Study on Parameter Optimization of Water Quality Simulation of Multi-reservoirs

In order to establish water quality simulation model which is more accurate and applicable to the actual problems, the optimal principle of valuation for water quality multiple parameters is used to optimize the model parameters. Taking multi-reservoirs of the raw water system in Shenzhen City for an example, a valuation model of multi-parameters optimization is established. In addition, based on the particle swarm algorithm, the parameters of the simulation model for water quality of multi-reservoirs are optimized. The calculation result shows that the water quality parameters obtained by this model is reasonable and feasible. Besides, the model accuracy can meet the engineering application requirements, which provides important reference basis for joint regulation of water quantity and quality of city raw water system.
