5. Conclusions
- (1)
- The ship wave disturbance intensity is greatly influenced by the draft depth, and ship disturbance contributes most of the energy to the horizontal direction rather than the vertical direction, which is manifested by both a longer duration of influence and a stronger turbulence intensity in the horizontal direction.
- (2)
- Compared with the wind-induced wave, the disturbance caused by the ship waves has the characteristics of high intensity, short duration, and narrow influence range.
- (3)
- The maximum total shear stress under ship disturbance can reach 9~90 times the critical shear stress under natural state. At this time, ship waves are the main factor causing sediment resuspension.
- (4)
- Combined with our previous work, the cumulative impact of ship waves on sediment resuspension near the channel of Lake Taihu is much greater than that of wind-induced wave, and may affect the nutrient release and eutrophication in Lake Taihu.
