Scour Protection for Dam No. 7 Monongahela River, Pennsylvania; Hydraulic Model Investigation
Lock and Dam No. 7, Monongahela River is a navigation project located 85 miles from the mouth of the river near the Pennsylvania-West Virginia state line. The dam is an uncontrolled fixed-crest type with a short horizontal spillway apron for energy dissipation. Model tests were conducted on a 1:25-scale section model of the dam, spillway apron, and a section of the river wall of the lock. The purpose of the model study was to determine sizing and configuration of materials necessary to protect the area immediately downstream from the spillway apron from additional scour. A scour protection plan consisting of large grout-filled fabric bags placed downstream of the spillway apron and along the river wall of the lock and a 3-ft-high sloping end sill placed on the existing spillway apron was developed. This plan provided scour protection for all flow conditions anticipated at the project.
