Highest Flood Level (HFL) breach incidents are important indicator of flood cycle and could also help in understanding the changing rainfall pattern. Though, with 925 mm rainfall [i], the south west monsoon season 2022 falls in normal category, its distribution both temporally and spatially has seen huge variations. This is also reflected by at least 57 HFL breach incidents in 8 river basin across the country during the SW Monsoon months of July-Sept 2022.

For past four years, SANDRP has been tracking the HFL breach incidents during pre-monsoon and monsoon months. The analysis of such HFL breaches in 2018 [ii], 2019 [iii] and 2020 [iv], May-Sept 2021 [v], Oct.-Nov 2021 [vi] can be seen on our website. The pre-monsoon months of May and June 2022 [vii] have also seen 5 HFL breach incidents. This report tracks the other HFL breach incidents taking place between July and September months.

DRP 190922: Dams bringing unprecedented changes to the World’s Rivers

September 19, 2022February 23, 2026 SANDRP2 Comments

A new study published this week once again highlights not so well known impact of large dams on the rivers: role of rivers in building, supplying sediment, nutrients to floodplains, deltas, coastlines, estuaries, oceans and supporting so much biodiversity and how large dams are majorly adversely impacting this role of rivers. The study by scientists at Dartmouth using images from the NASA-US Geological Survey for 414 of the world’s largest rivers show the unprecedented changes the dams are bringing to World’s rivers, the impacts that in many cases are outweighing the impacts of climate change. This is particularly true of the northern hemisphere that includes India, World’s third largest dam builder.

Unfortunately in India, there is very little appreciation or acknowledgement of this role of rivers and how dams are affecting it. The least one can expect is that the Government of India should urgently initiate a study to document and understand this phenomena and also highlight what needs to be done about it. The study should be done by an independent team of multidisciplinary experts.

DRP 120922: Decisive judicial action dire necessity for wetlands

September 12, 2022February 23, 2026 SANDRPLeave a comment

( Feature Image:- Satish Acharya’s illustration on Bengaluru floods: Whose land is it anyway? 07 Sept. 2022)

The wetlands reports tell us a lot, but the key point is that decisive judicial action is necessary if our wetlands are to have any future. The directions of the Tamil Nadu High Court to geo reference all wetlands of Tamil Nadu, including small (Less than 2.25 ha area) is good beginning, but the court will need to ensure continuous monitoring and ensure implementation. Because the past shows that the government and other stakeholders have collectively failed to take any decisive action to save our wetlands. The disastrous results are evident at so many places, this week it is most clear from the flooding of Bangalore, mainly due to encroachment of lakes, wetlands, water channels and their catchments.

DRP 050922: Corruption in Large Dams & pro dam media Mughals

September 5, 2022February 23, 2026 SANDRP2 Comments

As this article on corruption in large dams in India shows, it is open secret that large dams involve massive corruption, kickbacks and political funding. But the politicians from PM downwards across the party lines have understandably no interest in this issue.

But unfortunately, the large dams-corruption is not limited to politicians. The corruption in various forms plague even the media Mughals like Swaminathan Ankalesaria Aiyer and Shekhar Gupta, both known for their fundamentalist pro dam views. They too have no interest in corruption in large dams. In fact some of them have no qualms accepting sponsorships of dam contractors for their media awards! They are however, ever ready to criticize Narmada Bachao Andolan and Medha Patkar, though they have no clue about the issues they are talking about and keep using some flawed study whose reply (by Nandini Oza and Shripad Dharmadhikary) is already out in public domain. It is interesting that they have launched this fresh attack on dam critics just when Gujarat Chief Minister and country’s Home Minister have also launched attack on the NBA. Neither Gujarat CM, PM or HM is replying as to why Kutch, the main justification for Gujarat getting disproportionate share of Narmada waters, were the last to get their share of the water (even now not fully as the canal distribution system is still incomplete), almost two decades after the water rich Central Gujarat started getting Narmada waters. Nor are the pro dam media Mughals bothered about this.

Monsoon 2022: CWC Changing HFLs in Ad-hock Manner

During monsoon season, Centre Water Commission’s (CWC) carries flood monitoring and forecast work through a network of 332 stations [i] covering 20 major river basins. The stations are comprised of Level Forecast (LF), Level Monitoring (LM) and Inflow Forecast (IF) sites. The LF sites have Warning Level (WL), Danger Level (DL), Highest Flood Level (HFL), date of HFL information while LM sites maintain HFL and HFL date records. At IF sites flood level for respective dams/ barrages with inflow, out flow figures are measured and forecast is issued accordingly.

However, there are plenty of concerns plaguing CWC’s flood forecast and monitoring work across country for years. In this 2022 SW monsoon season, the agency has exhibited one more problematic tendency which exhibits not only its careless approach vis-a-vis keeping accurate information of HFL breach events, but it also seems strange that it realises it has giving wrong HFL level and date information mostly only after crossing the HFL now.

DRP 290822: MP’s Dam safety mess: Publish the Karam inquiry report

(Feature Image: Karam dam after breach. Source: Patrika)

Every week we get more evidence of the massive Dam safety mess in Madhya Pradesh. The Karam dam disaster that started on the eve of independence day is still unfolding. The inquiry committee report has been submitted, but it has not been made public. This is totally wrong and shocking. Dam Safety is a public interest issue and all information related to dam safety has to be in public domain. The inquiry committee report should be immediately put in public domain. More importantly an independent inquiry should be set up as the inquiry set up earlier was more of an in-house inquiry.

Close on heals of Karam dam disaster comes the news of risks due to unattended Maheshwar dam, a massive dam on Narmada river that remains unfinished and unattended, with one of the gates damaged and story of stolen motors, wires and other spare parts and power cut, which means the hydraulic system for gates is non-functional. Again the report of the NVDA-MWR officials after visit to the dam site should be in out in public domain, as also the reports of the dam safety committee reportedly set up the MP govt for assessing safety of all the dams of MP.

A much awaited flood spell has flowed through Delhi during August 13-14, 2022. It came after more than two months of south west monsoon. Usually by this time, Yamuna river would have witnessed two or three flood spells in national capital lending a fresh lease of life to one of the most polluted rivers of India.

The small scale flood spell in the river has invaded parts of floodplains under abuse and encroachment by government agencies in open defiance of National Green Tribunal (NGT) January 13, 2015 judgement [i]. Apart from this flood, Delhi stretch of the river has witnessed few more abnormal events in this monsoon season so far.

DRP 01 Aug 2022: Dams reduce sediment load in rivers leading to higher coastal erosion

August 1, 2022February 23, 2026 SANDRP1 Comment

A new study this week has reminded us what has been known for long. Dams not only store water but also trap the sediment flowing in the river. Whatever smaller quantity of water flow from dams to downstream areas, has much lower or no silt. A lot of that silt was supposed to reach the coast, helping fight against the erosion of the coast due to sea tides and waves. With drastically lower sediment reaching the coasts, higher coastal erosion is the result. While climate change is definitely contributing to the increased coast erosion due to more frequent and higher intensity storms from the sea, the role of dams tend to work as force multiplier in increasing the coastal erosion due to less sediment reaching the coasts from river.

While a new study by a Pune University has highlighted this phenomena in case of Godavari river, peninsular India’s biggest river, this is also happening at most other rivers and where they meet the coasts. As in case of Farakka, closer the terminal dam is to the coast, greater is its effectiveness to trap the river sediment and higher is its contribution likely to be to the increase in coastal erosion.
