Abstract The Coastal Modeling System (CMS) numerical model is applied to simulate nearshore planform and beach profile morphology changes during storm wave and water level conditions on a sandy beach stabilized by T-head groins. The numerical model results are compared to measured planform and profile changes from a 1:25 scale, three-dimensional mobile bed physical model study of the beach and Thead groin system. Numerical simulations and comparisons are done at prototype scale. At present, the numerical model calculates well the wave propagation toward the shore and morphology change shoreward of T-head groins. It is evident that there is a need to include the swash zone process, wave asymmetry and undertow to improve the sediment transport calculation in area between the seaward ends of T-head groins.
