Information on the offshore wave climate is often available from either buoys or national wave models. As waves travel into the nearshore or any shallower region (for example over sandbanks) they undergo several transformations including depth-induced breaking, shoaling and refraction. SWAN (Simulating Waves Near Shore) is a phase averaged, third-generation wave model ideally suited for modelling waves in coastal regions. SWAN was developed at Delft University of Technology and is freely available.
This one day course provides an overview of wave transformation theory and explores the representation of waves within numerical models. Through hands-on tutorials you will be shown how to set-up and run SWAN, including pre-processing data to create model meshes and post-processing to view results, using the open source Blue Kenue software.
This course is aimed at anyone who is going to perform SWAN modelling or use SWAN modelling results in their job, for example coastal engineers and scientists in local government and consultancies. No previous experience of running
computational wave models is required.
By the end of this course you will:
• Gain an understanding of wave generation and transformation processes
• Be able to generate model grids
• Understand the SWAN model settings, and corresponding steering file keywords
• Be able to run SWAN
• Understand model calibration and validation process
• Be able to analyse and plot results using Blue Kenue
• Have the ability to critically review the key elements of a SWAN model

Fay is a senior coastal flood analyst working within the JBA Coastal Modelling and Forecasting Team. She has in depth knowledge of the mathematical theory behind numerical models of waves and free surface flows and has worked across government, private and academic sectors delivering wave modelling, flood inundation and sediment transport studies. Fay has applied the theoretical statistical knowledge from her mathematics degree to perform statistical assessments of extreme values including using the Heffernan and Tawn multi-variate technique to estimate extreme water levels, waves and winds. She has experience of modelling shallow water wave transformations using the SWAN and TOMAWAC wave models for multiple projects around the UK and has experience of developing bespoke forecasting systems.
