HYDROLOGIC AND HYDRAULIC MODELING OF A COASTAL WATERSHED TO ASSESS THE IMPACT OF DAM REMOVAL ON GEOMORPHOLOGY AND FISH HABITAT

The Ballville Dam extends across the Sandusky River (Ohio) 20 kilometers upstream of Lake Erie. The benefit of the dam was as a water supply but its impact on river morphology and fish migration are important issues. A quantitative assessment of the dam's impact to the river morphology and ecosystem requires analysis of both the physical and biological environments. This assessment would provide researchers, dam owners, and engineers with valuable information to make a management decision on the future of the dam. As part of this assessment, a model of the physical environment of the Sandusky River in the area of Ballville Dam was developed using the 1-D hydrodynamic program MIKE11. Using existing hydrologic and hydraulic data, the model simulates historical flows on the Sandusky River combined with different scenarios for dam operation and removal. The information generated by the model provides data on potential geomorphologic changes and output of physical variables used for a coupled ecosystem model.
