| Zhuzhou constellation imagery — Gyirong County, 27 August 2026 | The preserved provider metadata describes an offline application route, while the theme supplies information rather than physical downloads. No no-cost acquisition condition or asset-specific authorization is established. The two inventoried assets are a listing and a preview, not the provider-reported science files. Current landing/API responses are interception pages despite HTTP 200. Exclusion is from this eligibility set, not a finding that the dataset does not exist. |

| ICIMOD Glacial Lakes and GLOF Hazard Database — Koshi and Gandaki Basins, Nepal & Tibet | The supplied DOI does not resolve and the two claimed file identities are not substantiated. ICIMOD does publish a related 2020 report under DOI 10.53055/ICIMOD.773, but that record does not verify the named GeoPackage or the supplied RDS DOI. Do not silently substitute the report for the alleged database. |
| Geological Map of Nepal 1:50,000 Sheet Series — Syabrubesi (GM53) and Dhunche (GM54) (Nepal DMG) | The named GM53/GM54 sheet identities and the two free PDF endpoints are not substantiated by the supplied official paths. A general DMG map programme does not verify these claimed files or the no-cost access condition. |
| Engineering and Environmental Geological Map of Bidur Municipality and Lower Trishuli (Nepal DMG) | The official DMG list confirms a 2019 Bidur engineering/environmental geological map, but states that displayed low-quality maps are publication information and usable maps must be purchased in person as hardcopy. The claimed free map/notes PDFs are unsupported. |
| Humanitarian OpenStreetMap Team (HOT) Building Footprints and Settlement Inventory (HOT Nepal) | A functioning general HOT export service does not substantiate the two named Rasuwa building/POI files. No original export job, manifest, extraction date or resource-specific geometry source is verified for these paths. |
| COMET LiCSAR Sentinel-1 Line-of-Sight InSAR Velocity Field and Time Series (Frames 085A & 019D) | The COMET portal and documented regional velocity products are real, but do not substantiate the two named frame velocity files or their claimed source-corridor series. Both proposed asset routes are unsupported. No pre-event creep interpretation follows from portal availability. |
| Flood-affected area — Upper Trishuli-1, Charter product 6073 | This is Charter product 6073, reference 1209-25, also catalogued under the areas potentially destabilised by flood erosion resource. Retain alternate URL provenance and correct the misleading Upper Trishuli 1-only title, but exclude a duplicate resource count. |
| Road blockages and recorded reopening dates in Rasuwa, Dhading and Chitwan — BIPAD, August–September 2026 | Seven BIPAD road records duplicate the seven primary DoR records under the paired resource. Retain provenance links but exclude a second independent resource/data count. Administrative statuses and source errors are preserved. |
| NRCS Rasuwa Flood Situation Updates1 and2,26–27August2026 | NRCS original page links authentic Update 1 dated 26 August andUpdate 2 dated 27 August. Both PDFs retrieved and text examined. Candidate filenames/dates were unsupported. Reports mix direct NRCS activity with attributed preliminary NDRRMA figures and tentative mechanism accounts; do not call all content field-validated. Authentic NRCS updates already occur in the original reviewed inventory. Retain this candidate as an alias to the existing NRCS resource and do not add a second resource. |
| Lirung Ice-Rock Avalanche and Cascading Disaster in Nepal: Scientific Briefing and Regional Technical Consultation | The exact claimed ICIMOD scientific-briefing PDF and its purported title/record were not established after original-site and record searches. The cited landing route returns 404 and the PDF route had a certificate failure; failure alone is not evidence of nonexistence, but neither route establishes the claimed attachment. Exclude the original report identity and unsupported method, bounds, licence and validation metadata. A distinct authentic ICIMOD event-resource HTML page is added separately as a mutable source index. |
| International Charter Space and Major Disasters: Call 1052 Flash Flood in Nepal (Rasuwa District) | The original generic Charter route does not identify either claimed JSON manifest or vector package and now returns 404. The authentic Call 1052 activation and individually identified products are already covered by Group B resource rec_81a54fd3-757b-5a39-952f-02d0bf778ead. Exclude this duplicate generic resource and both unsupported attachment identities; retain the linkage for provenance. |
| NDRRMA Disaster Situation Report: Rasuwa and Nuwakot Multi-Hazard Inundation and Casualty Register | The claimed ward-level casualty CSV and municipal damage GeoPackage both point only to the BIPAD portal HTML. Neither native attachment identity, claimed field-validation method, geometry, bounds or licence was established from the original source. Exclude the claimed resource and attachments. Actual BIPAD hydrology/alert/road resources are separately reviewed; they do not substitute for these alleged files. |
| Nepal Electricity Authority Technical Damage Assessment: Trishuli River Basin Hydropower Installations | The claimed NEA technical damage assessment and hydropower forensic ledger point only to the agency homepage, which returns HTML rather than the alleged PDF. Original-source searches did not establish this exact attachment or the claimed diver/structural validation method. Exclude the claimed report and all unsupported size, geographic, rights and validation metadata; agency news or secondary loss estimates are not substitutes for this ledger. |
| GPM IMERG Final Precipitation V07 — Half-hourly and daily spatial precipitation over central Nepal (August 2026) | The named August2026FinalRun files were not established in a native inventory; NASA documents approximately2.5–3.5months FinalRunlatency. No supplied evidence establishes their availability by24September2026. Do not substitute Early/LateRun silently. |
| Hydrodynamic simulation and inundation mapping of the 2026 Bhote Koshi flash flood using coupled 1D-2D modeling | The claimed original EarthArXiv paper, PDFroute and CrossrefDOI all fail identity verification. Exact Crossrefx58p12 and PDF25840routes return404. Exclude the unverified named paper from the eligible inventory. |
| InSAR coherence loss and ground displacement preceding the 2026 Langtang Lirung rock-ice avalanche | Original arXiv2609.08123 is the unrelated robotics DISEIL paper. Exclude the wrongly identified Bhatt/Dhakal Langtang study and both associated records. |
| Upper Trishuli-3B Hydroelectric Project — Detailed Engineering Design and Flood Frequency Report (NEA) | The named UpperTrishuli3B designPDF returns404 and no native original attachment was established. The existence of the company does not verify this document or the claimed numerical engineering content. |
| Rasuwagadhi Hydroelectric Project — Corridor Geotechnical and Environmental Impact Assessment (MoFE / NEA) | The specific Rasuwagadhi EIA and annex identities were not established through original native records; the supplied MoFEroute could not be inspected. Exclude these unverified named holdings from eligible counts while preserving the discovery record. |
| Gyirong Landslide-Dammed Lake Measurements and Emergency Outflow Bulletins (Ministry of Water Resources, China) | The generic MWRportal and secondary Xu citation do not establish the specifically named bulletinPDF or hydrographCSV. No original file identity, observation table or licence was recovered. Exclude the alleged holdings from eligible counts; preserve source leads. |
| Unverified DHM event hydrograph and station-failure package | The declared CSV and station-failure PDF both link only to a generic homepage. Neither specific file nor the claimed persistent identifier was established. The verified CHWRR report and DHM series are separate candidate records; do not count this unsupported aggregate again. |
