Abstract: Consideration of several buckets, of type used to deflect or flip tunnel spillway discharges downstream, in terms of their desirable or undesirable features; new types of buckets developed from hydraulic model tests are described; dimensionless curves aid in determining jet trajectory length, spreading of jet, tail water drawdown at bucket, and pressures on floor and side walls of bucket.
