Study on wave-induced setup over fringing reefs in the presence of a reef crest

Large eddy simulation modeling of tsunami-like solitary wave processes over fringing reefs

“…As for the effect of reefcrest width (Fig. 12d), although the presence of a reef crest is reported to be an important factor affecting the wind wave transformation over fringing reefs (e.g., Yao et al, 2017), it seems to have little impact on the solitary wave run-up under both h r ; a slight decline of R could only be found under crest widths larger than 0.4. This is because the solitary wave is very long compared to the reef-crest width; thus most of its energy could transmit over the narrow reef crest.…”

Experimental investigation of monochromatic wave transformation characteristics over the coral reefs

“…虽然本试验地形坡度与Gourlay [12] 相同, 但是斜坡 前水深差别很大, 本实验礁体前水深大于1.8 m, 而 Gourlay [12] 礁体前最大水深仅为0.42 m, 其他研究的试 Figure 7 (Color online) The relationship between the maximum wave set-up and the various wave conditions.
