- Description:
- 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 report on the calculation of recharge on non-irrigated lands. This Design Document discusses calculation of two spatially-distributed components of the aquifer water budget; recharge from precipitation on non-developed lands and spatially-distributed recharge and discharge from land uses that comprise a small fraction of the study area. These minor-use areas are dry farms, cities, and wetlands. This design document presents the method used for calculating recharge from precipitation using GIS grid maps of monthly precipitation (Daly and Taylor 2001) and generalized soil maps (Garabedian 1992). This calculation was performed for all the areas of the plain not represented as dry farms, cities, or wetlands. These minor-area lands were represented as separate polygons to which a fixed net recharge rate was applied. The outcome was a single GIS grid map per stress period, covering the entire plain and representing recharge for non-irrigated land use. In calculating the water budget, the recharge tool (comprised of a GIS component and a Fortran component) considered maps of irrigated lands and applied either the irrigated-lands recharge calculation or the recharge depth from the GIS grid map to appropriate areas of each model cell. The irrigated-lands map is described in Design Document DDW-015 and the irrigated-lands recharge calculation is described in Design Documents DDW-001, DDW-002, DDW-021 and DDW-022.
