风、浪、流共同作用下的泥沙输移

Sediment transportation under wind, wave and tidal current

根据波动水流能量及泥沙运动原理,参考了窦国仁推导底沙输沙量的方法,推导出波浪、潮流和风吹流共同作用下的底沙输沙量(包括推移质和部分悬移质输沙)计算式.应用于大风期黄骅港外航道的骤淤计算,其结果与实测值较接近.

According to the theories of the energy dissipation of wave-water and sediment movement and based on the bottom sediment load formula developed by Dou Guoren, a formula to calculate the transport of the bottom sediment, which includes the bed load and part of suspended load, under the joint action of waves, tidal currents and wind-currents is derived. The formula is used to calculate the sudden siltation amount in the access channel of Huanghua Port in the gale period, and the calculation results are close to the measured values.
