The following form (Figure 1) is used to set the initial conditions for any water column parameter.  Depending on which parameter was selected elsewhere in EE, the form is displayed with the parameter being set shown in the title bar.

Several options are available for IC settings.  Which option is used depends on the model needs and available data.

...

If this option is selected, the Layer Options frame is disabled since this option sets the IC for all layers.  This option requires an ASCII data file in the format shown in B-6 (Figure 2).  When the Apply button is pressed, EE interpolates these data onto the water column initial conditions both horizontally and vertically (all active layers).  Any number of vertical profiles can be used.  If the layers are above or below the defined vertical profile, the layer assignments will be constant at the last valid elevation.

1. Select From Profile Data check box under Values to Set frame
2. Add or remove profile data files by using Add file or Remove file buttons under Data files frame.
3. Select All grid cells check box if user want to apply constant value for the whole domain or Only grid cells inside polygons check box in Grid options frame to use if needed to apply for cell inside polygons. If user select Only grid cells inside polygons check box, Polygon files frame will enable and user can add or delete polygons by clicking on Add file or Remove file buttons. Make sure that polygon files are applied if user want to assign initial condition for cells inside polygons
4. Click Apply.  EE will report the number of horizontal cells it changed/updated.
5. Repeat for different sub-domains, if needed.

* Notice: Due to multiple classes modules (i.e. sediment, water quality, toxic, ...), there will have an additional frame name's Class Options in the form to select each class or all classes will be set at once as shown in Figure 3
