| Summary: | Peason-III probability distribution is chosen to simulate monthly average
runoff of Panjiakou hydrological station, and calculate the minimum value of
monthly average runoff at different return periods throughout March, April,
May, and the whole spring. The results show that minimum value of monthly
average runoff was 85.59, 62.04, 50.24, 40.74, 30.33, 23.55, and 17.46 m3/s
when return periods were fixed at 2, 10, 20, 50, 100, and 200 years,
respectively. In addition, the fitting results were credible by comparing the
observed return periods. The return periods of monthly average runoff of
Panjiakou hydrological station in March, April, May, and the whole spring of
2001 were 147.00, 254.07, 1.80, and 34.07 years, respectively. |
