| Popis: |
Water quality modelling in small rivers is often considered unworthy from a practical and economic point of view. This work shows that a simple model structure can be set up to describe the stationary water quality in small river basins in terms of carbon and nitrogen compounds, when it is unfeasible to use complex models. The one-dimensional model include principle factors such as chemical and biological oxidation, concentration of nutrients. Natural process of self-purification for small river in sharp continental climate of Central Siberia is inhibited by low temperatures, rapid currents and poor development of plankton cenosis. So, a determination of model parameters demands carrying out of special experiments with water samples. The results of numerical modelling are verified by data from the environmental monitoring of some rivers in the basin of Central Enisey. |
