Decoupling of erosion and precipitation in the Himalayas.
The hypothesis that abrupt spatial gradients in erosion can cause high strain rates in active orogens has been supported by numerical models that couple erosional processes with lithospheric deformation via gravitational feedbacks. Most such models invoke a 'stream-power' rule, in which either increased discharge or steeper channel slopes cause higher erosion rates. Spatial variations in precip...
متن کاملGlacial Lakes in the Himalayas: A Review on Formation and Expansion Processes
In the recent several decades, glacial lakes have been expanding at the terminus of debris-covered glaciers associated with glacier shrinkage in the Himalayas. Accordingly, glacial lake outburst floods (GLOFs) have become serious natural disasters in the Himalayas. Bathymetrical surveys have been carried out at several glacial lakes, and the relationship between the lake area and water volume h...
متن کاملCorrection: Glacial Lake Expansion in the Central Himalayas by Landsat Images, 1990–2010
Glacial lake outburst flood (GLOF) is a serious hazard in high, mountainous regions. In the Himalayas, catastrophic risks of GLOFs have increased in recent years because most Himalayan glaciers have experienced remarkable downwasting under a warming climate. However, current knowledge about the distribution and recent changes in glacial lakes within the central Himalaya mountain range is still ...
متن کاملDevelopment and Validation of New Glacial Lake Inventory in the Bhutan Himalayas Using ALOS ‘DAICHI’
This study aims to develop and validate a new glacial lake inventory in order to gain an understanding of existing conditions. This is being done using optical imageries acquired by the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) onboard the Advanced Land Observing Satellite (ALOS, nicknamed ‘Daichi’). ...
متن کاملClimatic forcing of erosion, landscape, and tectonics in the Bhutan Himalayas
A fundamental objective in studies of climate-erosion-tectonics coupling is to document convincing correlation between observable indicators of these processes on the scale of a mountain range. The eastern Himalayas are a unique range to quantify the contribution of tectonics and climate to long-term erosion rates, because uniform and steady tectonics have persisted for several million years, w...
