The short-term water condition forecast for the nam theun 2 reservoir was analysed with the help of a water quality model that was three-dimensional. In the subsequent steps, this model was utilised to investigate a variety of additional potential scenarios. All of the objectives that were set for the model were accomplished. There will still be areas of the reserve that do not have any oxygen in the hypolimnion, despite the fact that it is anticipated that the oxygen content in the water column will increase in fifteen years. In the course of time, potentially harmful compounds will gradually disappear from the environment. The article provides two instances that illustrate how hydrodynamics could potentially contribute to the cleaning of water. Both scenarios involve dynamic forces, which can occur naturally or be created by individuals. Dynamic forces take place in both circumstances. A significant impact on the quality of the water contained in reservoirs is exerted by the duration of significant hydro meteorological phenomena such as precipitation, flooding, and temperature drops. Several years' worth of hydro meteorological data demonstrates how drastically different the weather was during that time period. The durations of these occurrences do, in fact, have an impact on the quality of the water, as indicated by all of the indicators that are available. In accordance with the calculations, the physical features of the water that is located beneath the impoundment would have been different if the power plant had been engaged immediately after the impoundment had been established. The model has been utilised by researchers to investigate the relationship between changes in land use in the watershed and the levels of no₂ and po₂ in the watershed. The fact that there is only one currency demonstrates the competition that exists between the various ways that water can be used.
