It is impossible for the Yangtze River and the Yellow River not to flow into the sea. Unless the glaciers don't melt, the seawater doesn't evaporate, and the precipitation doesn't circulate, the water supply sources of the Yangtze River and the Yellow River decrease, or according to the topography and annual runoff that the Yangtze River and the Yellow River flow through now, the water overflows? There is a truth. When the Yangtze River water and Yellow River water reach a certain peak, they will definitely leak out and inject into the sea. The Yellow River basin flows through Bayan Kara Mountain Range, Qinghai-Tibet Plateau, Hexi Corridor, Helan Mountain Range, Inner Mongolia Plateau, Loess Plateau, Taihang Mountain Range and North China Plain, and finally flows into Bohai Sea. The terrain along the two rivers is likely to form a big lake, but it is impossible to stop the Yangtze River and the Yellow River from flowing into the sea.
For the utilization of the Yangtze River and the Yellow River, it is not necessary to store all the water, but on the basis of flood control, irrigation utilization, domestic water supply and power generation. What should flow into the ocean will flow into the ocean, which is also the law of natural circulation.
River water evaporates in the process of flowing into the ocean, and seawater evaporates into steam, which is transported back to land to realize water circulation.
If the water from the Yangtze River and the Yellow River does not flow into the sea, it will seriously affect the ecological laws of nature. Forcibly destroying the water cycle has a great impact on the dynamic balance of global water and will affect the normal operation of nature.
