<br />and potential new diversions. The PlFLOW uses data from the South Platte Water Rights <br />Management System (SPWRMS) providing real time and historic point flow computations. <br /> <br />Maurice Hall has completed his dissertation in the Department of Earth Resources at Colorado <br />State University, titled "Simulation of Nitrates in a Regional Subsurface System: Linking <br />Surface Management with Groundwater Quality." He used a study area near Greeley in the <br />South Platte. His work, based on a set of pre-existing models, will provide some important ideas <br />related to the problems with nitrate contamination in the groundwater. <br /> <br />The State of Colorado (CWCB, 1995), has a plan and schedule to develop a statewide "Colorado <br />Water Decision Support System." The development of this system is estimated to cost 5 million <br />dollars and will take approximately 8 years to complete. This project would be an extension to <br />the Colorado River Decision Support System (CRDSS) project. Because of the geology of the <br />western slope, data and models for groundwater were not required for the Colorado River Basin. <br />Therefore, to extend CRDSS to Divisions 1,2, and 3 data and models for groundwater may be <br />needed to realize a "Colorado Water Decision support system" or CWDSS. Both Luis Garcia <br />and Darrell Fontane participated in the CRDSS project for the Western Slope. <br /> <br />John Eckardt's dissertation published at Colorado State University in 1991, titled "Real Time <br />Reservoir Operation Decision Support under the Appropriation Doctrine," focused on identifying <br />and resolving the problems of operating a reservoir system in real-time under the prior <br />appropriation doctrine of water rights. Eckhardt noted that operators suffer more from <br />information overload than lack of information, and showed how a systems approach can help <br />them sort out their options. Based on the latest DSS technology, a framework for real-time <br />reservoir operations decision support was then developed to implement the procedure. <br /> <br />Jeffrey Fredericks (1993), in his dissertation presented at Colorado State University titled <br />"Decision Support System for Conjunctive Stream-Aquifer Management under prior <br />appropriation," prepared a micro-computer based DSS for conjunctive stream-aquifer <br />management under prior appropriation. Almost like Eckhardt, Fredericks accomplished his work <br />through a synthesis of existing technology rather than development of new models. The <br />computer-aided design and drafting package, AUTOCAD, and a raster GIS package for PC's <br />called IDRlSI, were used for preparing and processing grid-based spatial data. To demonstrate <br />the capabilities of the conjunctive stream aquifer managem,ent Decision Support System (DSS), a <br />case study was carried out on a portion of the lower South Platte River Basin in Colorado. <br />Fredericks's framework could conceivably be expanded to include the entire basin, but it is clear <br />that the entire basin is considerably more complex than the test case. <br /> <br />3.0 Scope of this Project <br /> <br />The Colorado Water Resources Research Institute (CWRRI) funded for FY96 a small project to <br />evaluate the status of SAMSON and determine if it could be used as part of a Decision Support <br />System for the South Platte River Basin. The focus was on evaluating the SAMSON model <br />(Stream-Aquifer Model for Management by SimulatiON) in the context of a Decision Support <br />System. The specific objectives of the Project were to: <br /> <br />4 <br />
