Uttarakhand: Cloud bursts in May 2021

From the beginning of May 2021, Uttarakhand has started witnessing excessive rainfall events termed as ‘cloud bursts’. Worryingly the intensity and frequency seems on higher side this time. So far there have been about 24 reported cases of ‘cloud bursts’ in the state but the monitoring, prediction and mitigation efforts are lagging far behind.

The factors that worsen the Uttarakhand Disasters

Abstract: While Uttarakhand is vulnerable to disasters, climate change is increasing these vulnerabilities. Major human interventions like hydropower projects and highways implemented without an informed or democratic decision-making process act as force multipliers during such disasters. The violations of legal and other prudent norms in their implementation further increase the damages. The absence of necessary monitoring, early warning systems and the overall disaster management system add another layer of damages during the disasters. The lack of the ability to learn lessons from disasters and lack of any accountability ensures the perpetuation of the situation.

DRP NB 22 Feb 2021: Case against NTPC for criminal negligence in Tapovan Project?

Consider these facts: The NTPC, the project developer, failed to appraise that the 520 MW Tapovan Vishnugad Hydropower project, where maximum damage and deaths occurred in Chamoli Avalanche disaster that started on Feb 7, 2021 morning, is in Paraglacial influence zone. Such an appraisal would have meant a number of implications, including possibly a decision that the project is geologically unviable.

NTPC failed to take any action to save the workers even after it was known upto 10-20 minutes before the disaster struck. Something that Mangshri Devi could do to save about 25 lives, NTPC could not do.

The project had faced several disasters since 2008, but fails to put in early warning system in place. For several days post disaster, reports say that NTPC failed to share even the detailed map of the tunnel where over 30 workers were stuck. NTPC’s disaster management system showed no signs of existence throughout the disaster. Reports say that the barrage gates were closed, which if they were open, it may have helped the flow of the flood debris downstream, which in turn could have possibly meant more time and saving of more lives.

चमोली आपदा: माँ के फोन कॉल्स से बच गई 25 जिंदगियां

फरवरी 7 को चमोली में आई विकराल बाढ़ अपने पीछे भीषण तबाही के निशान के साथ कुछ अहम सबक भी छोड़ गई है जो भविष्य में आपदा प्रबंधन को बेहतर बनाने में बहुत कारगार साबित हो सकते हैं।

ऐसा ही एक असंभव किस्सा स्थानीय महिला मंगसीरी देवी का है जिनका 27 साल का लड़का विपुल कैरेनी एनटीपीसी की तपोवन विष्णुगाड जल विद्युत परियोजना में कार्यरत है।

घटना के दिन विपुल की माँ मंगसीरी और पत्नी अनीता ने ऊचाई पर स्थित अपने गांव ढ़ाक से धौलीगंगा नदी में आई जलप्रलय को देखा। उसके बाद उसने अपने बेटे को कई बार फोन किया जिसके कारण उनके बेटे समेत 25 अन्य लोगों का जीवन बच गया।

DRP NB 15 Feb. 2021: Why Mangshri Devi of Tapovan Should Head Uttarakhand’s Disaster Management Department?

In a fantastic story, Shivani Azad of The Times of India has reported possibly the most remarkable story of the Chamoli avalanche disaster that started on Sunday morning on Feb 7, 2021. She reported that Vipul Kairuni of Dhaak village in Tapovan, working at the time at the now destroyed Tapovan Vishnugad project, got saved thanks to frantic calls by his mother Mangshri Devi as she and his wife saw from their village home, situated at a height from the river, that a massive flood is approaching the dam site. It was thanks to frantic, repeated calls by Mangshri Devi that not only Vipul, but at least two dozen more people could run to safety of a ladder and saved their lives.

So effectively, Mangshri Devi has saved at least two dozen lives in Chamoli disaster. Who else can claim to have achieved anything like that in the disaster? The disaster management department seems completely absent from the scene either in terms of pre disaster monitoring or in taking steps to save lives during the disaster. In fact, there should have been an early warning system in place that could have saved many more lives. But it does not exist. Either in Rishiganga/ Dhauliganga basin or anywhere else in Uttarakhand. NTPC’s Tapovan Vishnugad Project has faced so many disasters already since 2008, but is only now talking about putting in place early warning system. Should not the NTPC and power ministry top brass as well as Uttarakhand disaster management department held accountable for that?

Chamoli Disaster: CWC needs functioning, forecasting beyond monsoon

Feature image: CWC’s flow diagram map showing movement of flash flood in Alaknanda valley, Chamoli after landslide induced deluge on Feb. 7, 2021.

The landslide induced[i] flash flood disaster has left long-lasting trail of destruction along the Rishiganga-Dhauliganga-Alaknanda rivers. The flood sludge has filled up the riverbed after damaging infrastructures along the rivers. The rescue work still is underway.

The episode has reignited discussion on vulnerabilities of Uttarakhand, role of hydropower projects and climate change threats. Questions are being raised on destructive projects involving use of blasting, heavy machinery, tree felling challenging the resilience limits of fragile ecology of the region.

North India; CWC Flood Forecasting Sites 2020; New Website Old Problems

Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, intensity and flood damages. Accurate and timely flood forecasting can hugely help reduce the damages due to floods. Central Water Commission (CWC) is the only agency responsible for flood forecasting in India. To understand the CWC’s flood forecasting better, we have compiled the list of the various flood, inflow forecasting sites and flood monitoring sites in India.

In this compilation, we have given state wise list of CWC’s level forecasting, flood monitoring and inflow forecasting sites in North India, comprising of Union Territories Jammu & Kashmir, Ladakh, Chandigarh, Delhi and states of Himachal Pradesh, Uttarakhand, Punjab, Haryana  and Uttar Pradesh. It includes available details like name of river, sub basin, Warning level (WL), Danger Level (DL), High Flood Level (HFL), Full Reservoir Level (FRL), Maximum Water Level (MWL), as applicable. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list. A similar zonewise overview of CWC’s sites was compiled in 2018 and 2019, which can be seen here: Overview of CWC Flood Forecasting Sites 2018: North India; Overview of CWC Flood Forecasting Sites 2019: North India. We have brought this updated compilation for 2020 as there are large number of changes.

उत्तराखंड: जब मेरे गांव में बादल फटा

कमल पंवार का अतिथि लेख 

28 जुलाई के सबेरे तीन बजे के आस पास गाँव में कोलाहल मच गया। भारी बारिश के बीच गाँव के ऊपरी हिस्से और बगल वाले गदेरे में अचानक भारी गाढ़ आ गई। कुछ ही देर में तेज गर्जन से मलबे की धारा गाँव के पास से होकर गुजर गई और अपने पीछे बर्बादी का भयानक मंजर छोड़ गई।

क्षेत्र के बारे में

मैं चमोली जिले के बूरा, पडेर गाँवों की बात कर रहा हूँ। ये गाँव तिमदो तोक, विकासखंड घाट में पड़ते हैं। इन गाँवों की कुल आबादी लगभग 5000 है। केवल बूरा गाँव ही लगभग 2 किलोमीटर के क्षेत्र में चार अलग-अलग भागों च्याना, चांजलि, सीमार बसा है। बूरा से ऊपर की ओर उत्तर पश्चिम दिशा में पडेर गाँव लगभग दो किलोमीटर दूर है।
