【 摘 要 】

Low-crested structures are designed for some or even severe overtopping. The stability of these structures is sometimes higher than the non-overtopped structures, due to the fact that wave energy can pass over the crest, giving lower wave forces on the armour layer of the seaward slope. Low-crested structures can be classified into three categories: dynamically stable reef breakwaters, statically stable low-crested structures with the crest above swl and statically stable submerged structures. Well described investigations at various institutes (in total about 275 tests) were re-analysed and this has led to practical design formulas and graphs for each of the three classes mentioned above.
