       Ship wave and wind wave are the main driving forces for sediment resuspension and endogenous nutrient release in shallow lakes, and also affect the spatial distribution pattern of cyanobacteria bloom. However, the mechanism and mechanism of cyanobacteria bloom are not clear. In this study, we will take Taihu Lake as an example to study the effect of ship wave and wind wave on resuspension of sediment and cyanobacteria bloom in shallow lake. (1) Utilizing the Taihu field observation platform to obtain the time series of the temporal and spatial resolution of the lake water profile before and after the navigation, such as the instantaneous three-dimensional velocity, wave parameters, suspended solids concentration and so on, The hydrodynamic structure of the lake, the sediment resuspension process and the spatial distribution pattern of the cyanobacteria bloom; (2) The mathematic method is used to decouple the weight and relative contribution of the ship wave and wind wave to the lake environment, (3) To develop a multi-component suspended matter mathematical model coupled with ship wave disturbance and wind-induced wave interaction, to simulate and evaluate the effects of ship-borne wave and wind-borne waves on shallow lake Source release and cyanobacteria bloom. The research results provide technical support for shallow water lake ecological waterway construction and endogenous pollution control.

        Taihu Lake water body in the storm, lake and into the lake under the combined effect of the river, with a strong oscillation characteristics. According to foreign research results, the bottom shear stress produced by oscillatory waves is much larger than unidirectional or unidirectional flow, which plays an important role in the erosion of the sediment, but similar studies have not been carried out in Taihu Lake. The project will use the experimental device capable of simulating the oscillatory wave or unidirectional flow of Taihu Lake to study the erosion and transmission characteristics of Taihu Lake and its main sediments in the lake. (1) To study the shear stress of the bottom of the tank under the action of the oscillating wave / unidirectional flow or the different superposition scheme, and study the contribution of the oscillating wave or the unidirectional flow to the shear stress, and establish the empirical relationship between them. (2) To study the erosion rate and transmission characteristics of Taihu Lake and its main sediments in the lake, study the erosion rate and transmission characteristics under different shear stress, and study the contribution of sediment erosion to lake sediments. (3) Based on the measured data of the Taihu Lake area, the relationship between the shear stress condition and the wind direction, hydrological and meteorological conditions in the Taihu Lake area is analyzed, and the experimental results are extrapolated to the practical conditions and factors. The research results can provide important parameters and theoretical support for clarifying the endogenous release and sedimentation and eutrophication mathematical models in Taihu Lake.
