Laboratory and numerical experiments on stem waves due to monochromatic waves along a vertical wall

<p>In this study, both laboratory and numerical experiments are conducted to investigate stem waves propagating along a vertical wall developed by the incidence of monochromatic waves. The results show the following features: for small-amplitude waves, the wave heights along the wall show...
