CIVL6666: Open Channel Flow & Hydraulic Structures (2019 - Semester 1)

Download UoS Outline

Unit: CIVL6666: Open Channel Flow & Hydraulic Structures (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: Civil Engineering
Unit Coordinator/s: Chabchoub, Amin
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Prohibitions: CIVL5666.
Brief Handbook Description: Objectives:

This unit of study will review the principles of uniform flow in open channels. These will be extended into a study of the principles of slowly varying and rapidly varying flow, the calculation of backwater curves and hydraulic jumps. These principles will then be applied to the design of gutters, inlets, culverts and piers, using existing commercially available software packages commonly used in engineering practice.


This Unit will provide students with a strong back ground in open channel flow hydraulics, and the basis for the calculation of stream and hydraulic structure performance. Students will gain experience in the use of currently available commercial software for the design of culverts and other structures.
Assumed Knowledge: Advanced knowledge of fluid mechanics is necessary for this UoS.
Timetable: CIVL6666 Timetable
T&L Activities: 3-hr combined lecture and tutorial per week
