We will consider particle image velocimetry observations that show, at times, significant temporal evolution of seafloor roughness  (e.g., Ripple geometry). A series of medium and large scale laboratory observations taken outside the surf zone in nearshore forcing environments have been obtained over the past 10 years. Ripple geometries are shown to be generally anorbital in nature with amplitudes and steepness that are modulated by the wave forcing.
