The objective of this study was to investigate the effects of shoreline erosion on water clarity in the Chesapeake Bay. To this end, we used the Chesapeake Bay ROMS Estuarine Carbon and Biogeochemistry (ChesROMS-ECB), a biogeochemical model embedded in the Regional Ocean Modeling System (ROMS). Using this model, we simulated a Chesapeake Bay estuary from 2001-2005 with varying magnitudes of sediment inputs from shoreline erosion and varying seabed erodibility conditions. Model results were compared to long-term cruise data from the Chesapeake Bay Program (CBP) (https://datahub.chesapeakebay.net/). These cruise data were used to calibrate certain components of the model and to evaluate model skill for the Reference Run. Three model runs are compared in the associated publication.Specifically, a Reference Run was used which most closely matched observed conditions, while a More Shoreline Erosion model run used double the realistic shoreline sediment inputs with a more erodible seabed, and a Highly Armored Shorelines model run used no shoreline erosion sediment inputs and a more stable seabed. The full results of these model runs are described in the associated publication
