Abstract
A portable benthic annular flume for the in situ measurement of suspen sion feeding (biodeposition rates) and erosion potential of undisturbe d intertidal cohesive sediments with benthic biota is described. The e xperimental procedures used during deployment are also outlined. Resul ts shoeing the changes in biodeposition rates, sediment resuspension, erosion rates and critical erosion velocities associated with large-sc ale (km) and small-scale (m) spatial differences are presented. Compar ison between laboratory and in situ measurements demonstrated marked d ifferences in sediment erodability if the physical and biological prop erties of the sediment are not maintained.
