Abstract : A scale model study was conducted to see if a proposed widening of the entrance channel at Depoe Bay, Oregon would allow appreciably more wave energy to enter the harbor area. A linear, undistorted Froude Scale of 1 to 120 was used. The model was constructed of mortar in a wave tank 72 feet long and 1.5 feet wide, with a stillwater depth of about 1.0 foot in the deeper area beyond the harbor entrance. Ponding in the model bay due to wave action was noted, and in extreme cases exceeded the equivalent of 5 feet prototype. The wave height transmission coefficient for waves traveling from offshore through the channel and into the bay ranged from greater than 1.0 for long waves to less than 0.1 for short waves. (Author)
