Fluid Properties. Hydrostatics. Mass, energy and momentum fluxes. Applications to hydraulic systems. Hydrological processes. Design storms and flows.

Fluid Mechanics and Hydrology is the first compulsory course on fluid mechanics in the
undergraduate curriculum for civil and natural resources engineering students.

The course is split into two self-contained sections that reflect a general philosophy of the course.
The course aims to provide undergraduate civil and natural resources engineers with an
understanding of, and an ability to solve, standard hydraulics problems that a practising hydraulics
engineer might encounter. This includes the determination of hydrostatic forces on structures, the
modelling of single pipe systems and the determination of surface runoff from storm events. At
the same time the course aims to provide you with an understanding of the fluid properties and
fluid flow principles that underpin all types of fluid motion. The conservation laws of mass, energy
and momentum will be the foundation upon which more complex behaviour such as shockwaves
in pipes, effluent dispersion and gravity currents are built. Fluid mechanics and hydraulics courses
in the third professional year, and at graduate level, extend on these principles, providing students
with experience and problem solving ability in a range of typical applications.

Learning Outcomes

  • At the conclusion of this course

  • You (the students) have an appreciation of the role of fluid mechanics and hydrology in Civil
    and Natural Resources Engineering.
  • You understand fluids properties and their importance to modelling fluid behaviour.
  • You can model (and hence predict) the impact of stationary fluids on associated boundaries.
    You can extend these concepts to deal with issues of object stability under submerged and
    floating conditions, and in addition fluid bodies subject to accelerations.
  • You can qualitatively describe fluid flow phenomena in such a way that assumptions, which
    aid the modelling of flow behaviour, become obvious.
  • You can apply the conservation laws (mass, momentum and energy) to model fluid flows,
    making effective use of control volumes and the integral forms of these laws.
  • You can employ the conservations laws to model and design single pipeline systems and
    understand how to use energy concepts in the selection of pumps and turbines. You can
    demonstrate this knowledge in a real laboratory pipe system.
  • You can use historical flood flow data and/or rainfall data to estimate the design flood flow
    for a catchment of known physical properties.
  • Most importantly you can apply the concepts above to model a broad range of relatively
    simple hydraulic and hydrological problems (including those that you may not have seen

    Each of these learning objectives will contribute to the Employable, innovative, and enterprising
    graduate attribute defined by UC and the Engineering knowledge (WA1) graduate attribute defined
    by the Washington Accord.

The assessment for this paper will comprise largely of regular tutorial submissions, a laboratory
report, a mid-semester test and the final exam. The coverage of the test as well as the timing of the test will be provided within term 3.

The internal assessment for the course has two aims. The first is clearly for us to obtain information about how well you understand the material being taught. Such assessment is known as summative assessment. However the assessment also plays a second more important role, in that it provides you with feedback on your progress, and highlights things that you haven’t completely understood.

This is called formative assessment. Make sure you do all internal assessments for the course
conscientiously and reflect on your work after it has been marked.

Test and Exam: The test and exam are worth 80% of the final grade. The test will consist of a few
problems and student solutions will be provided after the test session. These problems will be
marked and returned to the students within approximately 3 weeks. The test will be conducted
under conditions normal for an examination.

The solutions prepared by the students must be legible and well presented. Poorly presented
material will be given 0 marks. If you suspect there is an error in the test or exam, you must make a reasonable assumption and proceed with the question. If there was indeed an error, you will not be penalised. Applications for aegrotats or special consideration based on errors in the test/exam questions will not be accepted.

Tutorials: Weekly tutorial submissions provide an opportunity for students to implement the ideas
presented during lectures, with support from staff and tutors. They normally take the form of a
problems class, where one or two questions are set and solutions are collected at the end of the
tutorial session. Each tutorial is worth two marks. Students who are unable to complete the
question, but are able to make a reasonable attempt at the question(s) will receive one mark for
the tutorial session. The tutorials also provide an important opportunity for students to discuss
difficulties associated with the material presented in the lectures directly with the lecturer.

As with the test, the solutions prepared by students must be legible and well presented; poorly
presented material will be given 0 marks.

1.         You cannot pass this course unless you achieve a mark of at least 40% in each of the mid-semester test and the final exam. A student who scored 35-40% in either the test or exam, but performs very well in the other, may be eligible for a pass in the course.
2.         All  assignments  must  be  submitted  by  the  due  date.  Late  submissions  will  not  be accepted. If a student is unable to complete and submit an assignment by the deadline due to personal circumstances beyond their control they should discuss this with the lecturer involved as soon as possible.
3.         All  assignments  can  be  done  individually  or  in  pairs.  If  done  in  pairs  a  single submission  for  marking  is  required  and  both  students  receive  the  same  mark.  It  is important that both students play an equal role in completing the assessment as the internal assessment is designed to prepare you for the formal assessments.
4.         All laboratory reports must be done individually."
