Course overview

AHA believes that a sound knowledge of ‘applied’ hydraulics is essential for a hydrographer’s qualification.   AHA has developed this subject to be practical and relevant to a professional hydrographer’s day to day activities.  

This topic instructs students in hydraulic characteristics that impact site selection in natural streams, channels and pipes.   It provides students with an appreciation of uncertainty of measurement, how to improve accuracy of reported data from a site and the budget implications.  It provides an awareness and knowledge of relevant Australian and ISO standards and National Industry Guidelines.

It covers:

  • Calibrated structures, applying theoretical formulas to various structures and the importance of checking calibrations
  • Site and Survey information required for installing Dopplers and Transit time meters,
  • Relevant standards for various measurement options
  • Theoretical extension to ratings, Manning’s formula and various roughness coefficients. Practical applications of Manning’s
  • Understanding flow conditions – turbulent, laminar, etc
  • Considerations for design, selection and installation of control structures, weirs, flumes
  • Other methods for estimating discharge – tracer dilution, pressure measurement


The syllabus of this course meets and exceeds the requirements of the following unit of competency: NWPHYD001 Apply principles of open channel hydraulics. This unit of competency is a requirement of the Diploma of Water Industry Operations (Hydrography) 50715 .
