Why is Dam Safety a priority concern in India?
- Third-Highest Number of Dams Globally: India has over 4,407 large dams, following China and the USA.
- Aging Dams: By 2025, over 1,115 dams will be more than 50 years old; By 2050, 4,250 dams will surpass 50 years of age, with 64 dams exceeding 150 years.
- Decreasing Storage Capacity: Sedimentation reduces reservoir efficiency, affecting water availability for irrigation, drinking, and hydropower. Ex. Bhakra Dam has experienced 139.86% higher siltation rates than estimated, reducing its lifespan.
- Structural Vulnerabilities: Poorly designed sedimentation management systems make many dams structurally weak over time. Extreme environmental events, such as floods, can exacerbate these vulnerabilities.
- Lack of Data and Monitoring: Insufficient documentation of storage loss, sedimentation rates, and other critical metrics leads to a lack of preparedness.
