If this unit does not have an online alternative, then students who are presently unable to enter Western Australia and whose studies would be delayed by an inability to complete this unit, should contact the unit coordinator (details given on this page) to ascertain, on an individual case-by-case basis, if alternate arrangements can be made to support their study in this unit.

Semester 1UWA (Perth)Face to face Predominantly face-to-face. On campus attendance required to complete this unit. May have accompanying resources online.
Semester 1UWA (Perth)Online timetabled 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.
Content
This unit presents an introduction to geology and geological processes as they affect civil, resource and environmental engineering projects. Topics include weathering; erosion; minerals, rock and soil types; the rock cycle, rock-forming processes and soil-forming processes. All topics are explained using well-illustrated local and international examples. Full use is made of available video footage and demonstration models and students gain hands-on experience of various soil and rock types. The unit then deals with concepts of effective stress; soil compression and consolidation; seepage; and the strength and deformation properties of soil. The underlying framework is that of critical state soil mechanics which links the strength and stiffness of soil to the density and effective stress level. In-class practice sessions are an essential component of the teaching of the unit to ensure students gain supervised experience in the application of effective stress and critical state principles. Students observe and report on laboratory experiments designed to supplement understanding gained at lectures on the strength and compressibility of soils.
Outcomes
Students are able to (1) write concise technical reports; (2) apply critical thinking to assignments and laboratory work; (3) use interpersonal skills when working in teams; (4) identify the role of geotechnical engineering in the civil engineering design process; (5) apply geotechnical design principles in civil engineering design; (6) identify soil properties of compressibility and strength for soil foundation design; (7) perform soil laboratory tests on soil properties for foundation design; (8) assess the pros and cons of soil laboratory testing and in situ soil field tests; and (9) work in teams.
Assessment
Indicative assessments in this unit are as follows: (1) lab quiz and active participation; (2) laboratory reports; and (3) module tests. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • 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. Reading lists and essential textbooks are subject to change each semester. 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. Copies of textbooks and other readings will be made available for students to access from the Library, online wherever possible as well as in print.
