# 5.3 - Crop Irrigation Water Requirement File (*.cir)

The crop irrigation water requirement file (*.cir) is calculated for all crop consumptive use and depletion analyses. The crop irrigation water requirement output file is generated when the output file option typout= 1 or greater in the model control file (see Section 4.4). The following information is provided by structure for each year in the simulation period:

• annual structure acreage used in analysis,
• monthly crop irrigation water requirement in acre-feet,
• annual crop irrigation water requirement in acre-feet, and
• annual application rate in acre-feet per acre.

In addition, average monthly and yearly values are also provided by structure over the simulation period. A simulation summary is also included with the above information, by year, for all simulation structures combined. An example is provided in Appendix A.
