Define Composite Liners

The overall layer structure of a Composite Liner is defined with the Define Composite Properties option.

The Define Composite Properties dialog allows you to define a Composite Liner by selecting individual liners (defined in the Define Liner Properties dialog), and a joint (defined in the Define Joint Properties dialog), in the desired sequence and combination.

To define a Composite Liner:

1. First define the properties of the individual layers of the Composite Liner, using the Define Liners option.
2. If you are including a joint in the Composite Liner, define the properties of the joint using the Define Joints option.
3. Now select the Define Composite option from the toolbar or the Properties menu.
4. In the Define Composite Properties dialog, select the Composite Type that you would like to define.
   1. If you are NOT including a joint, then you can define a Composite Liner with 2, 3 or 4 layers (i.e. Composite Type = 2 liners, 3 liners or 4 liners)
   2. If you wish to include a joint, then you can define a Composite Liner with 1, 2, 3 or 4 layers (i.e. Composite Type = 1 liner (with slip), 2 liners (with slip), 3 liners (with slip) or 4 liners (with slip)).
5. Use the drop-lists at the left of the dialog to select the desired sequence of liners which will be used, and also the joint, if included.

Note: the liner (and joint) names which appear in the drop-lists in the Define Composite dialog, are the liner (and joint) names, which you entered in the Define Liner Properties and Define Joint Properties dialogs, when you defined the liner (and joint) properties.

6. If your Composite Liner consists of 2, 3 or 4 liners (with or without a joint), you can assign the stage of application of liners 2, 3 and 4, relative to the stage of application of the FIRST liner layer, using the drop-list boxes at the right of the dialog.

NOTE: the stage of application of the FIRST liner layer, is determined with the Assign Properties option (see below).

7. If your Composite Liner includes a joint, and more than one layer (i.e. Composite Type = 2 liners (with slip), 3 liners (with slip) or 4 liners (with slip)), then you can use the Joint Placement option to define the placement of the joint with respect to the layers. The joint can exist between the rock/soil and the first layer, or between any two consecutive layers of the composite liner.
8. When you are finished defining the Composite Liner, select [OK].

Composite Liners are assigned their initial stage application, in exactly the same manner as regular (single) liners, using the Assign Properties option. This determines the stage of application of the FIRST layer of the Composite Liner. The stage of application of all subsequent layers of the Composite Liner, is determined in the Define Composite Properties dialog, as described above.
