- Abstract:

We used the measured data of runoff and sediment discharge the years of Hutubi River Shimen Station in 1980—2011, and analyzed the distribution of Hutubi River sand years and synchronous change rule by using the index coefficient of inhomogeneous, manipulated for monthly and annual variation analysis assisted by using concentration (period) and other methods. The results showed that: (1) the runoff and sediment of different years follow the unimodal type distribution, the distribution and sediment discharge are more concentrated the distribution of the runoff since nearly 32 years; (2) the uneven coefficient of runoff and sediment, completely adjustment coefficient and concentration present the slowly rising trend, and interannual variability of runoff and sediment shows the good synchronicity, runoff and sediment concentration period also has a small upward trend, but the sediment concentration is slightly ahead of runoff because the river supply way and underlaying surface caused by comprehensive effect; (3) The non-uniform coefficient of sediment distribution is significantly higher than the runoff during the year. Complete adjustment coefficient and the change trend of non-uniform coefficient are basically identical. Change of runoff and sediment discharge in winter and spring is out of sync.
