Learning Outcomes

  • In completing this course we (the students and staff involved) aim to have achieved the following:

  • 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 before).

Timetable Note

Course Structure

This is a lecture and tutorial-based course scheduled for the second semester. Sections of this course will be presented in different formats. The latter part of the course will be presented in a traditional lecture/tutorial format with 4 hours of lectures per week supported by additional tutorial sessions. However, the first part of the course will be taught using an alternative format, where a summary lecture is given at the beginning of the week and this is then followed by a series of 3 tutorials (with groups of 60 or so students). Detailed explanations of the material presented in the summary lecture are available on Learn and students are expected to review these in preparation for the tutorials. In addition, laboratory sessions will be run during the afternoons of the fourth term. These laboratories are designed to provide you with practical experience of fluid flows that will be discussed during the lectures.

The topics to be covered in lectures, together with the time and lecturer allocated to each, are listed in the following table.

Topic                                     Time        Lecturer

Introduction                     1            Lee
Fluid Properties                     7            Lee
Fluid Statics & kinematics     12            Davidson
Conservation Laws           12            Lee
Pipe Systems                     6            Lee
Hydrology                            10     De Vries

A detailed laboratory timetable will be provided.  Attendance at laboratories is compulsory. If you cannot attend your timetabled laboratory class you must arrange to swap with somebody in another session of the same laboratory.

Assessment Due Date Percentage 
Hydrology assignment 5%
final exam 40%
Labs (fluid mech section) 5%
test 40%
Tutorials (fluid mech section) 10%

Test and Exam: The test and exam are each worth 40% 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.

You cannot pass this course unless you achieve a mark of at least 40% in the test and exam. A student who narrowly fails to achieve 40% in one of these assessments, but who performs very well in the other, may be eligible for a pass in the course.

The solutions prepared by the students must be legible and well presented. Poorly presented material will be given 0 marks.

Tutorials: Tutorials will be conducted on a regular basis during the term. These 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. Students who make a reasonable attempt at the question(s) receive full marks for the tutorial session. The tutorials also provide an opportunity for students to discuss other difficulties associated with the material presented in the lectures.

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