Remote sensing interpretation of development characteristics of high-position geological hazards in Sedongpu gully, downstream of Yarlung Zangbo River
Sedongpu gully is a branch gully on the left bank of the lower reaches of the Yarlung Zangbo River. It is located below the galabaire peak. It often accumulates abundant moraines and loose deposits every year. Affected by temperature, rainfall and earthquake, high-position geological disasters have...

| description | Sedongpu gully is a branch gully on the left bank of the lower reaches of the Yarlung Zangbo River. It is located below the galabaire peak. It often accumulates abundant moraines and loose deposits every year. Affected by temperature, rainfall and earthquake, high-position geological disasters have occurred many times and caused the blockage of the Yarlung Zangbo River. Through field investigation, combined with Landsat and other multi-source and multi-phase remote sensing images and InSAR radar data, the development characteristics of high-position geological disasters in Sedongpu gully are analyzed, and the existing deformation bodies are interpreted and analyzed: There are many glaciers, collapses, landslides and ice lakes in sedongpu gully; In the past 20 years since 2001, there have been five high-position geological disasters blocking the mainstream of the Yarlung Zangbo River; There are 3 identified deformations and 2 suspected deformations in the upper part of the gully; According to the two high-position geological disasters occurred in 2018 in Sedongpu gully, it is considered that the provenance comes from one high-position rock avalanche area and three high-position ice avalanche areas. This paper provides preliminary data for the further study of high-position geological disasters in Sedongpu gully, and provides effective scientific ideas for the study of similar geological disasters. |
