heal.abstract	ABSTRACT: This paper presents results of physical and numerical model studies of spreading of suspended sediments in coastal waters under the action of waves and currents. Simulations on movement and settlement of sediment particles with various physical properties (specific density, grain-size, shape) are realized using a simplified particle-tracking numerical model. The complex grain-size composition of sediments (as per the sieve analysis) is introduced in the model as an essential characteristic that influences suspended transport and sedimentation. A laboratory study has been carried out in order to provide data for validation and verification of the numerical model. Emphasize was put on studying the active and neutral dispersion of various fine sand sediments. Laboratory study was realized in two stages in the Tidal Flume and in the Dredging Flume of WL Delft Hydraulics, the Netherlands. The concentration of suspended sediments was measured, as well as the shape and the thickness of the foot-print at the bottom after sedimentation. Measurements were done for various sediment properties, type of sediment supply, current range, and wave characteristics. The comparison of calculated and measured data has shown a good correspondence that encourages the authors for further development and application of the proposed numerical model. © 2005 Taylor & Francis Group.	en
