Defence Structure Data Fields

Defence Structure objects are used to represent sea and river defence linear type structures for managing flood risk such as an embankment or sea wall.

Defence structure data can be edited on either the Defence Structure Grid Window of the Asset Grid or the Defence Structure Property Sheet.

To view and edit all defence structure data, use the Property Sheet.

The following describes all the data which can be used to define a defence structure.
