<br />1064 <br /> <br />Subtask 2.08 <br /> <br />Assign Aggregated Irrigation Efficiencies <br /> <br />(( 7,{^-oO <br /> <br />Objective: Assign and incorporate average monthly efficiency values for each aggregated <br />irrigation structure into the Statemod ,dds input file. <br /> <br />Prerequisite: Demandts ill be modified to calculate average efficiency for diversion Structures <br />spe ' e by the user, <br /> <br />Assumption: Generally, the acreage-weighted average of irrigation efficiencies for explicitly <br />modeled structures represents irrigation efficiency adequately for aggregated <br />structures. <br /> <br />Approach: <br />1, RTIWR: Run demandts using the Phase II STATEMOD input files to generate a basin wide <br />efficiency report. <br />2, STATE: Document the determination of monthly efficiency values in a 1-2 page <br />memorandum. RTI will provide written comments on this memo before the State finalizes <br />the memo. <br /> <br />Subtask 2.09 <br /> <br />Deliverables: <br />L Basin wide efficiency numbers, <br />2. A memorandum documenting the monthly efficiency associated with each of the aggregated <br />irrigation Structures, <br /> <br />Estimate aggregated irrigation structure demands and historic diversions ~ 7' A I ~" w <br /> <br />Prepare Statemod ,ddh and .ddm input files. The .ddh file will contain historical <br />diversions for Phase II structures and calculated demands for aggregated structures. <br />Also create the white,dds file using the basin wide efficiency from Phase II. The <br />,ddm file will contain calculated demands for all irrigation structures. <br /> <br />Objective: <br /> <br />Prerequisite: <br /> <br />Demandts will be modified to sum the irrigation time series for individual structures <br />represented in aggregated fashion. <br /> <br />Historical diversion records for small irrigation structures are generally incomplete orl <br />inadequate for modeling demand. For the aggregated structures, demand at the <br />headgate will be calculated by estimating consumptive use for all associated irrigated <br />acreage, and dividing by estimated efficiency. <br /> <br />77 <br /> <br />Assumption: <br /> <br />Approach: <br />L STATE: Prepare ASCII mes that list the County/HUC for each structure in the White River <br />Basin that is tied to an irrigated parcel. <br /> <br />Phase IlIa Scope of Services <br /> <br />A-16 <br /> <br />June 12, 1996 <br />
