الوصف: A global space-time MQ collocation method is used to solve an inverse problem of 2D unsteady pollutant transport in steady flow, and the initial distribution of pollutant concentration is reconstructed from observation data with a certain level of noise. A cross-validation technique is used for estimation of optimal model parameters. Application of this method in case studies of diffusion and advection-diffusion under different boundary conditions show that in different scenarios the initial concentration distribution can be accurately estimated and that for input noise levels 0.5 and 1.0 the calculation errors are 0.0361, 0.0357, 0.0419, 0.0453 and 0.0712, 0.0695, 0.0503, 0.0703 respectively, all lower than the corresponding input noise level.
