(5) DOCUMENTATION <br />Software documentation (on-line and written) will be an ongoing task throughout CRDSS development. <br />Documentation will be critical to the long-term success of the system and will provide the State with <br />complete information for maintenance and upgrading of the CRDSS. Objectives of the documentation <br />effort are to provide a feedback mechanism early in development, facilitate sharing of software between <br />developers, support system maintenance and future development, and provide basic training materials. <br />APPLICATION SCENARIOS <br />The utility of the CRDSS can be illustrated by describing candidate scenarios for its application. An <br />application is cast in the context of a user accomplishing her/his job in addressing a particular water <br />management issue. To illustrate, three examples are described below: <br /> <br />Scenario Using Spatial Database -Determine Irrigated Acreage <br />The spatial database functions of CRDSS could be used to review one or more of the data sets <br />incorporated into the CRDSS. For example, a State Legislator may request that the DWR determine the <br />irrigated acreage in their district. The DWR engineer can use the Spatial Data Browser to display a map <br />of irrigated acreage at any location in the Colorado River Basin in Colorado. The engineer could display <br />the regional map, select a subpart of the region pertaining to the area of interest, and display the irrigated <br />lands for that area. Total irrigated acreage for the selected area can then be computed and a table of all <br />irrigated acreage and crop types printed out. <br />Scenario on Water Resource Planning -Evaluate Basin Development Proposal <br />The water resource planning model of CRDSS could be used by CWCB personnel to evaluate a <br />proposed water project on a river on the western slope. The CWCB personnel could identify a level of <br />project development that would not adversely impact decreed water rights and that establishes the <br />project's feasibility on a technical and economic basis. Information development actions can be performed <br />using data management and modeling functions accessed through the CRDSS interface. The Map Utility <br />can be used to identify possible locations for development. A development plan can be defined using a <br />spreadsheet utility to compile and edit water rights priorities, amount, and timing. These data can then be <br />
