Search method
Query IFC disclosure portal for Upper Trishuli-1 (Project 35701) Dam Management Plan and Environmental Flows Assessment; query NWEDC and Trishuli Jal Vidhyut for Upper Trishuli-3B design specifications; query MoFE for Rasuwagadhi HPP transmission-line EIA. Retrieve public engineering documents and baseline data.
Criteria
CriterionAll languages. Trishuli and Bhote Koshi hydropower projects (UT-1, UT-3B, Rasuwagadhi). Baseline engineering documentation.
Coverage
Detailed reach-scale channel geometry, rating curves, flood frequency estimates (100-year and PMF), and geotechnical slope stability reports along the corridor.
Stopping rule
Exhaust publicly disclosed engineering reports and environmental/social impact disclosures for the targeted hydropower schemes.
Result

3 hydropower engineering resources recovered across 6 assets: Upper Trishuli-1 Dam Management Plan & E-Flows bathymetry, Upper Trishuli-3B Detailed Design Report, and Rasuwagadhi HPP EIA.
