本文针对广西岩溶地区小型水库水文地质资料缺乏、地下水分水岭难以确定、无通用岩溶区产汇流模型的特点,提出由实测暴雨资料及相应库水位观测资料模拟遭遇大洪水时的水库调洪过程,反推伏流暗河区洪峰流量,从而计算出相对可靠的水库设计洪水。 In view of the lack of hydrogeological data and the difficulty of determining the groundwater watershed in the small reservoirs in the karst area of ​​Guangxi Province, this paper proposes a method to simulate the process of flood control in the event of a big flood, based on the observed storm data and the corresponding reservoir water level observation data Inverted torrent river flood peak flow, in order to calculate the relatively reliable reservoir design flood.
