Devighat Intake Model Study

Research institution: Hydro Lab

The prime objective is to carry out a physical model test of Trishuli outlet for finding alternatives to abstract design discharge into Devighat conveyance system.

The achievements from the model test are: 1) to ensure that the storage in the upstream of the diversion weir is sustainable subject to proper headworks operation, and 2) to verify the satisfactory performance of the designed headworks with minor modifications.
