GRAPH - This provides graphical displays for both the input and output values. One screen <br />? <br />can display up to three graphs. Line plots and bar charts are available. The user can select the <br />graphs to be displayed, and combinations of graphs can be saved as "scripts" for later access of <br />common graph combinations. The graphs display 3 years of data; the most recent 12-month <br />history and the 24-month forecast. Graphs of input data can be graphically edited and the <br />model can be re-run. The graphs will then display both the results of the previous and current <br />runs. The user can also have exact numerical values displayed for selected points on the graphs. <br /> <br />IMAGE - This provides a schematic of the Colorado River basin and access to physical <br />? <br />characteristics of the reservoirs. <br /> <br />QUIT - This quits the program. <br />? <br /> <br />ESCAPE - This moves back one step in the menu structure. <br />? <br /> <br />RUN - This executes the 24MSM. <br />? <br /> <br />PRINT - This provides for hard copy of graphical or text information. <br />? <br />Not all of the options in the 24MSI are implemented, and there are some minor bugs in the GUI that will <br />lock up the system. The 24MSM input files are read by the 24MSI. The 24MSI understands the syntax <br />of the file and can replace certain blocks of input data that are related to the parameters that the user <br />interactively changes. The original and edited files can be saved. Once the input has been changed, the <br />24MSM must be run to simulate those changes. The main input file for the 24MSM is very similar to the <br />input file for the CRSM. <br />Based upon review of the models and discussions with the State, a workstation version of the 24MSM <br />model was implemented in the CRDSS, and a GUI (CRSMI) was developed for the model. The GUI <br />provides the basic functionality of the 24MSI. The general look and feel of the current 24MSI is <br />maintained in the CRSMI. Mockups of screen displays were developed and reviewed in coordination <br />with the USBR and the State, prior to coding the GUI. <br />Menu items were provided for the eight major buttons available in the 24MSI. All menu selections <br />available in the 24MSI are identical in the CRSMI. Communication with Brad Vickers and Terry Fulp <br />identified all menu items in the 24MSI that were not functional. In the previous task memorandum for <br />this task, it was proposed that all non-functional items be eliminated from the CRDSS version. However, <br />later discussion identified that having different menus in the CRSMI and 24MSI could result in <br />confusion if someone using the CRSMI attempted to communicate with USBR personnel using the <br />24MSI. Therefore, for compatibility the menu items that were not functional in the 24MSI were also <br />included in CRSMI. If a user selects one of these menu items in the CRSMI, a message appears <br />describing that this selection is provided for compatibility purposes only and is not functional. <br />The only functionality not provided in the CRSMI that is available in the 24MSI is the ability to <br />dynamically change reservoir control parameters, such as releases, by modifying the graph using the <br />mouse. In the CRSMI, all editing of input values for the graphics screen must be made using a <br />spreadsheet-like form. However, the graphic display capability provided in the CRSMI is more general <br />and flexible as compared to the 24MSI. <br />3 <br />A275 01.09.95 1.13-1 Fontane <br />
