The number of groups varies and depends on the modules simulated in the model. Once selecting a group for the Primary Group completed, a list of parameters for the selected group is displayed in the Parameter.

The Profile Definition frame needs to be set before a profile can be extracted from EFDC. There are three options shown in Data Extraction (new) 2132574327. It is possible to select a value of I to extract the active J cells along that I, or select a value of J to extract the active I cells along that J. The third option is to use a "Drape Line", which is a polyline in the same coordinate system as the LX, LY data. The I & J's along this line will be assembled, and the profile will be output along with that slice. If an I or J extraction is used, the user can scroll up and down the select a coordinate.
Define Parameter to Plot

selecting which parameters will be displayed. First, it is necessary to select the Primary Group, then select the Parameter from that group is available to choose. It is required to click the left arrow button to confirm the selection. It is possible to select more than one parameter for the plot.
The

parameters selected are displayed in the Parameters to Plot frame, where the user can also remove the parameter by using the right arrow button. The user can save the current 2DV layout by clicking the Save button or load an external 2DV layout by selecting the Load button. The Up and Down buttons will change the order of the parameter in the displayed plot.
The Update button will replace the currently highlighted parameters in the Parameters to Plot frame with the currently selected parameters in Define Parameter to Plot frame.
The Properties button will open the 2DV View Properties form where the user can configure the color ramp, contour, precision, range, and other settings (2132574327).
2132574327 and 2132574327 is a 2DV View example for selecting the temperature of the I = 38 at a specific time.

Data Extraction of EFDC Arrays
A new option for 2DV View has been developed to the EEMS11.3 version. It allows to view 2DV plot of parameters of EFDC arrays. To select EFDC Array's parameters are similar to other parameters described above. Select EFDC Arrays for the Primary Group, and then select a parameter from the drop-down list as shown in 2132574327. The meaning of these parameters is described in 2132574327 below. An example of 2DV View for vertical eddy viscosity is shown in 2132574327.
