Below the graphic, movement of plastics is depicted given different tidal scenarios (ebb and flood tides), where flood tides may move the microplastic particles from the river channel to the SAV beds and marshes. Ebb tides may move particles back towards the river channel. This graphic also illustrates the deposition and resuspension of particles in these various habitats.

Project Abstract

The University of Maryland Center for Environmental Science (UMCES) will use a wind-generated wave model (Delft3D-SWAN) to examine the role marshes and submerged aquatic vegetation (SAV) beds have in determining the fate of plastic debris as it is transported down the Choptank River. The expected outcome is the development of a budget of plastic debris input and retention in the Choptank River. Field data collections will inform both the model and plastic budget based on plastic volume across the river channel, SAV beds, river bank/ridge, and marsh platform. Specifically, researchers will characterize the size and abundance of debris in the water and sediments of the Choptank River basin, and will compare plastic deposition and degradation rates between open water and vegetated habitats. This study will examine an aspect of riverine transport (and fate) that has not yet been explored in great detail. Additionally, UMCES researchers will establish a Management Transfer Advisory Group that will be tasked with providing input on project design, model scenarios, and dissemination of research results.

Conceptual model of the plastic budget in the Choptank River. Blue arrows show deposition, green arrows show resuspension, and red and black arrows show transport due to tides and overall. Sampling for this study will occur at a number of locations and at flow conditions across the different habitat regions depicted here. (Graphic credit: W.
