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.

DRP NB 110923: Another independent institution-CEC destroyed

The Govt of India’s Sept 5 2023 notification reconstituting the Central Empowered Committee completely destroys the independent nature of this institution of accountability and course correction. This institution, set up by the Supreme Court in 2002 and reconstituted in 2008, worked as eyes and ears of the Supreme Court on environmental issues. The new committee has no independent members, it will be constituted by the MoEF, MoEF itself has such an abysmally poor track record.

The notification, reports said, diluted the CEC’s autonomy on four key counts: the committee will report to the ministry, instead of the SC; the ministry will pick all the members and the SC will have no role in the process; the ministry, and not the court, will fund the committee; the provision of having two NGOs in the committee has been done away with.

On August 14, 2023, there was flash flood in Alaknanda rivers in Uttarakhand causing sharp rise in water level at Center Water Commission (CWC) stations along Alaknanda upto Devprayag and then along Ganga in Rishikesh and Haridwar. The volume of water was so huge that it narrowly missed breaching the June 2013 peak flood level at Rishikesh and Haridwar site. This report tries to analyze hydrographs of 15 CWC flood monitoring sites on Alaknanda and Ganga rivers to assess the actual flood levels in these rivers during this flood spell in comparison with the previous peak flood levels attained on these sites.

The official report of what has transpired in Sainj Valley under Banjar subdivision of Kullu district during July 8-10, 2023 is still not in public domain, however the multiple media reports suggest it to be one of the worst flood disasters for the valley and have once again raised serious questions on the role the hydroelectric power (HEP) projects. Local people have specifically underlined the gross negligence by National Hydro Power Corporation (NHPC) company for turning floods into a disaster. Moreover, old media reports from the area have also highlighted that it was a disaster in the making for which the state government machinery as well hydro projects and NHPC have contributed hugely.

The analysis of hydrographs being published on Center Water Commission’s (CWC) Flood Forecasting website shows that the previous Highest Flood Levels (HFL) have been breached at least at 34 flood monitoring sites across the country in July 2023. The river basin wise details of all these sites are given in tables below.

The national capital is witnessing one of the worst flood spells with water level at Railway Bridge breaching the highest recorded 207.49 m of Sept 6, 1978 by 1.17 m. The Yamuna seems eager to reclaim all its relict channel and encroached floodplain areas.

The River has set 208.66 meter as new HFL (Highest Flood Levels) for the site at 18:00 hours on 13 July 2023 which is 1.17 meter higher than the 1978’s HFL. The flood level is receding now.

In 2020, south west monsoon season when rainfall was 8.74% above normal, rivers reached new Highest Flood Levels (HFLs) at least at 37 locations across the country, as per information available to SANDRP. Maximum 13 such instances come from Central and East India, each. Five instances happened in South India, three in North India and two in North East India. This article provides wise details and hydrographs of all these sites.

SANDRP has been tracking the Highest Flood Level (HFL) breach incidents during monsoon season. The analysis of such HFL breaches in 2018 and 2019 are available on our website. In 2018 we had listed 25 such instances though SW Monsoon rainfall was 9.4% below normal. In 2019 we listed 37 such instances when the SW Monsoon rainfall was 10% above normal.

How India Measures Water Storages

July 13, 2018July 13, 2018 SANDRP1 Comment

Govt and media typically report the status of water storage in India using the CWC’s Weekly Reservoir Storage Bulletin, which contain information about just 91 reservoirs in India. In this article we show that the state websites provide information about huge 3863 reservoirs, which even if not sufficient, is a huge improvement over just 91 reservoirs that CWC bulletin includes. We hope all concerned will try to improve the reservoir storage reporting.

It should be added here that this measures only surface water stored in some of the large reservoirs of India. This excludes large number of big reservoirs, lakhs of smaller reservoirs, groundwater aquifers and soil moisture storage. In spite of these limitations, this provides more accurate picture than just the 91 reservoirs of CWC that everyone in India, including media, govt monitoring and policy makers look at.

A tale of two National Water reports: NITI and USGS

July 10, 2018July 10, 2018 SANDRPLeave a comment

Within a span of a week, two interesting reports on National Water situation were made public. Indians have heard of NITI Ayog’s first ever report on Composite Water Management Index, trying to put together state of water management in India. Not many here would have heard of the United States Geological Survey (USGS)’s once in five year report on water consumption for various activities and states in USA[i]. The US report was published on June 19, 2018, five days after NITI Ayog report was launched on June 14 by Union Water Resources Minister Nitin Gadkari.[ii] Continue reading “A tale of two National Water reports: NITI and USGS” →

Muddy Siang is sign of danger ahead, wake up call for Indian authorities

December 24, 2017January 2, 2018 SANDRPLeave a comment

The current ongoing episode of Muddy Siang River water in Arunachal Pradesh is due to landslides in the upstream Tibet, triggered by the earthquakes starting on Nov 17, 2017 or possibly earlier. This is revealed by the satellite pictures and work of two researchers, first published in Arunachal Times on Dec 21, 2017[i]. These landslides are partly blocking the Siang flow and could lead to massive floods in the downstream Arunachal Pradesh and Assam any day.

A similar event in year 2000 led to sudden, massive floods in Siang River in Arunachal Pradesh on June 1, 2000. That episode, like the current one, started about 53 days before the floods, on April 9, 2000 due to landslides along a tributary of Yarlung Tsangpo, as Siang is known in Tibet.
