A two-layer k-omega model was used to predict boundary layer properties under a solitary wave. The prediction for the velocity profile shows excellent agreement with the experimental data in initial part of the acceleration phase. but close to free-stream crest velocity poor agreement was observed. The boundary layer thickness was also overestimated by the model. The bed shear stress showed good agreement in the initial part of the acceleration phase but the peak value was overestimated. Further study is required to explore the capabilities of other two-equation models and more experimental data should be utilized for that purpose.
