Cascading Hydropower Projects on Teesta River Basin

in Teesta River Basin construction of a series of cascade dams for hydropower generation is the most significant development activity in the state of Sikkim and West Bengal. Hydraulic model studies play a vital role in finalizing the design of spillway and energy dissipator of the hydro-power projects. The paper describes the hydraulic model studies of the cascading hydropower projects on Teesta River Basin namely, Teesta-iV, TLDP-iV and TLDP-iii conducted at Central Water and Power Research station, Pune, india for evolving the optimum design of spillways, energy dissipators and layout of power intake structures.
