We are in the thick of monsoon and also flood season. To manage floods, key inputs are accurate forecasts and prompt, accurate, location, river specific rainfall. India Meteorological department has a key role to play in all these aspects that can help us manage floods, as a very pointed Editorial in Indian Express stated in the context of Assam Chief Minister Himanta Biswa Sarma’s flip flops.

The edit referred to the 2021 parliamentary panel report that asked the Centre to set up modern weather stations in the upstream catchment of the Northeast’s rivers and install sirens to alert people downstream of floods. North East and rest of the country continues to lack such systems.

The sequence of events over the last two decades that ended this week with white paper on Polavaram project being released by the newly elected Andhra Pradesh govt underlines urgent need for an independent assessment of the multi-state Polavaram Project on Godavari River in Andhra Pradesh.

The story of the project similar to, though a bit longer than that of the ill-fated Kaleshwaram Project of the neighbor Telugu speaking state of Telangana. Both are ill-conceived, expensive, high impact projects on same Godavari River, both taken forward without sufficient studies and implemented without sufficient checks and balances.

In the wake of water crisis in Delhi, the Supreme Court on June 3, 2024 has directed Upper Yamuna River Board (UYRB) to convene urgent meeting on June 5, 2024 and submit status report in the court by June 6, 2024. The direction came following Delhi government claim that the state of Himachal Pradesh is ready to share surplus water with it and for that it required cooperation from Haryana government. The outcome would hopefully be known by the evening on June 5 2024.

Given the prevailing political equations among the basin states, there is uncertainty whether the board would be able to effectively resolve the issue. The UYRB suffers from some flaws in formation and functioning. The board is working in an opaque manner. Presently its website is inaccessible and meeting minutes are not in public domain. It is also reportedly crippled by shortage of staff as against originally sanctioned post of 58, it is currently functioning with just 5 officials.

DRP 060524: Study on dam induced river flooding in Peninsular India

May 6, 2024February 28, 2026 SANDRPLeave a comment

(Feature Image: (a) Locations of streamflow gauges with catchment boundaries in six major river basins of Peninsular India, (b) elevation map and mean annual maximum runoff rate (streamflow per unit catchment area), (c) Aridity Index (AI) and (d) Baseflow Index (BFI). The maps in first row are prepared in QGIS (Version 2.14.0 ‘Essen’ (2016), URL: http://qgis.org) and the maps in second row are generated using R (Version 4.2.2 (2022), URL: https://www.R-project.org/). Source: Baseflow significantly contributes to river floods in Peninsular India )

A recently published study, see details given below throws light on the role of groundwater contribution to baseflow in rivers and their flooding in Peninsular India’s river like Narmada, Tapi, Mahanadi, Godavari, Krishna and Cauvery. The found that while baseflow contributes more to river flows, its share in the flood event flow magnitude decreases as surface runoff accounts for a larger proportion of flood discharge on the day of the flood.

Most significant are the findings related to dam induced flood that SANDRP has been writing for long and the finding corroborate exactly what SANDRP has been saying: Sudden releases of water from a dam can raise river levels during extreme rainfall events, especially when the dam is nearly full. The impact of sudden floods is more destructive because people living in nearby areas are often unprepared. Without a dam, floodwaters rise slowly over time, allowing people to take preventive measures. However, sudden floods caused by dam releases offer little or no time to prepare, increasing the risks associated with dam-induced flood hazards. Furthermore, the construction of dams alters the natural regime of rivers, leading to changes in sediment transport and erosion patterns. These changes can heighten the risk of flooding downstream from a dam.

DRP 290424: Why is Climate Change not major election issue?

World’s largest democratic exercise is now ongoing in India to elect the members of India’s Lok Sabha. Over 97 crores are eligible to vote in these elections. One of the biggest factors that is adversely affecting people across India currently is Climate Change. It is affecting almost every aspect of life and the adverse impacts are only increasing with every passing year. This is man-made disaster basically happening due to anthropogenic reasons, affecting air, water, climate, food, health, livelihoods, disasters and so on, affecting everyone. Currently, India is also a major contributor to the climate change causing green-house gas emissions, even though historically, the developed countries have contributed much more.

More importantly, the development options that the elected government choose will decide how the people will be impacted by climate change. The government has large number of options for pathways to development. Considering all this, one expected that climate change responses will be a major issue in these elections. But that is clearly not the case. BJP and Congress, two of the biggest parties fighting the elections, have mentioned climate change in their manifestos, but neither has dealt with this important issue with the detail and seriousness required. Nor are any of them making climate change a major election issue. One expects the ruling party to at least respond in greater detail and seriousness to this issue, but that is not the case.

DRP 220424: International Energy Agency accepts high-cost high risk hydro is no longer High Priority

April 22, 2024February 28, 2026 SANDRPLeave a comment

The International Energy Agency (IEA) has accepted in its latest World Energy Investment Special Report titled “Reducing the Cost of Capital: Strategies to unlock clean energy investment in emerging and developing economies” has candidly accepted that hydropower (excluding pump storage) is no longer the high-priority sector.

Among the challenges hydropower faces, according to IEA, include long permitting time necessary considering the high and complex impacts of hydropower projects amd delays during construction. IEA figures show that the capacity of Chinese developed hydropower projects that had high proportion of installed hydropower capacity globally in any year for decades, was the lowest in 2023 since 2014. The report accepts that high cost of capital with high interest rates can have a major impact on Cost of electricity, affecting competitiveness of the hydropower projects.

The demand of NAPM to political parties going to the National elections in next couple of months to include protection of rivers and communities dependent on rivers in their manifestoes is most appropriate and urgently required.

Some key components of the demand include strengthening of decentralized river governance, role in decision making related to rivers for the fisherfolks, boats people and other river dependent communities. A draft of the People’s River Protection Bill has also been sent to the political parties. The NAPM also opposed indiscriminate construction of dams, hydro projects, embankments, barrages, river front developments, illegal sand mining, dumping of solid and liquid waste in the rivers and also interlinking of projects, all being done in the name of development, with least concern for the rivers. The draft bill also demands removal of unjust encroachments into riverbeds and floodplains. NAPM also demands continued flow in the perennial rivers by way of adequate environment flows throughout the length of the rivers from origin to its confluence with other rivers or sea.

Large parts of South India, including Maharashtra are facing depleted reservoir levels with the beginning of summer and water scarcity. However, the Krishna Bheema basin, the second largest basin of peninsular India, is diverting water to outside the basin to Konkan. The Krishna Bheema basin has the largest live storages of Maharashtra in Koyna dam (1347.5 MCM) and Tata dams (617.67 MCM), but the water in those storages won’t be available to the drought hit residents of Krishna basin in water scarce Maharashtra, Karnataka, Telangana and Andhra Pradesh.

This is because Koyna and Tata dams divert the water from Krishna Bheema basins to Konkan for power generation. Even in March, according to Maharashtra Load Dispatch Centre, Koyna had generated 128.87 Million Units (MU) of power and Tata Dams had generated 130.47 MU, both by March 30. This implies diversion of millions of Cubic meters of water from Koyna and Tata Dams during March 2024, which mostly gone down from Konkan to Arabian sea.

The Electoral bonds details now in public domain, thanks to the Supreme Court of India orders, has once again highlighted the political economy of large dams, hydropower projects and irrigation projects. It has once again confirmed what was publicly known that such large water projects involve kickbacks to political parties.

The details so far available involves companies like Megha Engineering, Rithwick Projects Pvt Ltd, Navayuga Engineering Company Ltd, among others. The projects so far that seems to be involved include Polavaram Dam, Kaleshwaram Lift Irrigation Project, Sunni Dam and Hydro projects, Kundah Pump Storage Hydropower project in Tamil Nadu and Silkyara Tunnel, almost all of them also involved in some kind of disaster or other.
