Wave-driven flow over the reef flat plays an essential role in shaping the morphology of coral reefs, whose biological, ecological and geological processes are significantly affected by the water exchange between the open sea and the reef flat. In this study, detailed flow measurements are conducted to investigate the vertical flow structure in the surf zone associated with a plunging breaker over an idealized fringing reef profile with and without a reef crest. A two-dimensional vertical (2DV) numerical wave tank, which solves the Navier-Stoke...
