Heavy monsoon rainfall, excessive snowmelt and unstable terrain combined to cause the 2021 Melamchi Valley flood disaster in Nepal, according to new research. The findings highlight how a mix of climate and geological factors intensify disaster risks. The study also shows the value of using high-resolution satellite imagery and digital models of Earth’s surface to map landscape changes, create early-warning systems and improve flood preparedness, especially in remote areas.   Click here to read the story.   Click the following link for more information on Flood.
