A STUDY TO ENHANCE WATER RESOURCES IN CHINA THROUGH ADVANCED WATER MANAGEMENT UTILISING HYDRODYNAMIC MODELLING.

Abstract

A three-dimensional water quality model was utilised in order to evaluate the short-term water condition forecast of Nam Theun 2 Reservoir. This model was then utilised in order to investigate a number of different scenarios. Every single one of the objectives that were outlined by the model was accomplished. In fifteen years, it is projected that the level of water column oxygen will increase, although certain regions of the reserve will contain hypolimnion that is devoid of oxygen. Eventually, substances that are hazardous to the ecosystem will disappear from the environment. This article presents two examples that highlight the significance of hydrodynamics in the process of water quality development. Both of these examples involve the use of shifting natural or human-induced forces. The period of time that crucial hydro meteorological events such as rainfall, floods, and drops in air temperature continue to occur throughout the year has a significant impact on the quality of the water that is contained within reservoirs. Hydro meteorological data over several years demonstrates how fundamentally distinct the conditions were. All indications point to the truth that the durations of these episodes have an effect on the quality of the water. If the electrical plant had started up directly after the impoundment commenced, the physical characteristics of the water below it would have been various, based on the results of the calculations. With the use of the model, investigators have investigated the consequences of altering land use in the watershed, which led to an increase in the levels of NO₂ and PO₂ in the watershed. A single currency serves as a metaphor for the competition that exists between various approaches to water consumption.
