报告简介：

The Asian Highland is one of the seismically active mountain belts in the world with several kilometers of relief and very prone to catastrophic mass failure. The coupling effect of seismo-tectonic activities and Asian rainfall is triggering numerous water-induced hazards. The recent events such as Seti Flood (2012), Chamoli flood (2021), Melamchi debris flow (2021) and Lhonak lake burst (2023) have shown the scale of devastation in this region. The Seti Flood was created due to a large rock slope failure occurred at Sabque Crique, Annapurna range, Nepal. The collapsed material transported the whole material deposited in the upstream of the Seti River creating large scale debris flow. Similarly, the catastrophic debris flow at Melamchi Bazaar killed at least 5 people and damaged major infrastructures including Melamchi Water Supply Project. This debris flow caused wide-spread aggradation along tens of kilometer of Melamchi River corridor, with up to 15 meters of deposition in the town of Melamchi Bazaar. These cascading events highlight the importance of understanding paleo-landslide dam, glacial moraine, or other geomorphic process in the mountain catchment.
