Catalog Description

411 Open Channel Hydraulics. I or II; 3cr. Analysis and characteristics of flow in open channels (natural and artificial); channel design considerations including uniform flow (rivers, sewers), flow measuring devices (weirs, flumes), gradually varied flow (backwater and other flow profiles, flood routing), rapidly varied flow (hydraulic jump, spillways), and channel design problems (geometric considerations, scour, channel stabilization, sediment transport). P:CivEngr 311.

Selected readings from other books and articles

Course objectives

Observe and understand types and characteristics of flow in open channels (natural and constructed)
Develop ability to use one-dimensional, conservation laws (mass, energy, momentum) to analyze steady and unsteady, gradually and rapidly varied flows in rigid boundary channels
Understand and use design methods for rigid and moveable, boundary channels
Develop and apply discharge relations to flow measurement structures
Introduce methods to control channel geometry and sediment movement in natural channels

Topics covered

Energy and momentum relations for steady flow (specific energy, specific force, critical depth)
Measurement devices and methods for depth, velocity and flow
Velocity and shear distributions, discharge relations (Manning's equation), and channel design (non-erodible, erodible, grassed) in steady, uniform flow
Computation of water surface profiles (energy and mass conservation equations), effects of channel geometry (width, alignment, junctions) and structures, and channel resistance and sediment movement in steady, gradually varied flow
Depth and velocity changes (mass and momentum conservation relations) with application to hydraulic jumps, channel transitions and waves in steady, rapidly varied flow
Unsteady flow computation for gradually varied conditions (flood routing methods) and for rapidly varied conditions (surge and dam break methods)
River engineering problems and approaches for channel control, sediment control, and effects of structures

Class/laboratory schedule

Two 50 minute lectures and one 2 hour discussion/laboratory per week

Contribution of course to meeting the professional component

This course contributes primarily to the students' knowledge of engineering topics, and does provide design experience.

The following statement indicates which of the following considerations are included in this course: economic, environmental, ethical, political, societal, health and safety, manufacturability, sustainability.

Analysis tools are presented and used for steady and unsteady, one-dimensional, uniform, gradually varied, and rapidly varied flows in rigid boundary, open channels (natural and constructed); tools are basis for assessing environmental impacts of proposed channel alterations Design methods are used to select the geometry of non-erodible, erodible, and grass channels to meet economic and environmental considerations Types, characteristics and selection of flow measurement structures are presented and used with consideration of environmental and safety effects Methods of river engineering with environmental and safety aspects are introduced

Assessment of student progress toward course objectives

Assessment is performed with examinations, laboratory reports, design project, and homework (problem) assignments.
