<br /> - <br />.' <br /> OOllOo4 <br />.' South Platte Decision Support, 8 <br /> currently set up to run on UNIX work stations in Greeley and Denver, and offers limited access to <br /> PC's via modem. <br /> CROSS is now in its second year of development. Many of the database design, population, and <br /> access decisions that have been made during the first year could be duplicated for a South Platte <br /> DSS. The consumptive use models and water resource planning models within CROSS are being <br /> designed for a modular system. The consumptive use model should, therefore, require only slight <br /> modifications to be used in a South Platte DSS. The water resource planning model for the South <br /> Platte must include surface/groundwater interaction; the CROSS planning model would need to be <br /> modified (or replaced with SAMSON?). <br /> Three major hurdles remain, then: <br /> l. Final development and calibration of a basin-wide, surface/groundwater model, <br /> 2. Development and calibration of an appropriate water quality model, and <br /> 3. Development of the database to support the models. <br /> In order to populate the database for a South Platte DSS, routines similar to those used by . <br /> Fredericks in his dissertation will have to be developed. These routines will read infonnation from <br /> an existing database, perfonn any necessary conversions, and write the infonnation to the South <br /> Platte database. Population of this database is arguably the most critical step in DSS development; <br /> indeed, it has been the Achilles' heel of several modeling efforts.
