SUMMARY:

Rio das Velhas, located in the state of Minas Gerais, has water quality parameters that do not comply with environmental legislation. Thus, an efficient management of water resources is necessary in order to guarantee water quality. In this context, water quality models can be used as an alternative to assist in planning and decision-making by managers. Among the various models, QUAL2Kw presents itself as an efficient tool in water quality simulation. In this sense, this research aims to simulate the water quality of Rio das Velhas through the QUAL2Kw model, seeking to support the planning of the basin, in terms of interventions aimed at improving water quality. For this, 185 km of length of the Rio das Velhas were simulated, from the city of Raposos to Jaboticatubas, simulating the parameters OD and BOD. First, this model was calibrated and validated. In addition, in order to facilitate the accounting of polluting loads in the Rio das Velhas, the Ribeirão Arrudas was also simulated, from its source to its mouth in the Rio das Velhas and this to the city of Jaboticatubas, totaling a stretch of 195 km. This new model was also calibrated and validated. Scenarios were simulated to evaluate alternatives for improving the water quality of Rio das Velhas. These scenarios proposed a reduction in the discharge of raw sewage in the main sub-basins of Ribeirão Arrudas and Ribeirão Onça and an improvement in the efficiency of BOD removal from ETE Onça. It was found that the 80% reduction in the discharge of untreated sewage in the Jatobá sub-basin of Ribeirão Arrudas together with the 9% improvement in the BOD removal efficiency of the Onça ETE provide a significant improvement in water quality. of the Rio das Velhas. This scenario manages to reach the limits established by the legislation for the OD and BOD parameters about 16 km before the current situation. In this sense, it is concluded that the model proved to be able to assist in the planning of the basin, aimed at improving the water quality of Rio das Velhas.
