoff ratio, there is no strong realtinship for Tc and Sc. this study suggest Tc model parameters are more influenced by catchment hydrological characteristics of flood events. Further study will suggest Tc as a physical charaterisc of catchments by increasing flood events analysis.
