This archive contains results of flow and sediment transport simulations of a reach of the Middle Channel of the St. Clair River delta, Michigan using the iRIC modeling system and the Flow and Sediment Transport with Morphologic Evolution of Channels (FASTMECH) solver. Two hydraulic model simulations were used to determine lateral eddy viscosity and roughness settings. A third simulation contains results of the Wilcox-Kenworthy (WK) two-fraction sediment transport model. The WK model was used to simulate the movement of fine grained sediment into coarser immobile substrate. The coarse rock rubble substrate (reefs) constructed in the Middle Channel in 2012 began filling with sand within a year. However, detailed field data to verify the spatial and temporal process of colmation in the Middle Channel reefs are not available. Thus, the sediment transport predictions cannot be explicitly validated but can be compared with field measurements of bedform translation. The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files more manageable in terms of data size.
