Water pollution estimation based on the 2D transport-diffusion model and the Singular Evolutive Interpolated Kalman filter Estimation de la pollution de l'eau basée sur un modèle 2D de transport-diffusion et sur le filtre de Kalman singulier évolutif interpolé

摘要

In this paper, the 2D mathematical water pollution model describing the transport- diffusion processes of some contaminant substances in Thanh Nhan Lake in Hanoi is considered. The finite-volume method is used to solve the model equations. The Singular Evolutive Interpolated Kalman filter is applied to evaluate the pollution level at arbitrary mesh point based only on a small number of measurement points.
