Abstract:

Taking Three Gorges Reservoir as an example, the flood entering into the reservoir was analyzed according to the characteristics of rainstorm and flood and regional flood composition. By using different influential factors such as the peak pattern, flood storage capacity and regional flood composition, the flood was classified by projection pursuit method. It is shown that the classified flood into the reservoir are well related with dam site flood with high correlation coefficient, which can be used to convert the dam site flood to the flood entering into reservoir. The results can provide scientific support to practical reservoir operation.
