Chapter 9 Viewing Results Figure 9-27 Exporting Computed Rating Curves to HEC-DSS As shown in Figure 9-27, to export a computed rating curve to DSS, select the river, reach, and river stations that you want to have exported to the DSS file. Then simply press the Export Rating Curves button to have the program write the data to the DSS file. If your profiles are not in the order from lowest flow to highest flow, turn on the option that says Sort flows in rating curve. This option will ensure that the curve is written in the order of increasing flow rate. The HEC-RAS program computes cumulative storage volumes for each of the water surface profiles. This information can be used for hydrologic routing in a hydrology model such as HEC-HMS or HEC-1. The HEC-RAS program allows the user to write out storage versus volume information to a DSS file. To use this option select the Storage Outflow tab from the Export to DSS window. When this option is selected a window will appear as shown in Figure 9-28. 9-36
