Nepal Flood 2026 River Corridor, Bhote Koshi and Trishuli

Completed catalogue assessment

Eligibility decision: Include · Included Resource
Assessment date: 28 September 2026
Decision reason: All 71 original child URLs match the original HOT HDX resource list and their public native bodies or file headers were assessed. This is a 1 km river-corridor planning/context inventory; its bounds are not the event flood extent. OSM and Overture sources and their provenance remain separate. Alternate file formats do not constitute independent observations; current mutable files were assessed on 28 September.

Persistent identifier: 70dc945d-fd9c-4248-b7e8-26700b042641
Resource version: Mutable daily HDX export; metadata state observed 3 September 2026
Publication date: 27 August 2026
Last updated: 3 September 2026
Metadata reviewed: 28 September 2026
Language: English
Geographic coverage: River corridor from Rasuwagadhi to the Narayani confluence at Devghat across Rasuwa, Nuwakot, Dhading, Gorkha, Tanahu, and Chitawan.
Bounding box (WGS 84): [84.273839,27.6559453,85.4306907,28.3305113]
Temporal coverage: Until 3 September 2026; Mixed
Themes: Infrastructure, Exposure, Response Planning, Baseline Geography, Crowdsourced Mapping

Method and provenance

Production method: A fixed 1 km buffer was constructed around river centrelines from Rasuwagadhi to the Narayani confluence, merging a partner upper-reach shapefile with OCHA's Humanitarian Programme Cycle Tools and Services corridor. OpenStreetMap and Overture layers were extracted for that planning area.
Provenance: Published by HOT through HDX. Component layers derive from OpenStreetMap and Overture Maps; the corridor geometry combines partner and OCHA sources.
Validation: Unclear
Uncertainty: OpenStreetMap coverage varies with mapping activity. Overture combines multiple upstream sources, including machine-generated content, and follows a different release cycle.
Limitations: The 1 km corridor is a planning boundary, not an observed or modelled inundation extent; presence inside it does not indicate exposure or damage.
