Argentina began its first large-scale survey of the Bermejo River Basin on 29 March 1936. The study aimed to understand erosion, flooding, and sediment buildup along the river. Engineers and hydrologists traveled through northern provinces to gather data. Their findings highlighted the need for infrastructure improvements. The project supported early discussions about dams, levees, and long-term river management. The survey became essential for reducing flood risks in vulnerable communities. Its launch marked a milestone in national water planning.
