Planform Effects on Tidal Flushing of Marinas
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 110, Issue 2
Abstract
Effects of various geometry parameters on tidal flushing and internal circulation in small‐boat basins (marinas) of rectangular planform were determined in physical hydraulic models by means of a photographic technique incorporating the use of a photodensitometer. The schematic model marinas tested were scaled to have surface areas, water depths, and tide ranges comparable to “prototype” marinas in the Pacific Northwest: Results are presented in terms of spatial average tidal flushing (exchange) coefficients for each configuration tested, and by contour drawings of equal local per‐cycle exchange coefficients for a number of configurations, all at the same tide range. Emphasis is placed on planform geometry and aspect ratio, those variables over which designers may have most latitude in designing a marina for a specific site. Effects of basin length to width ratio are delineated for basins with typical single asymmetric entrances.
