Monitoring tailings remobilization after the VALE S.A. Dam failure in Brumadinho: Impacts of extreme floods assessed through remote sensing

Key Points

• Tailings remobilization significantly increased in the wake of extreme floods.
• Remote sensing identified over 30% changes in tailings distribution post-flooding.
• Observational analysis after the VALE S.A. dam failure utilized satellite imagery and spatial data.
• Highlights the critical need for effective monitoring systems for future dam safety and flood management.
