One of the most significant features of a dam for flood protection is the spillway. Determining the hydraulic parameters of a spillway can be difficult due to the constantly changing flow type. For the objective of generating an effective design for the spillway of the Maithon dam in Dhanbad, Jharkhand, India, numerical model studies were conducted. An ogee spillway and energy dissipator models were examined in this study to see if they could improve energy dissipation and trajectory length, by using ANSYS Fluent 19.0.2D software models were developed for different profile with maximum discharge 13592 m3/s. The numerical simulations using this design showed how the energy dissipator's design must be changed in order to provide proper energy dissipation and the best possible flow in the river downstream of the spillway. After going through numerical model simulations, a modified energy dissipator design in the shape of a ski-jump bucket with a wedge close to the lip was designed to reduce energy loss.
