The objectives of the SWOLS modeling project were to 1) assess the interacting effects of tides, reefs/breakwaters, waves, sediment resuspension, and oyster filtration on seagrass habitat using a modeling approach, and 2) develop a tool that can be used to help inform seagrass and oyster restoration efforts.

The SWOLS model is based on NearCoM and is composed of a quasi-3D circulation model (SHORECIRC), a wave model (REF/DIF), a sediment transport model, and sub-models for oyster filtration and seagrass growth:

This research was funded by the NOAA Maryland Sea Grant College Program. Additional support was provided by the Horn Point Summer Teacher Fellowship Program, the National Science Foundation Research Experiences for Undergraduates Program, and the Keith Campbell Foundation for the Environment.
