In the present study, the effects of the drag stresss at sea surface (Cd) and bottom (fc) induced by surge and wave interaction on the inundation depth of Typhoon Haiyan were investigated. The error between observations and predictions is estimated up to 90 % when using Cd and fc in comparison to the only Cd and the empirical relation-based drags of sea surface and bottom. In addition, the wave and current interaction-induced sea surface drag leveled off at 25 m/s wind speed is appropriciate when using using Cd and fc. In this condition, it is found that the average Manning number converted from fc corresponds to 0.02.
