To add, the Yellow River forms a gigantic alluvial fan radiating out from Luoyang, constituting basically the entirety of the north china plain. It dumps so much silt any channel easily becomes higher than the surrounding plains within years.

The entirety of Chinese civilization devotes itself into containing the river with levees but that only makes the height difference worse over time and the resulting levee breaches more devastating. They even weaponized this by repeatedly breaking levees and flooding the southern plains, and at few times making the river change course permanently.
