2025 Western Himalayan Floods: What can be done to reduce disastrous impacts?
Scary visuals and messages on social media as also some of the pronouncements of the Supreme Court about Himachal Pradesh have shown that Western. Himalayan states have faced multiple flood disasters in the ongoing SW Monsoon 2025. Landscape of Himalayas is known to be vulnerable to landslides, mudslips, cloudbursts, flash-floods, GLOFs, erosion, seismicity and floods. While some floods are inevitable in the kind of climate prevailing here, how they become disasters is linked to the way we have treated the landscape, environment, regulations, people and floods.

DRP 250825: Threat of Dam Floods continue to be ignored
(Feature Image: The release of water from Pong Dam has brought devastation to Mand Bhograwan village in Kangra district, where the sudden rise in the Beas river has submerged several acres of fertile land and put houses at risk. Aug 17.)
Sudden release of large quantity of water from the dams has the potential of creating avoidable floods in the downstream areas as we could see last week in case of Ukai Dam water releases affecting Surat in South Gujarat, Ujani and Jayakwadi dam water releases in Maharashtra, Bhakra and Pong dam releases in Punjab and Himachal Pradesh, among others. In all these cases, we can show that earlier water release was warranted based on available information, considering the carrying capacity of the downstream river, but such action was delayed till either the dam was full before water started (e.g. Ujani and Jayakwadi) or too large water releases created avoidable flood impacts in case of Ukai Dam on Tapi River in South Gujarat and also in case of Bhakra and Pong dams. There were also extensive damages in Mirzapur and Chandauli districts of Uttar Pradesh due to sudden release of water from a number of dams including Chandra Prabha Dam, Ahraura dam and Jargo Dam among others.

DRP 18 Aug2025: Sustainable Hydropower an Oxymoron?
Analyzing a recent paper authored by 37 persons mainly from academics and hydropower related companies on “Sustainable Hydropower”, Eugene Simonov shows why the phrase is an oxymoron, a contradiction in terms. The paper fails to even refer to the most important work on hydropower projects, the report of the World Commission on Dams.
