Determination of crop mix, revision one. Technical report 04-025. Scenario document number DDW-001 Item Info

Design documents are a series of technical papers addressing specific design topics on the eastern Snake River Plain Aquifer Model upgrade. Each design document will contain the following information: topic of the design document, how that topic fits into the whole project, which design alternatives were considered and which design alternative is proposed. In draft form, design documents are used to present proposed designs to reviewers. Reviewers are encouraged to submit suggested alternatives and comments to the design document. Reviewers include all members of the Eastern Snake Hydrologic Modeling (ESHM) Committee as well as selected experts outside of the committee. The design document author will consider all suggestions from reviewers, update the draft design document, and submit the design document to the SRPAM Model Upgrade Program Manager. The Program Manager will make a final decision regarding the technical design of the described component. The author will modify the design document and publish the document in its final form in .pdf format on the SRPAM Model Upgrade web site. Final model documentation will include all of the design documents, edited to ensure that the "as-built" condition is appropriately represented. The calculation of net recharge from surface water irrigation, or the net withdrawal from ground water irrigation, requires a calculation of evapotranspiration (ET). Calculation of ET requires knowledge of the crop mix. Differences in crop mix can change average ET by as much as ten percent, which translates into 1.7 x 1010 ft3 (400,000 acre feet), or approximately seven percent of the aquifer water budget. This design document examines various sources of crop-mix data, the challenges posed by limitations of each, and explains the selected method to determine crop mix for use in the study. Appendix 2 is the revision, dated 2-13-2003, published 11-15-2004.
