Abstract

In 2021, a catastrophic flood occurred in the Melamchi Valley of Nepal, causing widely distributed erosion in Himalayan headwaters and mobilizing a large sediment volume. As the flood progressed downstream, it induced an erosional cascade, producing 100 m deep incisions into high-elevation valley fills, generating new landslides and burying the lower reaches in alluvium. This event demonstrated the destructive impact of cascading processes and their potential for reshaping the landscape.
