Abstract：Taking Linjiang River which is a branch of Yangtze River as the research object, one-dimensional water quality model of its backwater reach was created. Finite difference method (FDM) was applied to disperse the variational items of model, water quality model parameters were obtained by adaptive genetic algorithm (AGA). The dispersion coefficients of COD and NH3-N were 0.5227, 0.5196km2/h, the degradation coefficients of COD and NH3-N were 0.0342, 0.0367h-1. The model’s simulated values were in agreement with the experimental value, suggesting the method of FDM-AGA can be used in water quality model parameter identification of branch backwater reach.
