Cloud burst incidents are on the increase across Himalayan states. The states of Uttarakhand and Himachal Pradesh have faced 23 and 16 cloud burst incidents in the south west monsoon 2019. This account compiles such reports from Jammu Kashmir (J&K) and north eastern Himalayan states.
Cloud burst incidents are emerging as a major threat for the Himalayan states. Of late, the extreme weather event have been causing large scale destruction in ecologically sensitive and remotely located vulnerable hilly areas. In 2018 between May 2 and July 20, the Uttarakhand state saw around 13 cloud bursts event which have increased to 23 in 2019 monsoon season resulting in wide scale damages.
This compilation for Himachal Pradesh state shows that the state is suffering even bigger destruction of infrastructure including roads, buildings, bridges and hydro projects due to increasing cloud burst events. At the same time the monitoring and mitigation efforts are totally insufficient and inadequate.
With the beginning of south west monsoon season 2019, many Himalayan states started witnessing exceptional rainfall events known as Cloud Bursts. The extreme weather event – like previous years- caused large scale destruction in ecologically sensitive and remotely located vulnerable hilly areas. This account compiles the available information about such incidents in Uttarakhand in 2019 SW monsoon.
Interrogating Cauvery Calling N Ram questions Jaggi Vasudev’s Cauvery Calling, asks why it shifts goal posts Speaking at Interrogating Cauvery Calling seminar in Chennai, N Ram said that various state governments and the central government that endorses the project should also be questioned.
“Now a very serious issue that must cause concern is the raising of public interest and public money for this project. Truly mega, in terms of money involved – 242 crore trees, 11,000 crore rupees. That is the kind of money involved. Only 0.5% collected. There is still time to put checks on this and prevent this from going further,” he said. “What is the management of this money? Who oversees it? There is no transparency, no verifiable document, no clear management structure for huge amount targeted. It is a matter of great concern.”
– N Ram also said that various state governments and the central government that endorses the project should also be questioned. “As a political journalist, this is the question that occurs to me. Who gave the Isha Foundation the right, the jurisdiction to transgress on what should be the commons. And why are governments being subservient to this idea? Apart from the risks, probable negative outcomes and over simplification of solutions for Cauvery, this is what is worrying,” he concluded. https://www.thenewsminute.com/article/n-ram-questions-jaggi-vasudevs-cauvery-calling-asks-why-it-shifts-goal-posts-112838 (24 Nov. 2019)
गत 23 जून 2019 को, उत्तराखंड की चौथान पट्टी में तेज और असामान्य बरसात हुई। थलीसैंण तहसील के अंतर्गत लगने वाली चौथान पट्टी में 72 गांव आते हैं। पौड़ी जिले के दूरस्थ क्षेत्र में बसी चौथान पट्टी, दूधातोली आरक्षित वन के बफर जोन के आस पास बसी हुई है। साथ में यह पट्टी अल्मोड़ा और चमोली जिले की सीमाओं से सटी हुई है।
(“इति जोरग बरख लागि छ, हम भैर-भीतर नि अय स्की, हमूल अपण जमन मै यैस अंधकोप नी देख, हमूल जाण याल छ, गाढ़-गेदरयुग गुगाट, जरूर कखि ढोल-फ़ोल करल”) “इतने जोर से बारिश हुई थी कि हम लोग घरों में कैद हो गए। हमारी याद में ऐसी घनघोर बरसात पहले कभी नहीं हुई। गाड़ गदेरों में आई बाढ़ की गड़गड़ाहट से ही हम समझ गए थे, कहीं कुछ नुकसान जरूर होगा”, स्यूंसाल गांव की एक बुजुर्ग महिला ने बताया।
बारिश रविवार शाम लगभग तीन बजे के शुरू हुई और करीब दो घंटे तक लगातार चलती रही। अतिवृष्टि के दो बाद ग्रामीण लोग इसे बादल फटने की घटना मान रहे हैं और इलाके में इससे हुए नुकसान की सूचनाएं किस्तों में मिल रही है।
Heavy and unusual rainfall struck, Chauthan Patti, on June 23, 2019. The region is comprised of 72 villages in Thailisain Tehsil of Pouri Garhwal, Uttrakhand. The remote mountain region is settled in and around buffer zone of Dudhatoli reserve forest. It also borders the Almora and Chamoli districts of Uttarakhand.
(“इति जोरग बरख लागि छ, हम भैर-भीतर नि अय स्की, हमूल अपण जमन मै यैस अंधकोप नी देख, हमूल जाण याल छ, गाढ़-गेदरयुग गुगाट, जरूर कखि ढोल-फ़ोल करल”) “It rained so heavily that we could not move from inside-out vice a versa, we had never seen such a heavy downpour in our lifetime, the streams were full and roaring, we had guessed, it would certainly cause damages” said an elderly woman of Syunsal village, in Garhwali language.
The rain lasted for about two hours beginning around 3 pm. Two days after the deluge, which many villagers are now terming as cloud burst, the details of damages is coming out, though in piece meal.
ASSAM: NEEPCO a repeat offender? On July 27, 2018 sudden release of water from NEEPCO’s Doyang Hydropower Electric Project (HEP), located in Wokha district, Nagaland led to flood disaster, submerging about 36 villages in Golaghat a district in Upper Assam. According to Rony Rajkumar, project officer of the Golaghat district disaster management authority, around 5,575 people were affected by the deluge which damaged 887.9 ha of crop.
Earlier, on July 11, 2018, reviewing the severe flood situation Lakhimpur Assam, the Chief Minister (CM) Sarbananda Sonowal strongly warned the state-owned power utility NEEPCO not to release water from its Ranganadi dam without warning like previous years.
Himachal Pradesh has received 917.3 mm rainfall during South West Monsoon 2018. The amount is 11 percent higher than normal rainfall category of 825.3 mm. However at district level there is considerable variation in the distribution of rainfall. Out of 12 districts in the state, rainfall departure has been in deficit in three districts namely Chamba, Kinnaur and Lahul & Spiti by 38 percent, 32 percent and 43 per cent respectively. All these three districts are in upper part of Himalaya, the origin of many rivers & where mountains are mostly snow covered.
Dams and reservoirs make rivers sediment-starved and menacing manifold downstream. While heavy rainfall is also a key factor behind the floods, hungry water had a more pronounced effect, says D. Padmalal, Scientist and Head, Hydrological process group, National Centre for Earth Science Studies.
– “When the sediment transport is interrupted, the potential energy of the hungry water released from dams will scour the river banks downstream, uprooting trees or riparian vegetation and damaging bridges and other engineering structures,” explains Dr. Padmalal. Overloaded with silt and clay from the eroding river banks, the highly turbid and viscous water clogs drainage channels. Subsequent discharge of water from the dam will lead to inundation and waterlogging of large areas.
– Hungry water can also develop in high gradient river channels devoid of adequate quantity of sand and gravel, especially during periods of high rainfall. “Years of uncontrolled sand mining have left most of the rivers in Kerala depleted or exhausted of sand and gravel. This creates a situation similar to the release of hungry water from dams,” notes Dr. Padmalal. When the river channel has adequate supply of sand and gravel, the potential energy of the water is used to transport the mixture. The water does not scour the banks or turn muddy.
The various aspects of tragic Dam Disaster in Mekong Basin in Laos are still unfolding. But it is clear from many accounts that it was an avoidable, man-made disaster due to neglect of contractors, decision makers, consultants and supervising agencies. There is a lot we can learn from this if we want to avoid such disasters in India. We still do not have credible Dam Safety Law or institution, CWC is clearly not the right agency considering the conflict of interest with the various other roles of CWC. But for now let us look at the reports of Laos Dam Disaster.
Reminding the world of one of the worst dam disasters, the under construction dam Xepian Xe Nam Noy Hydro power project breached releasing 5 billion cubic metres of water in Southern Laos on July 23.
The gushing water current swept the surrounding leading to death of about 26 people and displacing about 6600 residents. As per report hundreds of people are still missing from neighbouring villages of Yai Thae, Hinlad, Mai, Thasengchan, Tha Hin, and Samong, which bore the brunt of flooding. The deluge has reportedly destroyed thousands of homes.
