Extended Data Fig. 7: Geomorphic impacts of the 2021 flood in the lower reaches of Melamchi Khola.

From: Erosional cascade during the 2021 Melamchi flood

Extended Data Fig. 7

Massive aggradation (15–23 m) was observed on the riverbed near Kyul. Following change detection indicates rapid evacuation of sediment (1–6 m lowering between Oct 2021 and Dec 2023). Intense lateral erosion and large slope failure at where the river curves near Talamarang. The slope failure extended further upslope during Oct 2021-Dec 2023.
