Nepal Flood Emergency Logistics & Air-Ground Dispatch Corridor

Geomorphic Vulnerability: Nepal's steep mid-hills and tectonic gorges make key arteries (BP Highway, Prithvi Highway, Araniko Highway) prone to simultaneous debris flows and river bank erosion following cloudburst events.

The Air-Bridge Tradeoff: While military rotorcraft (NA Mi-17s and light Eurocopters) bypass landslide closures directly into high elevations, their payload is limited (2–4 MT) compared to heavy commercial truck convoys (15–25 MT). Sustainable relief requires balancing rapid air drops with bulldozed road openings.

Last-Mile Distribution: In extreme cut-off zones like Melamchi and Roshi, riverbeds convert into temporary dirt tracks once peak flood discharge recedes, requiring high-ground staging warehouses.
