By way of this undertaking, which additionally includes JNU, Sikkim College and different Institutes, the chance from sudden lake outbursts will probably be quantified by way of bathymetric surveys and 2D/3D flood modelling from the chosen lakes.
Bathymetric surveys are specialised hydrographic surveys that map the depths and shapes of underwater terrain. The method offers detailed details about the underwater topography of a water physique.
It is going to give attention to Tenbawa Lake Glacial Lake Outburst Flood potential and Holocene Local weather linkages in Sikkim and two different glacial lakes in Arunachal Pradesh.
The Researchers intend to determine ‘Probably Harmful Glacial Lakes' utilizing high-resolution knowledge and analyse geomorphology, permafrost and slope instability within the Tawang area of Arunachal Pradesh and in Lachung basin of North Sikkim below two separate tasks.
The chance from sudden lake outbursts will probably be quantified by way of bathymetric surveys and 2D/3D flood modelling from choose lakes within the Tawang area.The undertaking additionally seeks to determine ecological dangers, information gaps and ecosystem companies associated to high-altitude lakes below the up to date local weather change, in addition to the evaluation of saved freshwater assets.The outcomes of this investigation/analysis will probably be shared with policymakers, planners and builders for a holistic growth alongside the banks of the streams and rivers to mitigate the impression of devastation on account of a ‘Glacial Lake Outburst Flood' occasion, thus saving the post-disaster haphazard rescues, insurances and rebuilding of buildings.
This undertaking is funded by the Ministry of Earth Sciences and the Ministry of Atmosphere, Forest and Local weather Change, Authorities of India. It's led by Dr. Manasi Debnath, Nagaland College, who's the Principal Investigator.
Highlighting the necessity for such research, Prof. Jagadish Okay Patnaik, Vice-Chancellor, Nagaland College, mentioned, “Nagaland College takes nice pleasure in main a essential analysis initiative geared toward growing an in depth and near-accurate stock and stability evaluation of high-altitude lakes within the Sikkim and Arunachal Himalayas. This multidisciplinary undertaking focuses on understanding the Glacial Lake Outburst Flood (GLOF) potential of Tenbawa Lake and its linkages to Holocene Local weather variations.”
Patnaik added, “Such scientific efforts are very important in addressing the growing environmental vulnerabilities within the japanese Himalayas, enhancing our preparedness for pure hazards, and deepening our understanding of previous local weather dynamics. This undertaking is a testomony to Nagaland College's dedication to advancing frontier analysis for societal and ecological resilience within the Northeast area and past.”
Dr. Manasi Debnath, Assistant Professor, Division of Geography, Nagaland College, mentioned, “We're working to create a exact stock of glacial lakes within the Jap Himalaya (North Sikkim and Arunachal Himalaya) and consider the harmful lakes when it comes to breach potential and quantity of discharge. These can be carried out utilizing excessive spatial decision satellite tv for pc photos, and mandatory discipline validation and measurement for the potential lakes.”
Highlighting what makes this analysis distinctive, Debnath added, “We suggest to evaluate the glacial lakes of Arunachal and Sikkim, which haven't been studied intimately for breach traits and space being impacted resulting from inundation on the time of GLOF, the size and reaches affected. Because the evaluation of the Arunachal glacial lakes is on the headwaters of the Brahmaputra, any lake breach will be devastating when it comes to the size of attain. In Sikkim, the ecological impacts below such circumstances are additionally being studied on the Lachung sub-basin degree. Palaeo-hazard evaluation on the Lachung sub-basin within the Sikkim Himalaya aids in evaluating previous and current GLOF frequencies on the basin scale.”
The geographical peculiarity of those glacial lakes, the impression of local weather change of the thawing mechanism of permafrost, and a regional sample when it comes to the speed of recessions and ice loss in glaciers of the Jap Himalaya compared to the Western Himalaya and the remainder of excessive Asia.
Drone mapping and bathymetry surveys of the glaciers and glacial lakes would assist produce a near-accurate database for modelling of doable associated disasters for sturdy growth alongside the reaches of the streams emanating from these glaciers and lakes, and the river downstream. Palaeo-studies goal to deduce the extent of local weather change within the geological previous, serving to to know the present debate between human-induced and pure local weather variability.
This undertaking will additional assist in the event of the newly established lab on the Division of Geography, Nagaland College, named ‘Glacier and Mountain Analysis Lab.'
The Co-Principal Investigators embrace Dr. Milap Chand Sharma Senior Professor in Geomorphology, CSRD Jawaharlal Nehru College, Delhi, Dr. Rajesh Kumar, Division of Geography Sikkim College, Dr. Mriganka Shakar Sarkar Scientist-B G.B. Pant Nationwide Institute of Himalayan Atmosphere, Itanagar, and Dr. Pankaj Kumar Scientist-F and Group Head of Accelerator Mass Spectrometry and Geochronology, Inter-College Accelerator Centre (IUAC), Delhi, which is a companion group. Samikcha Rai, Junior Challenge Fellow and PhD Scholar Division of Geography, Nagaland College, can be among the many researchers engaged on this undertaking.
