Technical support is budgeted through this <br />task to facilitate invoicing the first 26 tasks. The following guidelines describe approximate, <br />anticipated distribution of budget for this task: <br /> <br /> Percent of Subtask 11.28 <br />Tasks bud2et <br />11.3 Load Database 0 <br />11.5 Develop method 30 <br />11.6 Enhance Demandts 15 <br />11.7 Verify diversion estimate 30 <br />11.8 Misc State tasks 10 <br />11.10 Fill missing baseflow 10 <br />11.11 Deshm interface 5 <br />Total 100 <br /> <br />Deliverables: None <br /> <br />Task 12 - Stochastic Data Development <br /> <br />Responsibility: Ayres/Boyle <br /> <br />Objective: To develop stochastic models for the generation of streamflow data, and to use these <br />models to generate such data for use in the CRDSS Water Resource Planning Models. <br /> <br />Approach: <br /> <br />12.1 Develop Stochastic Model <br /> <br />Primary Responsibility: Ayres <br /> <br />The first subtask will be to develop a stochastic model to synthesize flows at the state line in <br />each basin. This will be accomplished by using natural streamflows as developed in Task 11 <br />for the available concurrent record of the five gages at the bottom of the basins. We will <br />utilize the SAMS tool package for evaluating the data statistics and selecting the appropriate <br />model structure. <br /> <br />The basic structure of the model appropriate for the CRDSS Water Resource Planning <br />applications is expected to be a disaggregation model that preserves the total annual flows in <br />the basin. The focus of this model development will be on the aggregate flows from the five <br />basins in Colorado, each basin's total flow, and flows at each gage site in either the Colorado <br />or Yampa basin. This data will be disaggregated both spatially and seasonally to develop <br /> <br />12 <br />
