<br />1040 <br /> <br />Approach: <br />1. Boyle: Execute Statemod with the Phase 1II data files, using the ,ddh demand file; execute <br />Statemod with the Phase 1II data files, using the .ddm demand file. <br />2. Boyle: Examine the big picture plot and paired monthly hydrographs for key points <br />throughout the basin for both scenario comparisons. This investigation will be done "on the <br />fly" on the computer screen to gain an understanding of overall condition of the model with <br />respect to calibration. Adjustments will be made to aggregated node locations, return flow, <br />efficiencies, and demand, as well as base hydrology. Adjustments to the Phase II data set <br />will also be considered. It is expected that approximately 20 hours will be spent on <br />calibration at this stage. <br />3. Boyle: Big picture plots and hydrographs for approximately 9 stream flow locations, 20 <br />explicitly modeled diversion structures, and 9 explicitly modeled reservoirs will be captured <br />in order to present these results to the State team. These points should offer good coverage <br />of the basin as well as highlight any areas that warrant review and discussion with the State, <br />4, Boyle: Meet with the State and brief them on the calibration. This meeting will be a half- <br />day to day-long work session during which the State team members can examine results at <br />any site. Alternative strategies for addressing unsatisfactory calibration can be discussed and <br />potentially executed on the spot. The State will participate in this midpoint briefing on the <br />calibration, and direct Boyle as to, for instance, amount of time appropriate for resolving <br />minor problems, or preferred tradeoffs if agreement in one area degrades agreement in <br />another area. <br />5, Boyle: Based on conclusions of the midpoint briefIng session, continue to pursue calibration <br />to the extent determined by the State, For the purposes of budgeting, assume that this effort <br />will not exceed 8 hours. If additional effort is required to complete this part of the <br />calibration, it will be considered out of scope. <br />6, Boyle: Produce final big picture plots and paired hydrographs for key gages, diversions, <br />and reservoirs for Phase III historical scenario vs, gaged data, Phase III historical scenario <br />vs. Phase II historical scenario, and Phase 1II calculated scenario vs. gaged data, <br />7, Boyle: Prepare a Task Memorandum documenting the calibration process and results, The <br />memorandum will generally describe the differences between the initial model run and the <br />final run. It will!lQ1log every interim run or trace the exact procedures followed, The <br />plots created in Task 3,14 will be included or referenced by filename in the Task <br />Memorandum, The State will review a draft of the memo and provide written comments <br />within two weeks of receiving the draft. Boyle will finalize the memo within two weeks of <br />receiving the State's comments, <br /> <br />Deliverables: <br />1, Statemod simulations for three scenarios. <br />2, Calibration adjustments to Statemod input files. <br />3, Interim graphs and tables to be presented at the midpoint briefing session, <br />4. State review of calibration process. <br />5, Additional calibration adjustments to Statemod input files. <br />6, Big picture plot and paired hydrographs at approximately 38 sites, to be included in the Task <br />Memorandum <br /> <br />Phase IlIa Scope of Services <br /> <br />A-40 <br /> <br />June 12, 1996 <br /> <br />
