There are now 3 possible online modes for units:
Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.
Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:
- You are a student who is currently offshore and unable to enter Australia.
- You are a student in Australia who is impacted by state or regional border closures.

100% Online Unit. NO campus face-to-face attendance is required to complete this unit. All study requirements are online only. Unit includes some synchronous components, with a requirement for students to participate online at specific times.
Not available for self-enrolment. Restricted to enrolment by students unable to attend campus due to COVID border closures. Students access this mode by contacting their student office through AskUWA. 100% Online Unit.
NO campus face-to-face attendance. All study and assessment requirements are online only. Unit includes some timetabled activities, with a requirement for students to participate online at specific times. In exceptional cases (noted in the Handbook) students may be required to participate in face-to-face laboratory classes when a return to UWA’s Crawley campus becomes possible in order to be awarded a final grade.
No attendance or regular contact is required, and all study requirements are completed either via correspondence and/or online submission.
Regular attendance is not required, but student attends the institution face to face on an agreed schedule for purposes of supervision and/or instruction.
Multiple modes of delivery. Unit includes a mix of online and on-campus study requirements. On campus attendance for some activities is required to complete this unit.
ENVE4403 Fluid Transport, Mixing and Dispersion
- 6 points
Availability Location Mode Semester 1 UWA (Perth) Face to face Semester 1 Online Online timetabled
- The aim of this unit is to gain a quantitative knowledge of the fluid dynamics of both freshwater and marine environments. Topics covered include: physical laws governing fluid motion and exact solutions an introduction to scaling as a means of simplifying complex equations; introduction to turbulence—Reynolds-averaged Navier-Stokes equations, basic statistical descriptions and concept of eddy viscosity, molecular versus turbulent diffusion; mixing in rivers—boundary layers, velocity profiles, hydraulic jumps, transport equation, shear dispersion; mixing in a density-stratified fluid—models of mixing, concept of mixing efficiency and mixing across density interfaces, applications to estuaries, the coastal ocean and lakes; and, turbulent jet, plume and buoyant jet dynamics for wastewater discharge design.
- Students are able to (1) explain the equations that govern the mean flow in environmental systems and derive solutions for flow fields under simplified conditions ; (2) characterise turbulence in environmental flows and its impact on instantaneous flow properties and mixing ; (3) predict the spatial and temporal variability of flows in riverine, coastal and atmospheric systems; (4) distinguish between molecular diffusion, turbulent diffusion and shear dispersion and apply these concepts to quantify mass transport in environmental flows ; (5) describe the extent to which density stratification can control flow and mixing in environmental systems ; and (6) design a laboratory investigation addressing an important problem in environmental fluid mechanics.
- Indicative assessments in this unit are as follows: (1) assignments; (2) laboratories; and (3) a final examination. Further information is available in the unit outline.
For units commencing in May 2022 or later the availability of the supplementary assessment is subject to confirmation.Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.
Except where supplementary assessment is not available in a unit, it will be offered to students in all units who:
- Are in good academic standing overall;
- Have passed over half the units taken in the teaching period concerned, except where they are only enrolled in two or less units in the period;
- Have submitted all assessment items in the unit;
- Have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit; and
- No finding of academic misconduct has been made against them in the unit concerned.
Additionally student may apply for supplementary assessment in any unit which is the final unit required for graduation in there course and where they have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit.

- The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
- All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
- Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
