Landslide detection in the Himalayas using machine learning algorithms and U-Net

Landslides, 2022
Event-based landslide inventories are essential sources to broaden our understanding of the causal relationship between triggering events and the occurring landslides. Moreover, detailed inventories are crucial for the succeeding phases of landslide risk

Atmospheric aerosol size distribution impacts radiative effects over the Himalayas via modulating aerosol single-scattering albedo

, 2023
The single-scattering albedo (SSA) of atmospheric aerosols is a key parameter that controls aerosol radiative effects. The variation of SSA is thought to be mainly regulated by aerosol absorption in the Himalayas and South Asia, but observations ...

An integrative method for identifying potentially dangerous glacial lakes in the Himalayas.

Science of the Total Environment, 2021
Glacial lakes in the Himalayas are widely distributed. Since 1900, more than 100 glacial lake outburst floods (GLOFs) have originated in the region, causing approximately 7000 deaths and considerable economic losses.

Challenges in Tunneling in the Himalayas: A Survey of Several Prominent Excavation Projects in the Himalayan Mountain Range of South Asia

Geotechnics, 2022
The Himalayas are one of the most unstable regions in the world. Underground excavations are very challenging in this region due to the fragile geology, tectonic activities and complex geological structures.

Understanding production possibility frontiers and utility values of ecosystem services in the Himalayas: An analysis of the supply-demand divide [PDF]

, 2023
Nature's services to humanity − ecosystem services (ES) − have been at the centre of natural resource management scholarship for the last few decades. Yet, quantification of ES supply and its economic valuation have dominated the academia.

Elevation Filters Lizard Species Occurrences and Assemblages in Chitwan Annapurna Landscape, Nepal. [PDF]

Ecol Evol
We investigated lizard species richness,assemblage patterns, and environmental drivers along the elevational gradient in the Chitwan Annapurna Landscape during 2018–2019. We recorded 23 lizard species and found that species richness varied significantly and non‐linearly with elevation, peaking at mid elevation. Species turnover dominated beta diversity,

Detecting Rock Glacier Displacement in the Central Himalayas Using Multi-Temporal InSAR

Remote Sensing, 2021
Rock glaciers represent typical periglacial landscapes and are distributed widely in alpine mountain environments. Rock glacier activity represents a critical indicator of water reserves state, permafrost distribution, and landslide disaster ...
