The Chenab River basin in India offers substantial potential for hydropower generation due to its steep topography and perennial flow. The Kwar Hydroelectric Project, a prominent run-of-river initiative on the Chenab River in the Kishtwar district of Jammu and Kashmir, necessitated an in-depth hydraulic assessment of its spillway and energy dissipation system. This paper presents the outcomes of both 2D sectional and 3D comprehensive physical model studies carried out. The studies reveal that there is a significant enhancement of spillway energy dissipation design such as optimization of spillway profile, refined geometry of ski-jump bucket and measures to improve downstream protection. Collectively, these modifications contribute to achieve superior hydraulic efficiency, enhance operational safety, and greater cost-effectiveness-underlining the vital role of physical modelling in the design and refinement of complex hydropower infrastructure.
