Physical Modelling in Hydraulics
Last Updated: 2026-02-05 15:42:16
Abstract
This lecture focuses on physical hydraulic modelling, measurements and data analysis techniques. The advantages and limitations of the similitude laws and measurement techniques are presented with examples. The knowledge will be applied by the students in individual group work using a hydraulic model at VAW. This lecture is recommend for students with interest in an experimental MSc-thesis at VAW.
Objective
To deepen knowledge on possibilities and limitations of experimental modelling in hydraulic engineering and relevant measurement techniques, and to advance in data analysis i.e. time and frequency domains, error analysis and data interpretation.
Content
Fluid properties and basic equations Similitude and dimensional analysis Scaling laws and upscaling limits Modelling techniques and how to build physical scale models Sediment transport modelling (gravel bed rivers) & Sediment monitoring techniques Measurement techniques: Laser Doppler Anemometry (LDA), Particle Image Velocimetry (PIV), Particle Tracking Velocimetry (PTV), Acoustic Doppler Velocimetry (ADV) and Acoustic Doppler Current Profiler (ADCP) Video-metry and fibre optical instruments Data analysis including curve fitting and error analysis Laboratory visit including introduction to experimental facilities Individual laboratory work in groups (measurement, data analysis and interpretation)
