Atrophy of Tail Channels and its Effect on Traveling of Flood in the Yellow River Estuary
Aiming at the problem of atrophy of tail channels after the variation of flow and sediment in the Yellow River estuary, using the methods of field data analyse and theoretical study, the characteristics and mechanism of atrophy of tail channels in the Yellow River Estuary is searched, and its effect on traveling of flood is probed into. Researchful results show that the degradation and aggradation, longitudinal profile, cross section of tail channels experienced readjusting processes, the new evolution characteristics are put up; the variation of flow and sediment molds the atrophic configuration of tail channels, atrophy of tail channels influences the ability of transporting flow and sediment in reverse, which develops the atrophy of tail channels badly; owing to the atrophy of tail channels, the water level of flood elevates, the flood becomes smooth, the flood transmitting time increases, its effect on traveling of flood is very disadvantage. Using the methods of regress analysis, a criterion index of tail channels is erected. It provides referenced use during the process of harnessing the atrophy of tail channels in the Yellow River Estuary.
