Deliverables: Memo summarizing the approaches as well as steps in creating the various input files and <br />results. Graphs of the Clark gage flows wiIl be presented for each model. This memo wiIl also mention <br />the execution times for each approach. <br /> <br />Task 3 - Develop user documentation on "pro's and con's" of daily models <br /> <br />Purpose: There are numerous pros and cons with developing a daily simulation model. The objective of <br />this sub task will be to prepare a memorandum that can be incorporated in the CDSS documentation, to <br />educate users on major issues associated with daily modeling. <br /> <br />Approach: Develop a memorandum that discusses, at a minimum, <br />o daily vs monthly diversions during a rising, falling and steady hydrograph, <br />o daily vs. monthly data availablitly <br />odailyvs. monthly data filling, <br />. daily vs. monthly routing, <br />o daily vs. modeling return flows, <br />o daily vs. monthly reservoir operations <br /> <br />Deliverables: Memorandum as described above, expected to contain approximately 2 figures and 10 <br />pages of text. <br /> <br />Task 4 - Recommend approach for basinwide model <br /> <br />Purpose: Detennine scope and budget for basinwide daily model. <br /> <br />Approach: Considering experience and results of Task 2 and input from the State, recommend an <br />approach for developing a daily model of the entire Yampa basin. Choice of approach should consider <br />execution time and data management issues (e.g., file sizes) for the daily model. For example, it should <br />recognize the need to fill historical gage and/or diversion data, as applicable, in the basin outside the <br />pilot area. Need for modifying CDSS tools (potentiaIly Statemod output requirements, Mixed Station <br />model, or DMI's) should be identified. Work tasks will be outlined for the selected approach and <br />development cost of the basinwide daily model will be estimated. <br /> <br />Deliverable: Draft and final memos describing selected approach to a basinwide daily model, and <br />rationale for approach. Memo shall include description of work tasks, and estimated budget and <br />schedule if these tasks are to be completed by Boyle. Elements that Boyle cannot execute because they <br />lie outside of Boyle's expertise or authority, will be itemized, although detailed descriptions thereof will <br />not be included. <br /> <br />Task 5 - Develop basinwide Yampa model for 1909-1996 <br /> <br />Purpose: Develop a daily simulation model for the extended historical period. <br /> <br />Approach: This task will be undertaken only after written authorization from the State, based on <br />conclusions of Task 4. In accordance with the scope and budget developed in Task 4, prepare the <br />basinwide Yampa model. Calibration will focus on alterations made from the monthly model, for <br />example, adjustments to patterns selected to disaggregate from monthly to daily. <br />
