Abstract: The hydraulic conditions for pressure hydraulic jump in the circular culvert pipe under the dam with gate are explored. The calculation method for the position of pressure hydraulic jump in the culvert pipe is proposed, and the corresponding formula for calculating the outlet water depth of culvert pipe is derived, and the specific calculation steps are provided with an example.

Key words: culvert pipe under dam, flow control by gate, hydraulic calculation
