Summary

This journal article identified high and very high flash flood risks in sub-basins B, F, and N, followed by F, I, K, and L. These findings align with past flood records. Flash flood risk is concentrated upstream due to steep terrain and excessive precipitation. Remote sensing data proves crucial for basin-scale morphometric analysis in identifying such risks. Notably, Hetauda and east Bharatpur, growing cities in the region, are situated in high-risk zones. As flood susceptibility varies across the basin, urban planners should prioritize these risk areas, particularly the major cities, for effective mitigation strategies. The result shows that the drainage density, topographic relief, and rainfall intensity have mainly contributed to flash floods in the study area. Hence, flood risk was analyzed pixel-wise based on slope, drainage density, and precipitation.
