reach after
5.And according to the ice slush condition downstream the constructed project in the upstream reach of Yellow River and the ice movement condition in this reach after Wanjiazhai Reservoir construction, we can analysis the influence to the formation of icecap and discharging of ice flow in this reach.
6.Based on the analysis of basic characteristics of Jinghong Reach in the Lancang River, variations of the navigable conditions caused by the regulation project in Jinghong Reach are investigated by 2-D mathematical model. The results show that the navigable conditions in the reach after implementation of the regulation project can basically meet the standards for class-V waterway.
