Water Pollution Source Localization Based on the Contour in Sensor Networks

To make up the shortcomings of the coarse pollution source localization algorithm and the localization methods based on the diffusion models in water, a pollution source localization algorithm based on the concentration contour is proposed. In the method, the location of the source is obtained according to the geometrical configuration feature of the contour. In the simulations, based on the simulation data of MODFLOW, the proposed localization method is tested and compared with the localization methods based on diffusion models and the CPA(Closest Point Approach) localization method. The results show that the performance of the proposed algorithm is better than the other two methods when the concentration contour is axisymmetric.
