MODELING OF THE PROCESSES OF DISTRIBUTION OF POLLUTANTS IN WATER-COURSES AND RIVERS
The article is devoted to simulation of convective-diffusion transport and transformation of substances (CDT and TS) in rivers and streams. The general formula of the CDT and TS was given. After that it was simplified and supplemented for modeling purposes. It was decided to use the method of finite differences to make solution on a computer. To implement the numerical method of solving the problem, the formula again suffered a number of changes and got the final form.
