According to the characteristics of uneven distribution of precipitation in the Li Xianjiang River Basin in the region and season, the causes, process and hazards of a larger flood occurred in the special flood season of the Li Xian River Basin - the latter flood season were analyzed. The case of making full use of flood control capacity of middle and upper reaches reservoirs in cascade reservoirs to improve flood control capacity of downstream reservoirs is described. The problems that should be paid attention to in the regulation of cascade reservoirs are pointed out, which is of reference for flood control dispatching in cascade reservoirs.
