Instrumentation for direct measurements of wave‐driven flow over a fringing reef crest

Effect of Crest Roughness on Flow Characteristics over Circular Weirs

Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.  In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...

Wave setup over a Pacific Island fringing reef

Boundary layer turbulence and flow structure over a fringing coral reef

Measurements of velocity and rates of turbulence were made across a fringing coral reef in the Gulf of Aqaba, Red Sea, to determine the effect that the rough topography has on boundary layer mixing and flow dynamics. Observations were made at two fore-reef sites and a nearby sandy slope. The friction velocity, u*, and drag coefficient, CD, were determined directly from turbulent Reynolds stress...

Fringing reef growth and morphology: a review

Fringing reefs are generally not simple veneers of coral growth along tropical shorelines. Extensive research over the past few decades, based on radiocarbon dating of Holocene reef deposits, has indicated that they can develop in a complex variety of ways even though the surface morphology may appear relatively simple. The principal factor that appears to determine the growth and morphology of...

The Fringing Reef Coasts of Eastern Africa

Sea-level changes through the Quaternary era have provided recurrent opportunities for the biosphere to significantly shape the coastal geomorphology of eastern Africa. Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the oceanfacing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces th...
