This unit builds on Fluids Mechanics that was covered in Semester 1. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses more on the engineering applications of water and other liquids. Hydraulic topics covered in this unit include practical applications in open channel flow, such as hydraulics structures, flow measurement, river channel behaviour, erosion and sedimentation. These topics would be taught using practical hand-on lab experiments, lab demonstrations and a computer based assignment. The site visit is designed to improve the student's ability to link theory (learnt in the classes) with practical real-world situations.

Topics include:
Pipe flow, boundary layer theory, water hammer; Open channel flow, discharge equations for uniform flow, Specific energy and critical depth, flow transitions and hydraulic jump; Gradually varied flow, classification, water surface profile evaluation; Dimensional analysis, dimensional homogeneity, Rayleigh and Buckingham pi methods, hydraulic model studies; Hydraulic structures, culverts, broad crested and crump weirs; Flow measurements, venturi meter, orifices, sharp crested weir; River hydraulics, river sediment transport and movable bed forms, estimation of sediment loads, reservoir saltation and loss of capacity, river training and control, bank stabilisation and channel maintenance.

Learning Outcomes

On successful completion of this unit, students will be able to:
  1. Apply concepts of hydraulics, complemented with practical laboratory based experiments, site visit and computer labs;  
  2. Apply concepts of open channel flow to practical engineering related problems;  
  3. Use dimensional analysis to develop relationships and also for hydraulic model similitude studies;  
  4. Design hydraulic structures like culverts and weirs;  
  5. Estimate sediment loads carried by rivers.  

Assessment

Assessment type Description Grade
Report Site visit based report - based on self selected site visit in week 9 (Report, photographs, sketches, max word limit of 1500) 10%
Assignment Computer lab based assignment 15%
Practicum One Lab experiment based test 15%
Examination End-of-semester examination 60%
The examination focuses upon the individual student's ability to demonstrate his or her in-depth understanding of specialist bodies of knowledge within the engineering discipline, apply established engineering methods to complex engineering problems, and the fluent application of engineering techniques, tools and resources, as defined in Engineers Australia competencies 1.3, 2.1 and 2.2. In addition, the tasks assess the student on the individual components of Learning Outcomes (LO) (1 to 5) which are not assessed within the report, assignment or practicum. As the examination is the one clear way by which these competencies and LO's can be assessed on an individual basis, students must achieve a minimum mark of 50% in the examination in order to pass the unit. In order to be eligible for a supplementary assessment, students must normally achieve an overall mark between 45-49% for the unit.
