Dam Floods, Failures and Disasters in 2022

This annual overview highlights the dam induced flood disasters, dam failure incidents in India during 2022. This year, the massive floods in Godavari have exposed the flood vulnerability of giant projects like Polavaram and Kaleshwaram. Also there have been multiple dam failures and dam induced floods in Madhya Pradesh, Tamil Nadu and Kerala. In absence of coordination and data sharing Hirakud induced floods in Mahanadi basin have affected several villages in Odisha and Chhattisgarh. There have been several instances of unscientific operations of dams and the operators continue to hide behind TINA (There Is No Alternative) excuse.
