Numerical Model Study of the Tuscarawas River below Dover Dam, Ohio

Abstract : The U.S. Army Corps of Engineers, Huntington District (LRH) has been charged with upgrading Dover Dam to meet hydrologic design standards and address stability issues. The LRH requested that the U. S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (CHL), evaluate the flow conditions in the Tuscarawas River downstream of Dover Dam as part of a safety assurance program. The two-dimensional depth-averaged module of the Adaptive Hydraulics (ADH) finite element flow solver was used to obtain velocity information and water-surface elevations. This report provides water-surface elevations, velocity data, and flow patterns for flows varying from 8,900 cfs to the Probable Maximum Flood of 207,000 cfs. These flows may cause bank erosion downstream of the stilling basin under existing conditions. District engineers will use the information gathered from this study to design bank protection below the dam.
