In this paper, a new evaluation method of flood mitigation function was proposed. It defined that with this method the flood mitigation function means averaging the rainfall-runoff. Moreover, it is shown that the amount of averages is related to the amount of peak discharge reduction. Therefore, this relation was defined as averaging time. The averaging time can be found by the accurated rainfall method and the moving average method. Furthermore, it is applicable to evaluation of the amout of peak discharge. Therefore, the concept of this averaging time can evaluate the flood mitigation function. It is shown that this evaluation method is a method effective in evaluation of the flood mitigation function in small catchments and irrigation pond basins.
