A 100 MW Hydro Power Project is planned on Trishuli River in central Nepal. The project is located along the Kathmandu Pokhara ‘Prithvi’ Highway, and it is a run-of-the-river type project with Dam Toe Powerhouse arrangement having a capacity of 100 MW of power generation. The project is planning to install very high radial gates. A two-dimensional physical model is built to evaluate the performance of energy dissipation arrangement provided in the form of stilling basin at downstream of spillway. The model is called two dimensional, as only one or two spans are reproduced in the model, out of total five spans of spillway. Model studies highlighted the need to lower the height of radial gates and addition of one or two spans of spillways, to improve the energy dissipation arrangement. The improvement in stilling basin is also suggested. The further studies are ongoing.
