Remote sensing-based hazard assessment of glacial lakes in Sikkim Himalaya
Glacial lake is a water body formed in/under/besides and/or in front of a glacier due to glacial dynamics. Such high-altitude glacial lakes are hazardous to humanity and infrastructure as they can drain instantaneous and create devastating floods in the downstream. The formation of moraine-dammed glacial lakes and glacial lake outburst flood (GLOF) is major concern in countries such as Bhutan, ...
متن کاملEvaluations for Potential of Glacial Lake Outburst Floods (glofs) in the Bhutan Himalaya Using Prism and Avnir-2 Onboard Alos
The objectives of this study are to validate generated Digital Surface Models (DSMs) by PRISM onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”) in snow and glacier regions to contribute to the evaluation of potential Glacial Lake Outburst Floods (GLOFs) and their mitigation in the Bhutan Himalaya. Glacial lake inventory will also be generated to investigate the expansion ...
متن کاملDigital landscapes of deglaciation: Identifying Late Quaternary glacial lake outburst
High resolution DEMs obtained from LiDAR topographic data have led to 9 improved landform inventories (e.g. landslides and fault scarps) and understanding of 10 geomorphic event frequency. Here we use airborne LiDAR mapping to investigate 11 meltwater pathways associated with the Tweed Valley palaeo ice-stream (UK). In particular 12 we focus on a gorge downstream of Palaeolake Milfield, previou...
متن کاملAnatomy of terminal moraine segments and implied lake stability on Ngozumpa Glacier, Nepal, from electrical resistivity tomography (ERT)
Moraine-dammed lakes at debris-covered glaciers are becoming increasingly common and pose significant outburst flood hazards if the dam is breached. While moraine subsurface structure and internal processes are likely to influence dam stability, only few sites have so far been investigated. We conducted electrical resistivity tomography (ERT) surveys at two sites on the terminal moraine complex...
متن کاملLate Pleistocene earthquake-triggered moraine dam failure and outburst of Lake Zurich, Switzerland
[1] Lakes impounded by moraines may be considered hazardous in glaciated areas throughout the world because dams can fail suddenly producing destructive floods with peak discharges far in excess of normal flows. Here we present a comprehensive case study in the Zurich, Switzerland, area that reveals several independent lines of evidences for the occurrence of a Late Pleistocene ( 13,760 calibra...
