Water and sand dynamic simulation method based on bioflocculation
The invention provides a water and sand dynamic simulation method based on bioflocculation. The method includes the following steps that A, initial river way section data are given, the water power factor of each section is calculated according to the upstream boundary condition, the downstream boundary condition and the river way roughness rate, and then water power factor distribution of a whole river way is acquired; B, the water power factors are used for calculating the water turbulent fluctuation shearing rate and then feature data of suspended sand bioflocculation bodies are calculated through the water turbulent fluctuation shearing rate and measured water quality parameters; C, an upstream sand inflow hydrograph, the water power factors of all the sections and the features of the suspended sand bioflocculation bodies are used for calculating scouring sedimentation and moving transportation of the sand bioflocculation bodies of the corresponding sections, and the river way section condition generated after silt is washed away is given; and D, the step A, the step B and the step C are repeated at corresponding time nodes till calculation of a whole period is finished, the whole river way silt washing-away process is simulated, and the evolvement rule of the river way is provided.
