- Abstract:
- During the ice flood of the Yellow River, expansion and contraction of the river leads to riparian changes, affects the ecological water of plants in the coastal and desert sand flow into the river. We analyzed the dynamic change of the River ebb and flow dynamic process and its influencing factors during 1989—2010 between Wuhai hydro-junction to Sanshenggong. The results show that the water level change trend is shrinking-expansion-expansion-contraction during the summer of four periods. On the left bank, the banks show a trend of shrinking and shifting to the right when it mainly shifts to the right. On the contrary, when the river bank shifts to the left on the left side, and the right to the right, river bank shows a trend of expansion. In winters of three periods, the left river bank shifts the left, and ice shows contraction-expansion-contraction trend. The river bank shows the right deviation trend when the river is shrinking. On the contrary, the river bank shows the left deviation trend when the river is expanding. Compared with flood period in summer, winter icy period on the left bank is given priority to sifting to the left, right bank is given priority to sifting to the right, and on the left bank shift extent is significantly greater than that of the right. Through the correlation analysis, change of river bank and upstream rainfall are significantly correlated in summer, but in winter, the water level change is related to downstream temperature difference and the left bank terrain of Ulan Buh Desert in the Yellow River.
