Displaying the Calculated Hydrograph Data for
Each Subarea and the Entire Watershed
Using the TR-55 Tabular Method for calculating runoff, you can display the
calculated hydrograph data for each subarea and the entire watershed.
After calculating the peak discharge value, you can click the Tabular button to
display the discharges for each subarea per time increment.
For more information about the data that the Tabular button displays, see
Figure 5-4 in Chapter 5, Tabular Hydrograph Method in the TR-55 manual.
The data that is displayed in the Tabular Method Data dialog box is similar to
the sample data shown on the right side of the Figure 5-4 worksheet.
To display the calculated hydrograph data for each subarea and the entire
watershed
1 From the Hydrology menu, choose Runoff ä Tabular to display the TR-55
Tabular Hydrograph Method dialog box.
2 Click Tabular to display the Tabular Method Data dialog box.
The subarea descriptions display in the column on the left side of the dialog
box. The time displays across the top. The individual subarea hydrograph
ordinates are displayed in the middle columns, and the total watershed
hydrograph is displayed across the bottom row.
