Book excerpt: This report presents results of model studies on Missouri River boat marina entrance configurations which were conducted at Mead Hydraulic Lab. Small boat marinas along alluvial rivers are constantly plagued by the deposition of sediment at marina entrances and, subsequently, within the marina themselves. Dredging of this accumulated sediment is usually required at regular intervals. Recognizing that no system of entrance structures or alignment will totally prevent the deposition of sediment, the objective of this investigation was to determine how to minimize the deposition of sediment in a marina entrance. This investigation evaluated the Sioux City type marina entrance which incorporated recommendations from the Bucharest Report. Also studied were the UNL (Univ. of Nebraska at Lincoln) egg-shaped basin and other successful marina entrances on the Missouri River.
