In this paper, a simple conceptual model for the net transport of suspended sediments associated with a simple harmonic tidal current superimposed on a spatially varying near-bottom concentration is developed. Because by accounting for the response of the sediment concentration in the water column to the varying near-bottom concentration, it predicts a net transport rate which is proportional to and in the downward direction of the imposed bottom concentration gradient, i.e. expressible as a diffusive process.
