Amid concerns over safety and construction quality, the Polavaram project work has moved during 2025 to achieve Dec. 2027 completion target. However, not much progress has been made regarding the backwater study and addressing the issues of affected tribals and areas in Telangana, Odisha and Chhattisgarh. Meanwhile, after failing to push PBLP (Polavaram Banakacherla Link Project), the Andhra govt has proposed another contentious PNLP to divert Godavari River waters. The Stop Work order issued by the MoEF in 2011 remains suspended for all these years, making a mockery of the MoEF regulations. Wrapping up the available information, this overview shares the year-round updates on safety, progress, backwater study and linking plans related to the controversial Polavaram dam project in 2025. Our previous overview on the project can be seen here.

The Day Salun Village Fell: Impacts of Cascading Hydropower Projects in the Ravi Basin

December 8, 2025December 8, 2025 SANDRPLeave a comment

Salun village, perched roughly 50 feet above the Ravi River, had its moment of fame on the 26th August 2025 — a moment that also became its last. On the dark, rainy afternoon, the small village with homes, rajma fields, apple orchards and cattle sheds collapsed into the flooded River Ravi like a house of cards. In a matter of 30 minutes, ancestral homes with warm hearths, blankets for the coming winter, old report cards and wedding albums, adhar cards and bankbooks-entire archives of living-were erased. Villagers, who managed to escape in time stood in awe and saw their village going extinct before their eyes.

Having covered dam induced flood incidents and embankment breach flooding events in part 1 and part 2, this third part on annual overview compiles media reports on manmade Urban flood disasters in India during the year 2024. While the cities of Pune, Nasik, Nagpur, Vadodara and Bharuch were affected by dam induced floods, the high discharges from Prakasam barrage and multiple breaches in Budameru river deluged the Vijayawada city. Interestingly, these urban flood episodes coincided with heavy rainfall events giving a reality check to dam and city managers.

In addition to failure in dam management, the deluge in Pune, Vadodara and Vijayawada city were particularly worsened by river front development projects and encroachment on river floodplains putting question marks on the urban planning and development works in these cities. Similarly, the breach in embankment of Munak canal in Delhi flooded several homes Bawana area during the monsoon season.
