<br />1. General Modification Description <br /> <br />The Stream Hydraulics Graphics Package has been modified so that it <br /> <br /> <br />will now be able to plot GEDA input data and output results in the same <br /> <br /> <br />way that it does for the HEC-2 data. For general instructions on how to <br /> <br /> <br />run the program and change its options, the draft copy of the users <br /> <br /> <br />manual is being provided. Several new capabil,ities were added to the <br /> <br /> <br />graphics package that are not mentioned in the draft copy of the users <br /> <br /> <br />manual, but will be explained in an addendum to the graphics users manual. <br /> <br />The major change or addition to the graphics package. is the additional <br />capability to plot any of the variables stored on tape 95 against each other. <br />The use of cross hairs to window on the data interactively has been added <br />as an added option to the program. The graphics package will now generate <br />three types of plots; cross section type plots. profile type plots. and <br />rating curve type plots. <br /> <br />The graphics package is primarily being used on the Boeing Computer <br />Services (BCS) system and the Lawrence Berkeley Laboratory (LBL) computer <br />system. The computer being used on both systems is the CDC 7600. The <br />BCS system is providing both interactive and batch graphics, while LBL <br />is only able to provide efficient batch graphics. <br /> <br />The modifications done to the graphics program were developed by <br />Alfredo E. Montalvo of the Hydrologic Engineering Center (HEC). <br /> <br />1 <br />
