This field stores creek information. Creeks can be displayed in the map view or used for culvert design in the Location Module.
Enter the default or estimated culvert size in the format "A x B" where A is the culvert height and B is the culvert width in meters (feet for imperial project units). For pipe culverts, enter the diameter only in mm (inches). If you double click on this cell, you will get the Creek dialog in which you enter additional data.
