Within the Nutrient Options and Parameters frame (Figure 1) settings for many of the basic nutrient parameters may be made. The nutrient parameters have been grouped by nutrient type and can be edited by clicking on the respective button. For example to edit the Nitrogen settings the user would click on the Nitrogen button.

The user may also specify the Sorption Options. The default is "None" and parameters cannot be modified. However, if Total Active Metal (TAM) Based or Cohesive Sediment Based radial buttons are selected, the user may alter these nutrient sorption parameters with the Modify Parameters button.
The atmospheric wet deposition concentrations for the constituents being simulated with the kinetic module selected are edited via the Wet Deposition button. The dry deposition mass fluxes are edited via the Dry Deposition button.
