An analysis of the interactions between wave-induced velocities and seagrass meadows has been conducted based on large-scale CIEM wave flume data. Incident irregular trains act an initial 1:15 sand beach profile with measurement stations from offshore a surrogate meadow until outer breaking zone, after crossing meadow. The considers variability peaks velocities, together their skewness asymmetry, to determine effects near bed sediment transport. Velocity was characterized by standard deviation, greatest changes were found in area right behind In this negative peak decreased up 20.3%, positive increased 11.7%. For more onshore positions, similarly most studied stations. A progressive increase as waves passed through meadow, slight decrease observed associated effect. Moving shoreward along profile, values asymmetry progressively relative position main sandbar. megaripple-like bedforms appeared earlier when present due higher skewness, showing belated development layout without further proximity breaker To assess transport capacity submerged SANTOSS formula applied, that front there capacity, whereas could be reduced 41.3%. addition, able produce suitable estimate across although it not properly volumes generated profile.
