To change the contour settings for ponds
1 From the Grading menu, choose Pond Settings ä Contours to display the Pond
Contour Settings dialog box.
2 In the Contours section, choose one of the following methods for creating the
contours:
n
Select Relative to draw contours at a specific distance below the pond
perimeter. (Specify the distance with the Elevation setting.) For example, if
the pond perimeter is at an elevation of 781.5 ft, and the Elevation setting is
2 ft, the nearest contour below the pond perimeter is created at 779.5 ft.
n
Select Absolute to draw contours at the nearest whole interval below the
pond perimeter. (Specify the intervals with the Elevation setting.) For
example, if the pond perimeter is at an elevation of 781.5 ft, and the
Elevation setting is 2 ft, the nearest contour below the pond perimeter is at
an elevation of 780.0 ft.
NOTE
The Relative and Absolute options are used only if the Elevation option is
selected. For more information, see the Elevation option below.
TIP
Pond volumes are determined from the contours created for the pond.
For more accurate pond volume calculations, the contour increment
should be set to a maximum of 1.
3 Configure the settings for either normal or highlighted contours:
n
Select Normal to draw a contour for every interval specified on the left side
of the dialog box. (The settings on the left side of the dialog box affect how
normal contours are created).
n
Select Highlight to draw a highlighted contour for every interval specified on
the right side of the dialog box. (The settings on the right side affect how
highlighted contours are created).
