| Abstract: | A new approach based on genetic algorithm for multi-parameters inversion of BOD-DO water quality model is proposed.It transforms the parameter inversion into solution of optimization problem using genetic algorithm.By using genetic algorithm the method can search the best solution from many initial points and obtain the total optimum solution of BOD-DO water model parameters by means of crossover and mutation operator.The results of numerical simulation show that the method has higher accuracy and quicker convergent speed than existing methods and is easy to program and calculate. |
