DRP NB 16 March 2020: Invitation to another Kedarnath floods tragedy?

This remarkable TOI report on March 14, 2020 (there was a Hindustan Times Report on March 9, 2020, we found out later: https://www.hindustantimes.com/india-news/scientist-flags-kedarnath-project-worries/story-1DoLBHLeMOmYLI3OPFOq1M.html) says that rampant redevelopments termed as “unabated unscientific work in the valley” around Kedarnath is likely to create dangerous situation leading to 2013 like catastrophe. We could not find report about such an important development in any other media.

But this detailed report, not contradicted by any of the quoted sources, seems sufficient reason to be alarmed by all concerned.

Experts of the Wildlife Institute of India, Wadia Institute of Himalayan Geology, Uttarakhand Space Application Centre (USAC) and even the Principle Science advisor to the Prime Minister K VIjay Raghavan and also the contractors, Woodstone Constructions along with other state and central govt officials were present where officials made some candid presentations. It seems there has been neither any impact assessment studies or clearances for the controversial interventions happening, including 9 km long approach road for Kedarnath on the left bank of Mandakini river, (left band has basically loose glacial sediments and hence is unstable and could get affected by avalanches and landslides) and a massive 50 ft deep and 100 m wide pit just 50 m behind Kedarnath for the Samadhi sthal. MPS Bisht, the Director of USAC in his presentation called the pit an extremely dangerous for future. He asked: “Why are we creating a situation for another disaster like the 2013 tragedy to take place again?” Scientists from the Wadia Institute are quoted saying: “The Road being built to Kedarnath is being made on the most vulnerable of Kedarnath Valley and may any day collapse under the pressure of so many glacier shoots which are directly opening on the road.” Raghavan called these revelations tipping points.

CWC - Central Water Commission

South India Overview of CWC Flood Forecasting Sites 2019

Flood Forecasting (FF) is one of the important activities of Central Water Commission (CWC), which is undergoing expansion and improvement, but there is still a huge scope for improvement. In order to better understand the CWC’s flood monitoring and forecasting work, in this article, we have given an overview of CWC’s flood forecasting and monitoring sites in South India, the last region to be covered for 2019 flood season. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in South Indian states of Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Puducherry (no FF sites) and Kerala. Similar report has been published for North India[i] and North East India[ii], East India[iii] and West India[iv].    Continue reading “South India Overview of CWC Flood Forecasting Sites 2019”

Dams Floods 2018: Filling up Dams well before Monsoon end, Invitation to Disaster

The tendency of filling up reservoirs in the beginning and middle of monsoon season have been leading to avoidable flood disasters in the country. Apart from Kerala flood 2018, which was aggravated by mismanagement of reservoirs, various reports show that reservoirs in river basin of Cauvery, Krishna, Godavari and Ganga were also filled up well before the end of South West monsoon season. Resultantly there were many man made flood spells in downstream areas affecting lives and livelihoods of people.

After highlighting role of dams in floods in Kerala and how improper dam operation affected people in Assam and Himachal Pradesh, this third and concluding part throws light on other dam induced flood (and canal breach) incidents in 2018.

Cauvery is facing very serious flood risk, but CWC is in slumber

(The figure above is screen shot of CWC Flood forecasting site showing no warning signs even at 5 pm on 230718)

Almost all the big dams in Cauvery Basin are full on the earlier ever monsoon date this year. This includes Krishnaraj Sagar, Mettur, Kabini, Harangi, Hemavathi and Bhavanisagar. They are almost full and have started releasing large flows to the downstream areas. This is when we are past just about six weeks of South West Monsoon, the North East monsoon would come after that. It means that the basin is facing major risk of floods in next 2-5 months. And yet Central Water Commission, India’s flood forecasting agency, seems to be in deep slumber. It has not even bothered to update the flood readings on its designated sites from the 2017 figures.  Continue reading “Cauvery is facing very serious flood risk, but CWC is in slumber”

Cauvery · Inter State Water Disputes

Cauvery: Is there will for way forward? Will constitution of CMB help?

Above Map of Cauvery basin from Indian Express, Sept 22, 2016

Higher demands than availability is the key problem in Cauvery basin. transparent, participatory, democratic, rule based management of demands over supply is the key need. Unfortunately, we do not have that. Greater misfortune is that the Cauvery Water Disputes Tribunal Award of Feb 2007, even as it is significantly flawed, is yet to be implemented since the Special Leave Petitions of Karnataka and Tamil Nadu, admitted in the Supreme Court, remain pending for over nine years now. The Supreme Court, in the meantime, (through its orders of Sept 5, 12 and 20) deals with the issue in a manner, that seems ad hoc in absence of clarity as to how all the relevant factors have been taken into account.  Continue reading “Cauvery: Is there will for way forward?
