Целью работы является применение методики определения полного массового расхода консервативного загрязнителя и эффективной величины числа Пекле при различных сценариях диффузного загрязнения. На основе гидродинамической модели участка реки Чарыш произведен расчет прямой и обратной задачи определения полного массового расхода консервативного загрязнителя при различных сценариях диффузного загрязнения. Расчет обратной задачи выполнен с использованием методов нелинейной глобальной оптимизации и Монте-Карло на основе полиномиального представления распределения полного массового расхода. Установлено удовлетворительное согласие восстановленных и исходных распределений, при этом получена оценка эффективной величины числа Пекле. Выяснено, что значение эффективной величины числа Пекле находится в интервале его реального изменения.

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.
