The Velocity Opts frame controls the type of velocity plot to display. These options can be combined. For example, the user can plot the 2D vectors over cells that have been colored base based on vertical velocity magnitudes. The details of the formats of the color ramps and vector styles is adjusted using the Display Options form. The vertical velocity can be displayed for each layer, or depth averaged, by selecting the Vertical checkbox and the appropriate Layer Setting. When Vertical is selected all the time series extracted are also in the Z direction.
The Show Flow checkbox, when checked, causes EFDC_Explorer to report flows instead of velocities when LMC'ing on the form and when cutting a profile.

The water flux tool computes either total discharge across the section or on a layer by layer basis, based on the options selected on the ViewPlan form. If a single snapshot is selected then the results will be displayed in a dialog box and also placed onto the clipboard. If Show Time-series is selected then the user must specify which flow component desired. The following is a description of each type:
Total Flow:The absolute value of the total flux across the section.
EW Flow:The sum of the flows in the EW (based on the cell map, i.e. EW=I component flow)
NS Flow:The sum of the flows in the NS (based on the cell map, i.e. NS=J component flow)
Dominant Flow:Computes the total flow across the section and assigns a sign based on dominance.
The Dominant Flow option is the most useful for most applications.
