<p><b>New page</b></p><div>The FreeVerticalMovement is used to add to the vertical flow a vertical<br />
movement. Presently the module is prepared to impose a constant settling velocity<br />
or a settling velocity function of salinity concentration and fine sediments concentration. <br />
In the future other types of vertical movement will be computed like phytoplankton <br />
up and down movements to optimize the nutrients uptake and/or to reduce mortality due to grazing.<br />
<br />
== WaterProperties_x.dat==<br />
For each particulate property it's possible to define a settling velocity<br />
condition. By default no settling velocity is assumed.<br />
<beginproperty><br />
VERTICAL_MOVEMENT : 1 <br />
<endproperty><br />
== FreeVerticalMovement_x.dat==<br />
An example presented below defines for the cohesive sediment property a constant <br />
settling velocity of 1e-5 m/s or 0.01 mm/s. For salinities below 3 psu the settling<br />
velocity is zero. The advection transport associated with settling is computed implicitly.<br />
