Short summary
Glacial lake outburst floods (GLOFs) continue to threaten high-mountain communities in Nepal. We simulate potential GLOF events from five glacial lakes in the Everest region during the 21st century using a 3D flood model and several breach and SSP scenarios. Large GLOFs could extend over 100 km and inundate 80 to 100 km of roads/trails, 735 to 1989 houses and 0.85 to 3.52 km2 of agricultural land. The results help to assess the changing GLOF impacts and support more accurate risk assessments.
