Percolation, runoff, and deficit irrigation. Technical report 04-004. Eastern Snake Plain aquifer model enhancement project scenario document DDW-002 Final As-Built Item Info

Recharge from surface-water irrigation is the largest component of aquifer recharge on the Eastern Snake River plain, supplying about 60% of the total aquifer recharge. Net ground-water withdrawals for irrigation represent about 14% of the total aquifer discharge, second only to spring flows (Garabedian 1992). Because neither net recharge nor net withdrawals can be directly measured, these are calculated using elements of the surfacewater budget. The calculations involve diversion volumes that are large relative to the overall aquifer water budget (see Design Document DDW-018). For the Model Enhancement Project, water-budget information was spatially organized using a Geographic Information System (GIS) application, and calculations performed in a FORTRAN-language computer application. This document addresses the algorithms and assumptions that were used in the FORTRAN application to calculate net recharge from surface-water irrigation and net withdrawal from ground-water irrigation.
