4 In the Station box, type the first station number.
5 In the Surface name box, type the surface name.
6 In the Thickness box, type the thickness of the material from the first surface
(i.e., topsoil) to the second surface (i.e., clay).
7 For the first surface, the Depth value is zero (0).
The first surface has a thickness value, but not a depth value, because for all
surfaces, depth is measured from the top surface down. The thickness value for
a surface is the value measured from that surface down to the next surface. For
example, the second surface can have depth and thickness values. For the
second surface, the depth is measured from the top surface down to the second
surface. The thickness for the second surface is measured from the second
surface down to the third surface. For the third surface, the depth is measured
from the first surface down to the third surface, and the thickness is the
measurement between the third and fourth surfaces. The last surface you enter
has a thickness of zero (0) to indicate that there are no surfaces below it.
NOTE
For the first surface, the Depth box is grayed out. When you begin to enter
interpolation values, you can choose to enter the values as depths or as
thicknesses. By default you must enter a thickness for the first surface
because the first surface does not have a depth value.
8 Click OK to continue.
The Interpolation Surface Control Editor dialog box is displayed.
9 Choose the subsurface data entry type.
There are two options at the top of the dialog box for subsurface data entry
type: Thickness and Depth. When you select Thickness option, any thickness
entry results in the automatic entry of the associated depth data for the
particular surface. When you select the Depth option, the opposite is trueany
depth entry results in the automatic entry of associated thickness data.
10 Create the interpolation control data. You can use either or both of the
following options:
n
Click Ins Sta to create interpolation control for a new station. Use this
method to create a new station and enter surface depth/thickness data for
multiple surfaces. For more information, see INS Sta Option in this
chapter.
n
Place your cursor in the row of an existing station and click Ins Srf. Use this
method to enter surface data for an existing station. For more information,
see INS SRF Option in this chapter.
NOTE
Interpolation control MUST span a range of stations. You cannot assign
interpolation control to station 0+00 and expect to see those surfaces on
the section for station 0+00. For example, you must span stations by
assigning the interpolation to station 0+00 and, using the same surfaces, to
station 0+50 to be able to see the different surfaces for station 0+00 and
0+50.
11 To edit the values for a station, place your cursor in the row you want to change
and click Edit.
12 To delete a row of surface data for a station, place your cursor in the row you
want to delete and click Del Surf.
