{ "DOI": "10.1021/acs.est.3c02027", "abstract": "<p>This researchnewly shows that, when suitably generalized,the Shields diagram (as commonly used for sediments) can predict incipientmotion thresholds for both native sediments and foreign (microplastic)particles alike.</p>\n<p>Incipient motion conditions for 57 regular (spheres,cylinders,disks, square plates, cubes, square prisms, rectangular prisms, tetrahedrons,and fibers) and eight irregular microplastic particle groups, havingvarious sizes and densities, are investigated in a circular flume.The present data set is combined with additional data from the literatureand systematically analyzed. A new framework is developed for predictingincipient motion conditions for foreign particles, accounting forvariations in static friction, hydraulic roughness, and hiding-exposureeffects. Via this framework, incipient motion conditions for microplasticparticles lying on a sediment bed are, for the first time, reconciledwith the classical Shields diagram.</p>", "author": [ { "family": "Goral", "given": " Koray Deniz" }, { "family": "Guler", "given": " Hasan Gokhan" }, { "family": "Larsen", "given": " Bjarke Eltard" }, { "family": "Carstensen", "given": " Stefan" }, { "family": "Christensen", "given": " Erik Damgaard" }, { "family": "Kerpen", "given": " Nils B.
