The tidal flow between bridge pillars and through open barriers is a promising source of ocean energy which can be exploited using stream turbines, as proven recently by operational demonstration plants. aim this study to clarify the consequences for power output turbines when placing them in hydraulic structure. To end, experimental measurements turbine wakes are performed, down-scaled mounted...

Low-crested and submerged breakwaters are frequently employed as coastal defence structures. Their efficiency is governed by wave energy dissipation, the transmission coefficient can evaluate this parameter. The current study conducts experimental investigations on both low-crested exposed to different conditions compare their performance with that of emerged breakwaters. provides a comprehensi...
