# 5.7 - Detailed Structure Water Budget by Land Category File (*.4wb)

The detailed structure water budget by land category file (*.4wb) is generated with the output file option typout= 4, 5, 14 or 15 in the model control file (see Section 4.4). As discussed in Section 4.15, acreage for each ditch is input by four land categories; sprinkler irrigated with surface water-only, flood irrigated with surface water only, sprinkler irrigated supplemented with ground water, and flood irrigated supplemented with ground water. If the structure represents ground water use only, the surface water category acreage would be zero. This option provides the detailed information outlined in the Farm Water Budget Output File (*.dwb) broken out by land category for specified structures (typout= 4 or 14) or all structures (typout= 5 or 15) as defined in the model control file. An example is provided in Appendix A. Also see Appendix A for a list of the parameters available in this output file, and information on the model control options that are set to create each output parameter.
