Students that successfully completely this subject will have the skills to practice under a chartered engineer to analyse problems and propose designs in the field of civil and environmental hydraulic engineering. Analysis of water flow in natural and constructed channels is studied in the river hydraulics module. This gives students the fundamental tools to learn techniques such as flood prediction, the design of channels for water movement in irrigation, and the prediction of water levels in channels in environmental flow studies. The movement of water and sediment along coasts due to wave action and currents is the focus of the coastal hydraulics module. An understanding of wave processes in coastal and surf zones is an essential starting point for the design of coastal structures such as piers, groins and jetties. With impending sea level rise, this will be a significant area of civil engineering practice for the foreseeable future. In the third module, the focus will be on processes of sediment transport and geomorphological change in rivers and coastal waters. The ability to analyse these processes can lead to graduates working in the area of river engineering, where for example the erosion of sediment from bridge abutments must be controlled. It is also important in ecological modelling where the movement of sediments and entrainment in water can impact on the habitat of stream biota.
The subject will draw on students' existing knowledge of fluid mechanics, systems modelling, statistics, engineering mathematics and geomorphology gained from undergraduate or other preparatory study.
River Hydraulics: revision of basic concepts of steady-state open channel flow and extend this with applications in natural river channels, time dependent behaviour and flood hydraulics
Coastal Hydraulics: basic wave theory and processes including in the surf zone
Sediment Transport and Water Quality: mechanisms and models of particulate and solute transport in rivers and coastal environments
Having completed this subject students are expected to be able to:
Describe flow regimes and what controls the water level in a river
Analyse the flow and backwater profiles of water in natural and constructed channels to predict the channel capacity and flow characteristics such as depth
Analyse the flow water through natural and constructed structures such as chokes, weirs, spillways and energy dissipaters
Design a channel to carry a particular design flow
Describe the characteristics of waves and be able to predict the behaviour of waves in the near-shore environment based on their deep-water characteristics
Calculate the breaking characteristics of waves and their effect on coastal water levels and currents
Interrogate wave recordings for statistics useful in the design of coastal structures and management options
Use tidal constituents to classify the tidal regime at various locations
Recommend coastal management options based on an understanding of waves, tides and near-shore currents
Describe and analyse the processes of sediment erosion, entrainment, transport and deposition in river channels
Predict sediment loads based on channel and sediment characteristics and discriminate between supply and transport limited situations
Predict how channel morphology will change as the result of natural or human impact
Three 30 minute tests, at the end of each four week long module (30%). Associated with Intended Learning Outcomes (ILOs) 1-3, 6-8, 10-12.
Group and online activities for each module equivalent to 500 words for each module and student (30%), each module requiring approximately 13-15 hours of work. Associated with ILOs 1-12.
A 2 hour examination, end of semester (40%). Associated with ILOs 1-3, 5-12.
Readings will be available on-line and as a bound volume available for purchase from the Book Co-op.
This subject is not available as a breadth subject.
Ability to apply knowledge of science and engineering fundamentals
Ability to undertake problem identification, formulation and solution
Ability to utilise a systems approach to complex problems and to design and operational performance
Ability to function effectively as an individual and in teams, as a team leader or manager as well as an effective team member
These modules will be taught using a combination of self-guided readings, tutorial/practice classes (3 hours/weeks) and group work. Readings provide the basic theory and applications, tutorial support learning of this material through sample problems and discussion in practice classes. Students practice the application of this theory to Civil Hydraulics problems in group projects for each module. There are no traditional lectures in this subject.
Readings are provided for this subject and made freely available on-line and for purchase as hard copy at the book room. Readings are taken from the following texts and papers:
