This file contains land use and management decision tables.

The structure of the decision table files is different than that of most other SWAT+ input files. As usual, the first line is reserved for a title. The second line in the file specifies the total number of decision tables included in the file.

Each decision table has three parts, which all have their own headers. First, the name of the decision table and the number of conditions, alternatives, and actions are specified.

Field	Description	Type
name	Name of the decision table	string
conds	Number of conditions	integer
alts	Number of alternatives	integer

obj	Object type	string
obj_num	Object ID	integer
lim_var	Limit variable	string
lim_op	Limit operator	string

Finally, the outcomes and actions are defined. The number of lines used for this part of the decision table depends on the number of actions.
