“…The future outlook for the region downstream of the Tucuruí dam tends towards a scenario where the alterations in the dynamics of the flooding and runoff tide of the river will aggravate. In recent years, Brazil has faced successive water crises, where the shortage of rainfall in the South and Southeast regions has reduced the reservoir levels of the main hydroelectric plants in these regions [ 23 ]. We can report that the main factors related to this increase in rainfall deficit are the increase in deforestation in Brazil, especially in the Amazon region, and global climate change [ 24 , 25 ].…”

“…The regulation of the Araguaia River flow will significantly increase the hydropower generation at the Tucuruí Dam and increase the viability of the existing dam potential [29]. This is particularly interesting because Brazil has been suffering from an energy crisis since 2014 [30][31][32]. Another issue in the Araguaia basin is the lack of river flow regulation, which results in a significant loss in hydropower potential in the Tucuruí hydroelectric power plant in the Tocantins River.…”

Groundwater storage is an important water management solution that is overlooked by several countries worldwide. This paper evaluates the potential for storing water in the Bananal sedimentary basin and proposes the construction of canals to reduce sediment obstructions in the river flow and harmful flood events. This would allow for better control of the water level. The water stored in the sedimentary basin can be used as a climate change adaptation measure to ensure that the level of the flood plain is maintained high during a drought or low during an intense flood event. Additionally, the flood plain will function as a water reservoir, regulate the river flow downstream from the flood plain, and enhance hydropower generation. A significantly smaller reservoir area is expected to store water, as the water will be stored as groundwater in the sedimentary basin. Results show that the Bananal basin has the potential to store up to 49 km3 of water, which can add up to 11.7 TWh of energy storage to the Brazilian energy matrix for a CAPEX energy storage cost of 0.095 USD/kWh. This is an interesting solution for the Araguaia basin and several other basins worldwide.
