Activate the Temperature Module
The Graphical User Interface (GUI) for the Temperature module in EE can be activated from the EFDC+ Modules, as shown in Temperature Visualization#Figure 1
Figure 1. Active Temperature Modules.
Settings
After RMC on the Temperature module, the user can access the Settings, Initial Conditions, and Time Series options (Figure 2).
Figure 2. Temperature Module: RMC Options.
In order to set up the Temperature Module, the users should RMC Settings and then the Temperature Parameters form is displayed with five tabs. Each tab has different parameters that may be adjusted as described in the following sections (Figure 3).
Figure 3. Temperature Parameters.
Initial Conditions
- Initial Conditions for Water Temperature: this can be set to a constant value or assigned to vary spatially. To set either of these options select the Assign button. To set a constant value simply enter a value in the Constant field under the Values to Set frame. The user can set this constant to certain layers in the Layer Options frame. If users want to use spatially varying initial temperature determined by a polygon, they should check the box and press The Apply Cell Properties via Polygons form is shown in Temperature Visualization#Figure 5. If the values to be set vary spatially varying temperature based on XYZ or from vertical profile data, they should select one of these two options in the Values to Set frame. The user should then browse with the Add file button in the Data files frame to add these data sets. Various interpolation options are provided in the Interpolation Options frame, including replacement of existing data, and using the maximum or minimum values. Selecting the More button provides further interpolation options including order of inverse distance weighting (IDW) interpolation, number of neighboring points, and number of quadrants.
- Initial Conditions for Bed Temperature: It is able to set constant bed temperature by setting a value in the Uniform Bed Temperature box or check Use Spatially Variable Bed Temp and Thickness checkbox to assign a spatially varying initial temperature, by layer (Temperature Visualization#Figure 6). The options and format of data files to upload to are described in Apply Cell Properties via Polygon. It also can select to apply cell properties for a specific layer or all layers in the model.

Visualization
2DH View
The temperature can be visualized and animated in 2DH View. These can be added to the 2DH View by clicking the Add button in the 2DH View’s Layer Control then select Primary Group: Water Column and Parameter: Temperature as shown in Temperature Visualization#Figure 7
Figure 7. Temperature Layer in 2DH View.
Time Series
The graphic of temperature time series can be visualized by click the Time Series button or the icon 
of the main toolbar. The Extract Time Series Data tab appears as shown in Temperature Visualization#Figure 8. It is possible to plot the time series for a single cell or multiple cells. Firstly, defying the cells to plots is in the box under Selected Cells. When the L index is entered the corresponding I and J indices are filled automatically. The parameter should be defined in the box, Primary Group: Water Column and Parameter: Temperature. Add and remove the parameter can be adjusted by the left and right arrow button. The user may define the start and stop day for the time series in Time Series Start/Stop frame (note that the start and stop days should be within the model's start and end date). Clicking OK plots the selected graphs

Vertical Profiles
The graphic of salinity vertical profiles can be visualized by click the Vertical Profile button or the icon 
of the main toolbar. The Vertical Profiles tab shows in Temperature Visualization#Figure 10. It is possible to plot the vertical profiles for a single cell or multiple cells. Firstly, defying the cells to plots is in the box under Selected Cells. When the L index is entered the corresponding I and J indices are filled automatically. The parameter should be defined in the box, Primary Group: Water Column and Parameter: Temperature. Add and remove the parameter can be adjusted by the left and right arrows. It is possible to import an external file to compare with model results, that function is useful for the model calibration and validation.

Longitudinal Profiles
The graphic of salinity longitudinal profiles can be visualized by click the Longitudinal Profile button or the icon 
of the main toolbar. Temperature Visualization#Figure 12 show the Data Extraction for Longitudinal Profile form. This form is similar to the Data Extraction for 2DV View form. Firstly, it is necessary to define the profile using the drape file or I, J indices and then define the parameter to the plot. Once everything is ready, click OK to generate the plot. Temperature Visualization#Figure 13 shows a longitudinal profile for salinity and bottom elevation along with the profile I=39.
