Fig. 3.
The Lagrangian sediment-mixing model and model behavior. a Lagrangian mixing model schematic after ref. 16. The three curves show the effect of varying z scale on the depth- dependent diffusivity (K v)–or mixing intensity. z 0 is held constant in these three scenarios and shown at the left with a small arrow. Other factors modifying the average mixing depth of particles is K 0 (maximum vertical diffusivity) and sedimentation rate (w s). The effect of these factors on the average mixing profile of a point event is shown in b, a simplified version of a figure from ref. 16
