One of the heartening development this week is from Kerala, where Chalakudy river community held a satyagraha to demand proper integrated dam management plan in the Chalakudy River basin to minimize flood risks. It is rather rare that communities come out for such a demand. It was also great to see that the satyagraha was supported by Chalakudy Puzha Samrakshan Samiti, Chalakudy municipal chairman and also environmentalists.

The satyagraha in fact had specific demand for each of the dams included in the Paramibikulam Aliyar Project, including in Kerala and upstream Tamil Nadu. We hope the Kerala government positively responds to these demands at the earliest.

In the past one month there have been some interesting judicial interventions taking up the matters of floodplain, pollution and aquatic eco-system of the Yamuna River in Uttar Pradesh, Delhi, Haryana and Himachal Pradesh. Of these, the most significant one is the NGT order on July 11 fining MoJS & CWC of ₹50 000 each for the non-demarcation of floodplain in Agra.

The fine was to be submitted before Aug. 06,2024 hearing but there is no update available so far on this. It is also not clear whether Yamuna floodplain has been demarcated and officially notified in Agra stretch or not. Earlier in May 2019 and March 2022, the NGT had asked for demarcation of Yamuna floodplain in Agra and Mathura respectively.

It is rather rare when we find anything in media about celebrating our monsoons. We find this week more than one piece about such celebration in various ways including through creating works like Bollywood songs and poetry in various languages of India.

In a detailed article famous Bollywood related author Jerry Pinto writes about the fascinating Bollywood songs related to monsoon and their picturization. He writes that the great tradition seems to be fading out, but hopefully that will not be the case. Incidentally the article should have mentioned the name of one of the best lyricist, author and film maker, Gulzar, who has shown more love for monsoon that possibly anyone else in Bollywood.

The news this week that SSNNL has decided to operate the 1200 MW River Bed Power House and the 250 MW Canal Head Power house to reduce the water level in Dam from 122.28 meters on June 14 to around 115 m before the monsoon inflows start, in anticipation of the above average rainfall anticipated during SW Monsoon 2024 is welcome. One hopes this is sign of SSNNL, Gujarat Government and the Narmada Control Authority have learnt some lessons after the avoidable flood disasters brought by SSP in 2023 and earlier in 2019 and 2020, as revealed by SANDRP’s analysis in each of these years.

One hopes this is not just one-off ad-hoc decisions, but part of a systemic change. This will require an integrated basin level reservoir operation policy including all the major dams of the Narmada Valley and put it out in public domain along with clearly defined Standard Operating Procedure, and names of the responsible officials for each of such major dam in the basin. The Central Water Commission will also need to be held accountable for its flood forecasting including the 7-day advance forecasts.

DRP NB 100624: Global research suggests: shun big dams, big hydro

Two separate reports this week shows why we need to shun big dams, big hydro. The New York Times, based on several research papers have said that unstable water cycles are making big hydropower projects unreliable. This is clear this year from a number of countries, including India, China, Canada, Turkey and Ecuador among others. The report also emphasizes the loss of biodiversity, methane emissions, submergence, among other issues plaguing the hydropower projects.

Another report quoting Stanford University study says that big reservoirs cannot meet future water storage needs and we need to go for alternative, nature-based storage options. Alternative storage options like soil moisture, aquifers and local water systems. Such storage options also provide “the critical synergy between water infrastructure, climate adaptation, and agricultural resilience.”

Both are highly eminently relevant for India. When will we start adopting such options?

The river sand mining stories this week makes fascinating reading. We have stories from Andhra Pradesh, Telangana, Uttar Pradesh, Goa, Rajasthan, Madhya Pradesh and Punjab. The stories from first five states are related to judiciary. One story from Punjab is about collapse of a bridge due to illegal mining and another about how illegal sand mining is part of electoral narrative. The story from Madhya Pradesh is possibly most interesting and most indicative of the direction in which we need to go. In MP at a public hearing for sand mining project, the women of the villages, including sarpanch, have decided to save the river rather than allow unsustainable mining.

The stories from five states about judicial actions includes the one from Andhra Pradesh where the Supreme Court of India has warned the govt about contempt action. The apex court has set up committees of govt officials in Krishna and Guntur districts to stop illegal mechanized sand mining. The story from Rajasthan is about Supreme Court stopping sand mining in 1 km radius around Sariska Tiger Reserve. The stories from next two states is about the NGT action. Lastly, the story from Goa is about High Court action.

DRP NB 200524: After Ten years of Namami Gange and Rs 40 000 Cr expenditure Ganga remains dirty

The reports this week from Ganga basin rivers clearly show that after ten years of Namami Gange and NMCG (National Mission for Clean Ganga) efforts and expenditure of over Rs 40 000 Cr, there is no improvement in even river pollution, leave aside the state of river flows or state of the rivers in the Ganga basin.

In fact, there is nothing to show that even the new STPs are making any difference to the river even with respect to the limited objective of sewage treatment. As highlighted in the report below, until and unless the governance of STPs become more transparent, accountable and participatory, there is no hope for change, no matter how much money is spent, how much new STP capacity is added or what technology is used. Only a responsive, confidence inspiring governance can make a difference. But there is no interest in working in that direction from the government.

As per this Reuters report based on official information and statements, in June 2024 India will face the biggest peak hour power shortfall in 14 years, mainly due to the slump in hydropower generation. This is the result of not only pushing hydropower projects over the decades, but also not taking any steps to optimize peaking power generation from existing hydro or doing anything worthwhile to manage peak load. India’s hydropower generation had steepest fall in four decades in the year ending on March 31 2024, which was another reason not on rely on unreliable hydropower projects. The regular and frequent disasters that we see connected with hydropower projects in almost every month and more frequently in monsoons should be another reason in this regard.

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

May 6, 2024May 7, 2024 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.
