The lower Yellow River is a world-renowned suspended river

and is also the key point in the governance of Yellow River. Water and sediment regulation scheme based on the Xiaolangdi Reservoir has achieved remarkable success within the past 20 years

with overall channel degradation of the lower Yellow River as well as the formation of middle-water channel. However

the governance of the lower Yellow River also encounters new challenges

including dramatically changing water and sediment situation

reduction in channel degradation efficiency

and insufficient subsequent power of the Xiaolangdi Reservoir. Based on the above background

this article systematically reviews the research results on the water and sediment situation

river evolution

and systematic governance of the lower Yellow River since the operation of Xiaolangdi Reservoir. On this basis

it suggests that in the future

in-depth research should be carried out on the evolution laws and water and sediment regulation of the lower Yellow River

the engineering system for water and sediment regulation in the lower Yellow River should be improved

and river management models in the lower Yellow River should be explored and innovated.
