Description

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

- Describe fluids properties and their importance in modelling fluid behaviour (Washington Accord WA1), (UC EIE)

- Model (and hence predict) the impact of stationary fluids on associated boundaries, and extend these concepts to deal with issues of object stability (submerged and floating), and fluid bodies subject to accelerations (Washington Accord WA1), (UC EIE)

- 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 (Washington Accord WA1), (UC EIE)

- Employ the conservations laws to model single pipeline systems and understand how to use energy concepts in the selection of pumps and turbines (Washington Accord WA1), (UC EIE)

- Make use of historical flood flow data and/or rainfall data to estimate the design flood flow for a catchment of known physical properties  (Washington Accord WA1), (UC EIE)

- 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)  (Washington Accord WA1), (UC EIE)

The assessment for this paper will comprise largely of regular tutorial submissions, a laboratory report, a project, a mid-semester test and a 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.

Special Considerations

Any student who has been impaired by significant exceptional and/or unforeseeable circumstances that have prevented them from completing any major assessment items, or that have impaired their performance such that the results are not representative of their true level of mastery of the course material, may apply for special consideration through the formal university process. The applicability and academic remedy/action associated with the special consideration process is listed for each assessment item below. Please refer to the University Special Consideration Regulations and Special Consideration Policies and Procedures documents for more information on the acceptable grounds for special consideration and the application process.

Special Consideration for Assignments
An extension will be granted for evidence-supported requests. Extensions will typically be for up to one week, but the duration will be considered on a case-by-case basis. Students seeking an extension must contact the course coordinator as soon as possible with evidence of their situation, and preferably before the due date.

Special Consideration for Midterm Tests
Students will be offered an equivalent alternative test that will replace their original test mark.

Special Consideration for Final Exam
Students will be offered an equivalent alternative exam that will replace their original exam mark.

Note: All communication associated with the arrangement of equivalent alternative tests/exams will be conducted using official UC email accounts.. Students will have a clearly specified amount of time to respond to the offer to sit the alternative assessment. If the offer is declined or no response is received in the specified time frame, the original assessment mark will be used to compute the course grade.

Textbooks / Resources

This course is self-contained and all necessary material will be provided through the lectures and Learn.
