This thesis investigated through a laboratory and field experiment how hydrodynamic processes affect the temporal and spatial variability in size, concentration and transport of sediment in a fringing coral reef. At a small (within canopy) scale, suspended sediment is unrelated to shear stresses derived from the logarithmic mean current profile or turbulence measured above the roughness, but is instead correlated to the bed stresses within the roughness canopy layer. At large reef-wide scales, sea-swell waves, infragravity waves and currents may all contribute to sediment transport on a reef flat, while in a lagoon, the sea-swell waves and currents are important.
