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.

Point sources, such as that from a discharge pipe, are defined on the Point Sources tab. 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.

For any contaminant source being modeled as a point source, a mass curve or a concentration curve must be defined in order to be selectable from the drop-downs for each contaminant. These must be entered separately from the non-point source curves.

The Type drop-down has the following options:

  • "All" – Displays all point sources.
  • "Overland" – Displays only overland point sources.
  • "Stream" – Displays only stream point sources.

The Show drop-down has the following options:

  • "All" – Shows all of the selected Type.
  • "Selected" – Shows only those of the selected Type that are selected in the Main Graphics Window.

The following buttons appear on the Point Sources tab:

  • Add – Adds a new point source to the spreadsheet on this tab.
  • Delete – Immediately deletes the selected point source.
  • Mass Curves... – Opens the XY Series Editor dialog to allow defining of a mass curve.
  • Concentration Curves... – Opens the XY Series Editor dialog to allow defining of a concentration curve.

The spreadsheet has the following rows:

  • Name – Alphanumeric field. Enter the name of the point source.
  • Type – A drop-down with the following options:
    • "Overland" – Select if the point source is an overland source.
    • "Stream" – Select if the point source is a stream source.
  • I / Link – The I coordinate (for an overland source) or the link number (for a stream).
  • J / Node – The J coordinate (for an overland source) or the node number (for a stream)
  • Flow – A drop-down of all available point source concentration curves.
  • Nitrite (NO2-) – A drop-down of all available point source mass and concentration curves.
  • Nitrate (NO3-) – A drop-down of all available point source mass and concentration curves.
  • Ammonium NH4+ – A drop-down of all available point source mass and concentration curves.
  • Organic Nitrogen (ON) – A drop-down of all available point source mass and concentration curves.
  • Organic Phos. (OP) – A drop-down of all available point source mass and concentration curves.
  • Diss Phosphorous (DP) – A drop-down of all available point source mass and concentration curves.
  • Phosphate (PO4) – A drop-down of all available point source mass and concentration curves.
  • Algae (Alg) – A drop-down of all available point source mass and concentration curves.
  • CBOD – A drop-down of all available point source mass and concentration curves.
  • Dissolved Oxygen (DO) – A drop-down of all available point source mass and concentration curves.

Non-Point Sources

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

Non-point sources, such as rainfall, are defined on the Non-Point Sources tab. When defining non-point sources, define a grid or stream index map associated with the non-point source. For any contaminant source being modeled as a non-point source, a mass curve or a concentration curve must be defined in order to be selectable from the drop-downs for each contaminant. These must be entered separately from the point source curves.

The Type drop-down has the following options:

  • "All" – Displays all non-point sources.
  • "Overland" – Displays only overland non-point sources.
  • "Stream" – Displays only stream non-point sources.

The Show drop-down has the following options:

  • "All" – Shows all of the selected Type.
  • "Selected" – Shows only those of the selected Type that are selected in the Main Graphics Window.

The following buttons appear on the Point Sources tab:

  • Add – Adds a new non-point source to the spreadsheet on this tab.
  • Delete – Immediately deletes the selected non-point source.
  • Mass Curves... – Opens the XY Series Editor dialog to allow defining of a mass curve.
  • Concentration Curves... – Opens the XY Series Editor dialog to allow defining of a concentration curve.

The spreadsheet has the following rows:

  • Name – Alphanumeric field. Enter the name of the non-point source.
  • Type – A drop-down with the following options:
    • "Overland" – Select if the non-point source is an overland source.
    • "Stream" – Select if the non-point source is a stream source.
  • Index Map – A drop-down of all available index maps in the GSSHA project.
  • Rainfall – Turn on if the non-point source is rainfall.
  • Flow – A drop-down of all available non-point source concentration curves.
  • Nitrite (NO2-) – A drop-down of all available non-point source mass curves.
  • Nitrate (NO3-) – A drop-down of all available non-point source mass curves.
  • Ammonium NH4+ – A drop-down of all available non-point source mass curves.
  • Organic Nitrogen (ON) – A drop-down of all available non-point source mass curves.
  • Organic Phos. (OP) – A drop-down of all available non-point source mass curves.
  • Diss Phosphorous (DP) – A drop-down of all available non-point source mass curves.
  • Phosphate (PO4) – A drop-down of all available non-point source mass curves.

Other

Nutrients dialog showing the Other tab.

The Other tab allows nutrient concentrations to be entered. These concentrations will be applied to rainfall input.

The following rows appear in the spreadsheet on this tab:

  • Temperature (C) – A decimal value in degrees Celsius.
  • Channel pH – A decimal pH value.
  • Nitrite, NO2 – A decimal value in milligrams per liter.

  • Dissolved oxygen, DO – A decimal value in milligrams per liter.
  • Dissolved organic carbon, DOC – A decimal value in milligrams per liter.
  • Fraction organic carbon in DOC – A decimal percentage value.

Below this point, any additional contaminants created in the GSSHA Contaminants dialog will be listed.

Uniform Properties

Nutrients dialog showing the Uniform Properties tab.

The Uniform Properties tab contains user-editable default values for uniform nutrient properties. KOC is "the 'distribution coefficient' (Kd) normalized to total organic carbon content.[1] KM (the Michaelis constant) is "the substrate concentration at which the reaction rate is half of its maximal value".[2]
