River course and flood season mass-flow, reservoir joint debugging sand discharge enter sea, are the methods improving sand discharge efficiency;" putting ", " digging " are to take out sand to make ground, dig
River silt is carried on the back, and is the supplement reducing In The Lower Yellow River alluvial.In terms of reality, these measures all can not fundamentally change Huang
The long-term trend problem that river downstream sediment alluvial riverbed is raised.
One of current and later the Yellow River is mainly characterized by only before and after flood season just having compared with mass-flow, could efficiently arrange
Sand, and in the most of the time, the little flow velocity of flow is slow, and silt particularly bulky grain silt in riverbed was then difficult to start in this stage,
Sedimentary loading is little.And build through Upper-middle Reaches of The Yellow River extensive dam storehouse group, the Yellow River has been carried out whole year and does not stop, and with new
Ba Ku build up, the Yellow River non-flood period flow controls must be more preferably more preferable.Improve the Yellow River full-time sky sediment transport efficiency imperative, special
Be not improve the Yellow River " little water " stage sand discharge efficiency space huge.
