It was proved that there were liquidity constraints depending on the amount of damages in property incurred by the affected households in relation to their financial assets.　A method is proposed to estimate the duration of post-flood recovery required to calculate the amount of the loss from liquidity constraints. With regard to psychological damage, the relationship between the depth of inundation and the magnitude of the psychological damage, and its temporal change are considered in the calculation.　As a result, it was found that psychological damages consist of the damage that fades over time, and the one that affects the victim for a long period.　A method to quantify the damage based on this constitution is also proposed.　In this study, a direction is presented for future economic survey on flood control to evaluate the effectiveness of flood control measures that cannot be estimated by conventional methods focused on property damages.　In addition, the considerations for obtaining more accurate information on flood damages are also pointed out.
