Abstract：Due to the urbanization and the intensive change of the ground cover in upstream Xiao River area at Yuanwo dam, there were significant corresponding changes in the volume of runoff during observation periods. In particular, there were dramatic reductions in both annual volume of runoff and the maximum of flood peak. At the same time, the pre-designed calculations of the maximum of flood peak were significantly affected by the changed water retain level from the upstream Songta hydropower station. The design and measurements of flood peak are essential to the estimation of both dimension of constructions and investment scale. As a result, the design and calculation of flood peak at Yuanwo dam should be revised to be consistent with the actual data collected during the observation periods. The ideas and methods employed for the re-estimation can be used for reference to the similar constructions.
