The Research On Dam Break Models And Controlling Problems Of Hongze Lake Under Dam Break Flood Continuous Interference

For the study of Hongze-lake Dam-break problem, it is mainly based on the five stepmodeling method and the model predictive control principle for mathematical modeling of theHongze lake dam-break problem, and use the control toolbox in Matlab to solve the problem.For the study of Hongze-lake Dam-break problem, it starts from the one-dimensionalSaint-Venant hydrodynamic equations. Then give out the continuity interference factor of wateraccording to the hydraulics principle and use the well-known Preissmann four point implicitmethod to solve Saint-Venant equations. And then solve out the dam-break flood flow、the depthat the dam site、the dam site、the flowing velocity and the water depth at dam site based onMatlab and continuous water interference effects. Finally,starts from the CARIMA model,basedon the Kalman filtering method and combined with the measured data of Jiang Dam in HongzeLake.I get the time domain analysis diagram and the the leval changes of water diagram on theapplication of the Matlab control toolbox. The results which we obtained provides realistic basisfor the present study of this thesis.
