CIVIL 302 : Hydrology and Open Channel Flow

Engineering

2025 Semester Two (1255) (15 POINTS)

Course Prescription

Engineering hydrology: Hydrologic processes, analysis of rainfall-runoff relationships, statistical analysis of hydrological data, groundwater flow. Open channel flow: energy and momentum, uniform flow and flow resistance, critical flow, specific energy and flow force, backwater analysis, channel transitions. Environmental and sustainability considerations.

Course Overview

This paper covers the study, in an engineering context, of the occurrence and management of atmosphere, surface and subsurface waters, and the hydraulics of open channels. It is intended to give students the background and tools necessary to understand, analyse and design components of hydrologic systems, and the tools necessary to analyse and design artificial and natural channels.
  
The course covers the following topics:
  • Open Channel Flow: types of flow; uniform flow (continuity, energy); flow resistance (Manning equation); specific energy (critical depth for 2D and arbitrary shaped channels); momentum relation (hydraulic jump, energy loss); gradually varied flow (flow profiles, solution using step method and direct integration).
  • Hydrologic processes and Measurements: Hydrologic Cycle; Precipitation; Evaporation and Transpiration; Infiltration; Rainfall; Streamflow
  •  Analysis of Rainfall-runoff relationships: Rational Method, Unit Hydrograph Theory
  • Statistical analysis of hydrological data: Data Selection; Frequency Analyses and Statistical Methods
  • Hydrologic Design for Surface Waters: Design Storms; Risk Analysis; TP108

Quizzes

Students must sit the exam to pass the course. Otherwise, a DNS (did not sit) result will be returned. A passing mark is 50% or higher, according to University policy.

You must achieve at least 40% in the final exam and at least 40% in the combined coursework (Test + Labs + Quizzes) to pass the course, otherwise a grade of D+ is awarded.

Late submissions will not be accepted/allowed for the exam and test. It is possible to submit late for the other assessments, and the late submission penalty schedule will be included in the submission forms on Canvas.

Teaching & Learning Methods

Instructors will often combine lectures and tutorials in a single timeslot, with formal lecture material (recorded) and informal helpdesk/tutorial sessions (not-recorded to encourage class participation). 

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, in a typical week you can expect 3 hours of lectures/tutorials/help desks, and 7 hours of self-study (reading and thinking about content, working on assessments including pre-lab reading, and test preparation ) and labs.

Delivery Mode

Campus Experience

Attendance on campus is required at scheduled activities (test, labs) to be eligible to receive credit for those components of the course. No attendance at a lab will lead to zero marks for that lab, with no lab re-sits.

Lectures will be available as recordings. Other learning activities including tutorials/labs/helpdesks will not be available as recordings.

The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

All required course material will be provided on Canvas. The following texts (amongst others) have good coverage of course material for further reading if desired:
• “Hydraulics in Civil and Environmental Engineering.” Chadwick and Morfett (3rd edition, published by E & FN Spon).
• “Fluid Mechanics.” White, F.M. (7th edition, published by McGraw Hill).
• “Applied Hydrology.” V.T. Chow, D.R. Maidment, L.W. Mays, McGraw-Hill, 1988.
• “Waters of New Zealand.” M.P Mosley (ed.), New Zealand Hydrological Society, 1992.
• “Engineering Hydrology.” E.M. Wilson (4th edition), Macmillan, 1990+.
• “Hydrology in Practice.” E.Shaw (2nd edition), Chapman and Hall, 1988+.

Health & Safety

There are robust measures to deal with health and safety issues related to lab related activities. Students are expected to adhere to the guidelines outlined in the Health and Safety section of the Engineering Undergraduate Handbook. Students need to be aware of risks associated with possible spillage of water on the laboratory floor, rendering the floor slippery.

Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

- Lab structure
- Test schedule alignment to course content.

Other Information

Each laboratory session is of two hours duration. Examples of topics covered include:
  • Hydraulic jump
  • Rainfall–runoff relationships
  • Rating curve
  • Augmented reality  sandbox

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework, tests and examinations as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning
