Retention basins have become increasingly important in both Brazil and the USA as urban areas expand and climate change intensifies rainfall patterns. In Brazil, particularly in cities like São Paulo and Rio de Janeiro, retention basins are critical infrastructure for preventing the devastating floods that occur during rainy seasons. In the USA, they are standard components of modern urban development and stormwater management plans, often incorporated into parks and recreational areas for dual purposes.
