Vertical Sorting of Suspended Sediment Particles in the Nearshore Zone

In this paper, results of field observations of vertical distribution of suspended sediments by size, shape and density carried out in the nearshore zone of a large man-made lake are presented and discussed. It is customary believed that such a distribution of suspended sediment demonstrates quasi-steady decrease of all parameters in the direction from the sand bed towards the water surface. However, the field observations conducted revealed the. profiles with other character of change of suspended sediment concentration, sediment grain size heavy minerals and rolled particles content. It was found that the monotone decrease of those sediment parameters is just a particular case of vertical sorting of the suspended sands.
