H-I Model Code Revisions. In order to reflect increased groundwater irrigation efficiencies, the input file UPDATE.DAT and H-I Model code were modified. These modifications were necessary because the H I Model incorporated in the Decree applied a single efficiency value (known as the “maximum farm efficiency” factor) to each canal service area (user) which was used in both the Historical and Compact runs. In the Historical run, the weighted efficiencies will be calculated and may vary for each calendar year (January-December) by user based on the types of irrigation system used. The weighted efficiencies and adjusted tailwater factors described in this Agreement will not be applied in the Compact run; the maximum farm efficiency factors listed in LAND.DAT will continue to be used. The H-I Model modifications are further described below.
H-I Model Code Revisions. Revisions to the H-I Model code and input file, RESR.DAT, are detailed in the following section “A” and grouped by the following tasks:
H-I Model Code Revisions. The States agree to make the following changes to the H-I Model input file, RESR.DAT, and H-I Model code using the data from Table 1 to account for the 1999 and 2006/2009 elevation-area-capacity curves developed by USACE. The updated H-I Model code has been titled “update6eV1_15.for” Table 1.
