Experimental Study of Microplastic Particle Transport Around Sea Gravel in Waves Plus Current Conditions
Year: 2025
Type: article
Abstract: Microplastics (MPs) are considered to be potentially the most harmful plastic fraction in the ocean (Law and Thompson, 2014). Guler et al. (2022) examined the transport of non-buoyant MP particles beneath irregular breaking waves over a live sediment bed in extended test durations. They identified that accumulation hotspots were largely governed by the particle Dean number. Larsen et al. (2023) developed an approach based on wave-induced transport velocity to predict the onshore transport of buoyant MP particles across a coastal profile. In the present study, we further this research to experimentally investigate the potential retention of MPs under the effects of combined (non-breaking) irregular waves and current in coastal waters by gravel patches having various coverage density.
