In this third annual overview on dams and hydro power projects, we have compiled the reports on flood disasters caused by unscientific or improper operation of dams, hydro and barrage projects in India in 2023. The report highlights criminal negligence by SSNNL and BBMP resulting in massive flood destruction in parts of Himachal Pradesh, Punjab, Gujarat and Madhya Pradesh.

Similarly, the sudden discharges from hydro power dams in Assam, Himachal and Uttarakhand have caused flash flood deluge damaging human properties along the respective rivers. The report also covers some incidents of barrage induced flood events along Ganga in Uttar Pradesh and along Yamuna in Delhi. The first part of the series on Hydro and dam related accidents and second part on People’s Protests against Hydro & Dam Projects in India in 2023 can be seen here and here respectively.

DRP NB 181223: Varanasi’s illegal tent city inaugurated by Prime Minister in Jan 2023

(Feature Image: Collage of Sentinel Hub satellite images of Tent City location in Ganga river bed in Varanasi from Nov. 26, 2022 to Dec. 11, 2023)

While the NGT putting a stay on the Varanasi Tent city and imposing a fine of Rs 25000 on MoEF for not responding to NGT about how the turtle sanctuary was denotified is welcome, we hope NGT takes it to its logical conclusion. It is strange, to say the least to see the NMCG telling NGT through its one page report dated Dec 13 2023 that the Varanasi Development Authority proposal dated Nov 28 2023 for tent city is under consideration! The Tent city companies were fined by NGT, but UP PCB is yet to do anything to collect the fine. Most interestingly, the Prime Minister, no less, inaugurated the tent city project on January 13 2023, over 11 months back! And very shockingly, none of the National Media is even reporting this remarkable situation.

SANDRP has compiled Highest Flood Level (HFL) breach incidents, which includes 2 incidents in June, 34 in July, 17 in August, 22 in September 2023. This report presents the final summary of all HFL breach incidents taking place during South West Monsoon season 2023. The PDF file has the details on all the HFL breach. Our previous reports on the subject can be seen here: HFL breach incidents in 2018, 2019, 2020, May-Sept 2021, Oct.-Nov 2021, May-June 2022 and July-October 2022. .

Several of Narmada basin districts in Madhya Pradesh have witnessed heavy to very heavy rainfall spells between September 14 to 16, 2023 resulting in severe flood situation along the river in Madhya Pradesh and Gujarat and resultantly leading to breaching of Highest Flood Level (HFL) at 13 sites in Narmada Basin alone. Similarly, there have been at least 5 more HFL breaches during the same period in western India.

A floodplain, according to the US Federal Emergency Management Agency, is “any land area susceptible to being inundated by floodwaters from any source”. According to the report “Human alterations of the global floodplains 1992–2019”, over 460,000 sqkms of floodplain area was lost to agriculture, while another 140,000 sqkms was redeveloped to new areas over the existing floodplain. Continent-wise, Asia lost the biggest area of floodplains — a little over 200,000 sqkms — among all the continents. It was followed by South America (92,000 sqkms) and Africa (73,000 sqkms).

Unaccountable Sardar Sarovar operators again bring avoidable floods in downstream Gujarat

September 17, 2023September 21, 2023 SANDRP1 Comment

Late, lethargic and unaccountable actions of Sardar Sarovar Project (SSP) Dam operators have once again contributed to huge and largely avoidable downstream floods in Gujarat. The water level at Golden Bridge in Bharuch is approaching HFL (Highest Flood Level) today on Sept 17, 2023, but these floods could have been significantly lower and much less disastrous both for SSP upstream and downstream areas if SSP authorities had taken action earlier based on actionable information available and based on sound reservoir operation principles of following a rule curve.

Though August 2023 has turned out to be hottest and driest month in a century; the first half the month has seen extreme flood events happening in North, North East and Central zones of the country causing breach in the highest flood level (HFL) at least at 17 flood monitoring sites being managed by Central Water Commission (CWC). These sites are in Ganga, Narmada and Brahmaputra basins.

There are some sites where HFL has been breached in June and July 2023 also and peak flood level of these sites is given below the peak levels attained in August 2023. The details of 2 sites breaching HFLs in June 2023 & 38 sites in July 2023 can be seen by clicking on respective hyperlinks. A separate report analyzing the severe flood situation in Alaknanda and Ganga basin on August 14, 2023 can be seen here.

DRP NB 04092023: Will National Ganga Mission too fail to clean up Ganga?

September 4, 2023September 4, 2023 SANDRPLeave a comment

(Feature Image: Untreated industrial effluents being dumped in Drain No. 6, Sonipat in May 2023.)

More than 7 years have passed since the central government launched Rs. 20, 000 crores Namami Gange Programme in May 2015 replacing Ganga Action Plan (GAP) and created National Mission for Clean Ganga (NMCG) a nodal agency to implement the programme.

The NMCG has already missed the target of cleaning the Ganga by 2019 and then by 2020 due to improper planning and Detailed Project Reports (DPRs) as accepted by G. Asok Kumar, Director General (DG), NMCG in an interview to The Week in January 2023 further extending the target to 2026.

Though Namami Gange aimed to adopt a basin wise approach with focus on e-flows, afforestation, revival of tributaries, biodiversity conservation in participatory manner; so far it has extensively worked on creation of sewage treatment infrastructures in the states along the main stem of the river.

Despite that the ground situation is far from improving as shown in the The Hindu report below which reveals that about 80 percent of the overall budget is being spent on sewage infrastructure creation and by 2026, the treatment plants capacity would be able to treat at the most 60 percent of sewage generated only along the main stem of the Ganga river.

DRP NB 260623: National Framework for Sediment Management

June 26, 2023June 26, 2023 SANDRPLeave a comment

A National Framework for Sediment Management is certainly a long standing requirement and any move in that direction would have been welcome. Not only because the sediment accumulation destroys storage capacity of India’s Dams, created at such massive costs. But also because sediment is an integral part of river flow and also very important for the rivers to stop or reduce erosion at deltas. There are other issues related to sediment including creation and disposal of toxic sediment and impact of sediment free water flowing downstream from the hydropower projects.

But we need much more serious and sincere efforts in this direction than what has been suggested in following government press release. The movement on such an important subject is so snail paced, half hearted, non-comprehensive, unscientific and non-sincere that it is not clear how this is going to help.
