Irrigation conveyance loss. Technical report 04-008. Project scenario document DDW-020 final as built 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. This is the final as-built document for conveyance loss in irrigation canals. Some of the water lost from irrigation is seepage from canals and ditches. This water is not available for irrigation and therefore neither available for crop evapotranspiration (ET) nor for recharge associated with irrigated agricultural fields. However, the leakage is still a component of recharge associated with irrigation activity. Seepage from canals can be an important source of aquifer recharge. Long canals in porous soils can loose 40 percent or more of the water diverted from the source (Chavez-Morales 1985). In Idaho's climate, virtually all of this loss is associated with leakage to the aquifer (Dreher and Tuthill 1999).1 This Design Document explores options for treating canal leakage in the water budget.
