Open channel flow; pipe networks; scale and dimensional analysis; surface and ground water.

Hydraulics and Applied Hydrology is the second, and final, compulsory course on fluid mechanics in the undergraduate curriculum for civil and natural resources engineering students. It follows on from ENCN242, Fluid Mechanics and Hydrology, in second year.

The course is split into a series of self-contained topics that fall under the broad category of water resource engineering.

The first half of the course focuses on knowledge and skills a practising civil or natural resources engineer will require in practice. This includes the analysis of steady open channel flow and the design and analysis of pipe network systems.

In the second half of the course, we extend these focused applications into a diverse portfolio of topics that a practicing water resources engineer could encounter. We will introduce you to the engineering of hydrological systems, including groundwater wells, surface water management, and the mathematical foundations of more sophisticated fluid systems.

These applications are an introduction towards more advanced topics that can be studied in fourth year and beyond. Examples of these later topics include modelling groundwater in underground aquifers (ENCN442), turbulence (ENCN441) and water hammer in pipes (ENCN446).

Learning Outcomes

The learning objectives for this course are given below. It is expected that you will achieve some level of understanding of the learning outcomes and your grade will be based on your demonstrated level of understanding.

Each learning objective maps to one of the attributes in the Washington Accord: an international agreement that stipulates the key learning outcomes for professional degrees in a number of jurisdictions around the world, including New Zealand. You can find the full list of these attributes at the website  http://www.ieagreements.org/accords/washington/

- Analyse transitions, hydraulic jumps, uniform flow and gradually varied flow in steady open channel hydraulics. (Washington Accord WA1)

- Analyse and design simple pipe networks. (Washington Accord WA1)

- Explain the key hydrological processes that are important from an engineering perspective and apply models to quantify these processes. (Washington Accord WA1)

- Apply principles of groundwater well design including material selection, testing and protection procedures. (Washington Accord WA1)

- Analyse problems in fluid mechanics using tools of dimensional and scale analysis. (Washington Accord WA1)

Assessment Due Date Percentage 
final exam 40%
Lab work 2%
Mid term test 40%
Tutorials 18%

The assessment for this paper in comprises weekly tutorials, lab calculations, a mid-semester test, and a final exam.

Invigilated assessment
All of the material on learning objectives 1 and 2 will be examined in the midterm test and this will be worth 40% of your final grade. All of the material on learning objectives 3, 4 and 5 will be examined in the final exam and this will be worth 40% of your final grade.

The total invigilated assessment is 80%.

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.

2. For students that achieve less than 40% in the mid-semester test, a resit will be offered. If a student achieves 40% or higher in the resit, they will be able to pass the course. In this case a mark of 40% in the mid-semester test will be used in the calculation of a final grade, regardless of the actual mark in the resit.

3. All assignments must be submitted by the due date. Late submissions will not be accepted. If you are unable to complete and submit an assignment by the deadline due to personal circumstances beyond your control, you should discuss this with the lecturer involved as soon as possible.

4. In the case of an emergency that affects the whole course, the Course Coordinator, in consultation with the Dean, may change the nature, weighting and timing of assessments, e.g. tests and examination may be replaced with assignments of the same weight or different weight at a different time and/or date (which, under certain circumstances, may be outside the prescribed course dates). The ‘Special Consideration’ process will also be used for unforeseen circumstances that adversely affect the academic performance of students individually. The usual grounds for this are described in the UC policy ‘Special Consideration Procedures and Guidelines’, and personal circumstances due to a wider emergency event may also qualify.

Additional Course Outline Information


Due to the numbers enrolled in this course, two lecture/tutorial streams will run in parallel. Both lecture/tutorial streams will cover the same material at the same pace and will have the same lecturers. Please ensure that you attend the lecture/tutorial stream to which you have been allocated.

A total of 24 laboratory sessions have been timetabled and you will have been allocated to one of these laboratory sessions. Please attend the session to which you have been allocated. If a conflict arises that means that you cannot attend your allocated laboratory session, please contact the course coordinator as soon as possible in order to arrange an alternative session. Remember, you must attend and complete the laboratory in order to sit the midterm test.
