CE 458 Design of Hydraulic Structures

Credit Structure: (2-2) 3

Catalog Description:
Dam design concepts. Design of overflow and outlet structures; frontal overflow, side channel, morning glory overfall, siphon, free fall, chute, cascade spillway. Design of dissipation structures; hydraulic jump and stilling basin, drop structures and plunge pools, trajectory basins. Design of bottom outlets; gate types, hydraulics of high-head gates, air entrainment, cavitation. Design of intake structures; hydraulic losses, vortex formation, hydraulic loadings, control gates and valves, penstock.

Course Objectives:
• Integrate the hydraulics and water resources background by involving the students in dam design applications.
• Introduce the students to professional practice and design codes.
• Encourage class discussions for formulating and solving multi-variable hydraulic design problems in an open-ended solution space.
• Prepare, submit and present hydraulic engineering design material.
