One parameter of spillway design is the largest flood it is designed to handle. The structures must safely withstand the appropriate spillway design flood (SDF), sometimes called the inflow design flood (IDF). The magnitude of the SDF may be set by dam safety guidelines, based on the size of the structure and the potential loss of human life or property downstream. The magnitude of the flood is sometimes expressed as a return period. A 100-year recurrence interval is the flood mag… Web(a) Trajectory (or Deflector) Bucket: When tail water depth is lower than the depth required for the jump formation and the bed of the river channel is composed of sound rock capable of withstanding the impact of trajectory jet, trajectory bucket (also known as deflector or ski-jump bucket) (Fig. 11.6) is generally used as energy dissipator.
