Representation of recharge from canal leakage for calibration of Eastern Snake Plain Aquifer Model Version 2, as built. Technical report 200907. ESPAM2 Design Document DDW-V2-01 As Built ''Canal Recharge'' Item Info

This report is a Design Document for the calibration of the Eastern Snake Plain Aquifer Model Version 2 (ESPAM 2). Its goals are similar to the goals of Design Documents for ESPAM 1.1: To provide full transparency of modeling data, decisions and calibration; and to seek input from representatives of various stakeholders so that the resulting product can be the best possible technical representation of the physical system (given constraints of time, funding and personnel). It is anticipated that for some topics, a single Design Document will serve these purposes prior to issuance of a final report. For other topics, a draft document will be followed by one or more revisions and a final "as-built" Design Document. Superseded Design Documents will be maintained in a "superseded" file folder on the project Website, and successive versions will be maintained in a "current" folder. This will provide additional documentation of project history and the development of ideas. As described in ESPAM1.1 Design Document DDW-020 (Contor, 2004), water that seeps from the bed of ditches and canals is direct recharge to the aquifer and is unavailable for delivery to farm fields1 (and therefore unavailable for crop evapotranspiration, return flows to the surface-water source, or in-field incidental recharge). Representation of recharge from canal seepage affects the spatial distribution of modeled recharge, but does not affect the mass balance of recharge or the aquifer water budget. This is because if the water were not applied to canal leakage, it would be applied as incidental recharge in the irrigated-lands calculations. If we adopt an On-Farm water budget methodology, representation of the canal seepage will alter the water budget. This Design Document outlines a proposal for treatment of recharge from canal seepage for ESPAM2. It is based on discussions in ESHMC meetings during the winter of 2007-2008 and e-mail communication from members. This is a draft document designed to describe the current proposal and solicit input.
