The form of Data Extraction assists users to define the location of the profile and the parameters to be displayed in 2DV View.

The Profile Definition frame needs to be set before a profile can be extracted from EFDC. There are three options shown in Figure 1. The user may either 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.

The Define Parameter to Plot frame requires the user to select which parameters will be displayed. First, the user should choose the Primary Group, then select the Parameter from that group. 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 is able to 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 (Figure 2).

Click OK to plot 2DV View.

The latest version of EEMS supports a new function to view the parameters of EFDC arrays in 2DV. In Data Extraction form, the primary group should be selected as EFDC Arrays and then the drop-down list of parameters are available.

 

Figure 3. EFDC Arrays in 2DV.

  • DZC : VERTICAL LAYER THICKNESS AS DECIMAL FRACTION OF WATER DEPTH DIMENSIONLESS

  • QQ : TURBULENT INTENSITY

  • DML : TURBULENCE DIMENSIONLESS LENGTH

  • LENGHT : TURBULENT LENGHT SCALE

  • AV : VERTICAL EDDY VISCOSITY L*L/T

  • AB : VERTICAL EDDY DIFFUSVITY L*L/T

After selecting the concerned parameter, click OK and the 2DV View presents as figure below.
