Overview

The emphasis of this course is the application of hydraulic theory to the solution of problems commonly encountered in engineering hydraulics and to the design of hydraulic systems and structures. The basic concepts of the conservation of mass, momentum and energy (introduced in Hydraulics I) are reviewed, extended and applied to a variety of hydraulic systems. New material on unsteady pipeline and open channel flows, loose boundary hydraulics and coastal hydraulics is presented and applied. Students are practised in the design and analysis of open channel, pipeline and pumping systems and a wide range of hydraulic structures.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. evaluate and apply the equations available for the description of open channel and pipe flow; 1. derive and apply the equations governing rapidly varied unsteady channel flow including surge waves;
  2. solve the equations governing both steady and unsteady gradually varied channel flow and apply them to the solution of practical flow problems including: backwater profiles; runoff on a plane surface and routing of a stream hydrograph; design erodible and vegetative lined channels;
  3. solve simple pipe networks using an appropriate method;
  4. apply rigid column theory to unsteady pipeline flow to analyse mass oscillations in pipelines and calculate maximum allowable rates for valve opening and closure;
  5. apply rigid and elastic water hammer theory to pipeline systems;
  6. design a range of hydraulic structures including: fixed and movable crest weirs; gated control structures; pipe conveyance structures; spillways and energy dissipation structure; critical flow measuring flumes; gulley control structures ; weir and culvert type structures using the minimum specific energy concept;
  7. undertake a dimensional analysis of a physical system incorporating many variables; design a model of a hydraulic system using Reynolds or Froude scaling.

Student workload expectations

To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
