Description

Fluid Properties. Hydrostatics. Mass, energy and momentum fluxes. Applications to hydraulic systems. Water resources and global climates. Stream and groundwater flow.

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 Content

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 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. A number of problem set questions are also provided (with solutions released during the course) to help you understand the material.

It is important to note that the tutorial sessions are designed to be introductions into the topics and your expertise in the material must be gained through repeated practice by working through the problem set questions. Simply doing the tutorials each week will not provide you sufficient knowledge to pass this course.

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 (hours)/stream          Lecturer
Introduction 1                                  Davidson
Fluid Properties 7                                  Davidson
Fluid Statics 12                                  Davidson
Kinematics &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.

Laboratory Exemptions

Students repeating this course may see the instructor to apply for an exemption from the laboratory experiments. However, we suggest that you redo the laboratory to strengthen your understanding of the area.

Lecturers

Craig McConnochie , Elizabeth North , Tonny de Vries and Mark Davidson

Postgraduate and senior undergraduate students will also assist during the laboratory and tutorial sessions.

Assessment

Assessment Due Date Percentage 
exam 20%
Pipeline laboratory 5%
Pipeline Design Test (online) 20%
Hydrology project 5%
test 40%
Tutorials submission 10%


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, online test and the final exam. Withdraws from the course will not be supported by the department subsequent to a test failure.

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 hydrology assignment 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
