一种河道交汇处岸坡防冲刷的水流调控方法
By constructing a planar flow field model at the confluence of rivers and adjusting the flow rates of the main stream and tributaries, the scouring problem at the river confluence is solved, ensuring the stability of the riverbanks and simplifying the calculations. This model is applicable to the management of river confluences under different conditions.

AI Technical Summary
The complex planar morphology and numerous water flow elements at river confluences, coupled with a lack of effective control measures, lead to severe riverbank erosion, impacting the river's ecological environment and economic development.
By acquiring the basic characteristics of the river confluence, a planar flow field model is constructed, and the flow rates of the main stream and tributaries are adjusted to ensure that the flow velocity on the bank slope is less than the sediment initiation velocity, thereby ensuring bank slope stability.
It effectively solves the scouring problem at river confluences, ensures the stability of riverbanks, simplifies the calculation process, and is applicable to the treatment of river confluences under different conditions.
