It has had many disastrous floods; irrigation and flood management tasks have been occurring in the area for several thousand years and have never achieved complete success. The defenses need continuous maintenance and re-modeling as the silt builds up within the channel high above, if the river flowing excessive above bursts its levee then widespread flooding could be inevitable. Its basin space is 752,443 km2 , containing about 200,000 km2 of arable land and over one hundred million folks. The name “Yellow River” comes from the huge amounts of “yellow” loess sediment it carries when flowing by way of the Loess Plateau. It is the world’s main river with the most extreme siltation.
The current mouth of the Yellow River is situated at Kenli County, Shandong. The headwaters of this mighty river are positioned in the Kunlun Mountains in northwestern Qinghai Province. Going south, Shanghai via Suzhou could be the plain route but there are lots of different decisions.
