TLDR
In this article, the wave-induced upward seepage under the wave troughs may weaken the buoyant unit weight of the surrounding sand, which brings the sand-bed more susceptible to scouring.About:

Scour effects on p-y curves for shallowly embedded piles in sand
TL;DR: In this paper, a series of centrifuge model tests with various scour profiles were conducted at a scale of 1:250 to investigate the effects of both local and general scour on the response of a laterally loaded pile.

Combined wave and current interaction with a rough bottom
TL;DR: In this paper, an analytical theory is presented to describe the combined motion of waves and currents in the vicinity of a rough bottom and the associated boundary shear stress, and the resulting linearized governing equations are solved for the wave and current kinematics both inside and outside the wave boundary layer region.

Time scale for local scour at bridge piers
Bruce W. Melville,Bruce W. Melville,Bruce W. Melville,Yee-Meng Chiew,Yee-Meng Chiew,Yee-Meng Chiew +5 more
TL;DR: In this article, the authors studied the influence of flow duration on the depth of local scour at bridge piers in uniform sand beds and showed that the scour depth after 10% of the time to equilibrium is between about 50% and 80% of equilibrium scour depths, depending on the approach flow velocity.
