In this paper, a new method for solving the parameter estimation problem of water quality model using improved PSO technique is presented. In the improved PSO, the inertial weight decreasing function is a parabola opening upwards rather than the popular linearly decreasing line. In order to demonstrate the scheme, numerical experiments were operated on dissolved oxygen (DO) and biochemical oxygen...
Parameter estimation of water quality model is generally obtained through the comparison of measured histories and model predictions of water bodies. In this paper, we present a new calibration tool of solving the parameter estimation problem by using particle swarm optimization (PSO) technique, which is a swarm intelligence method developed to perform heuristic direct search in a continuous parameter...
