The GSSHA Nutrients dialog is accessed by turning on Nutrients in the other options section of the GSSHA Job Control Parameters dialog, then clicking Edit parameters... to the right of the option. The following tabs are found in this dialog:

  • Point Sources
  • Non-Point Sources
  • Other
  • Uniform Properties

The following buttons are found at the bottom of the GSSHA Nutrients dialog:

  • Help – Opens this article in a web browser.
  • OK – Saves all changes and closes the GSSHA Nutrients dialog.
  • Cancel – Discards all changes and closes the GSSHA Nutrients dialog.

General

There are a number of things that should be kept in mind regarding GSSHA nutrients

Point Sources

The Point Sources tab in the GSSHA Nutrients dialog.

When defining point sources, determine the I, J index of the cell if defining an overland point source, or the Link, Node index if defining a stream point source. The I, J index can be determined from the grid cell properties in the Properties section of the Main Graphics Window. The link number can be determined by turning on the link number display on the Map tab under "Map Data" in the Display Options dialog.


Non-Point Sources

The Non-Point Sources tab in the GSSHA Nutrients dialog.

When defining non-point sources, define a grid or stream index map associated with the non-point source.


Other

Nutrients dialog showing the Other tab.

Enter nutrient concentrations in the Other tab. These concentrations will be applied to rainfall input.


Uniform Properties

Nutrients dialog showing the Uniform Properties tab.

The Uniform properties tab contains default values for uniform nutrient properties. It's possible to adjust these values.
