The Intermittent nature of bottom turbulence and its relationship to sediment resuspension were examined in four contrasting flow regimes that included unidirectional currents (open channel flow in the laboratory, continental slope, tidal inlet) and oscillatory flow conditions (nearshore beach). The results indicated that sediment transport is an event based process with bulk sediment resuspension events related to turbulent velocity fluctuations. The pattern of turbulent bursting events was similar for all flow conditions with ejection and sweep events dominating the re-suspension process.
