SUMMARY:

This study investigated the water quality of the Alagado stream (DF/GO) through the analysis of water quality parameters, the application of the classification compliance index, and hydrological and water quality modeling using the SWAT+ model. Additionally, three different landscape units were analyzed to understand their unique characteristics and their impact on the results for the delineation of LSUs, flow, and water quality. The results revealed that certain parameters, such as phosphorus and coliforms, exceeded regulatory limits, indicating a concern with pollution. The SWAT+ model for water quality did not achieve satisfactory calibration. However, despite the limitations, it provided valuable insights, such as the distribution of nutrient contributions, like phosphorus and nitrogen, from surface runoff, as well as data on the basin's evapotranspiration. These results are crucial for understanding the hydrological processes and pollution sources in the studied area. Furthermore, the analysis of different landscape units revealed significant disparities. The DEM Inversion method unit proved to be closer to reality when compared to slope factors, elevation, and the LS factor, suggesting a more realistic representation of the environment. This study is particularly relevant because the Alagado stream is one of the main tributaries of the Corumbá IV system, in the segment of the reservoir where surface water is captured to supply the Federal District and municipalities in the state of Goiás. Therefore, the results of this work aim to contribute to the management and conservation of this transboundary water body, highlighting the importance of pollution control measures and sustainable management strategies to ensure the region's water security.
