Abstract:

The Military Ocean Terminal, Sunny Point (MOTSU), is located on the Cape Fear River, approximately 18 miles downriver from Wilmington, North Carolina. The facility has experienced significant shoaling in excess of 1. 9 million cubic yards per year since it was constructed in 1953. Faced with a disposal area shortage and the fact that spring freshets can cause significant shoaling within a few weeks, MOTSU embarked on a shoaling study which included the use of physical and numerical models. A program was developed which includes: 1. Modifying the geometry of the terminal's channels to improve flow conditions; 2. The use of hydraulic jets to maintain berth areas; and 3. A redefinition of non-navigable bottom based on sediment density.
