 # Transport
-State variables in the water column (DIN, Phyto, Zoo and Det) are transported by tidal currents. This transport is modeled as exchange rates between the neighboring compartments. It is assumed that the exchange rates are bi-directional, i.e. the exchange rate [m<sup>3</sup> d<sup>-1</sup>]. from compartment 1 to compartment 2 is the same as the exchange rate from compartment 2 to 1.
