Abstract
Based on the hydrodynamic model of the Charysh River section, the calculation of the direct and inverse problem of determining the total mass flow rate of a conservative pollutant under various scenarios of diffuse pollution was carried out. The calculation of the inverse problem was performed using nonlinear global optimization and Monte Carlo methods based on a polynomial representation of the distribution of the total mass flow rate. A satisfactory agreement between the reconstructed and initial distributions was established, and an estimate of the effective value of the Peclet number was obtained. It was found that the value of the effective Peclet number is within the range of its real change.
