| 摘要： | Studies were performed using the existing 1:120 physical navigation model of the R.C. Byrd Locks and Dam. The model study was performed primarily to determine navigation conditions that would be associated with the construction of proposed dikes immediately downstream of the dam. These dikes would be built as environmental mitigation habitat to compensate for areas that are to be taken for the Ohio River Main Stem Study project. The proposed dikes could not adversely affect navigation conditions in the lower lock approaches. The model was also used to indicate whether the dikes would affect sediment shoaling in the lock approaches. This was done by the use of a plastic tracer bead material. The model was also used to obtain current velocities around the proposed dikes. These velocities were then used to determine the stone sizing and gradation required for construction of these dikes, which is presented in Appendix A. |
