43. WinTR-20 Basic Input & Output March 2009 43 Checking Data Prior to Running WinTR-20 ● Prior to running WinTR-20, it is useful to view the watershed “Schematic”. ● Under the “View” drop down menu on the Controller/ Editor screen, click on “Schematic”.

44. WinTR-20 Basic Input & Output March 2009 44 Checking Data Prior to Running WinTR-20 ● The Schematic shows how the sub-areas and reaches are configured. ● Make sure that “Legend” and “Labels” under the “View” options are turned on.

45. WinTR-20 Basic Input & Output March 2009 45 Running WinTR-20 ● After the file has been saved, the “Run” option will show in menu bar at the top. ● To run the program, simply click on the “Run”.

46. WinTR-20 Basic Input & Output March 2009 46 WinTR-20 Output- Printed Page File ● Following a successful run, the “Printed Page File” screen comes up. ● For this example, peak discharge and hydrographs were requested for all sub- areas and stream reaches. ● Output can be sent to the printer or to a file from this screen.

47. WinTR-20 Basic Input & Output March 2009 47 WinTR-20 Output- Debug File ● After viewing, the “Printed Page File” there may be other output to view. ● Click View and see if there is a “Debug File”. ● Output can be sent to the printer from this screen.

48. WinTR-20 Basic Input & Output March 2009 48 WinTR-20 Output - Plots ● WinTR-20 also has graphical output capabilities. ● Following a successful run, the “Plots” option can be selected...

49. WinTR-20 Basic Input & Output March 2009 49 WinTR-20 Output - Plots ● In this example, the Hydrograph for Sub- Area 2 100-year storm is requested. ● Note: Hydrograph plots are only available if “Hydrograph Output” has been selected within the individual sub-area/stream reach or as a Global Output.

50. WinTR-20 Basic Input & Output March 2009 50 WinTR-20 Output - Plots ● To view the Hydrograph, click on “Display” button. ● Options include printing, copying, and zooming in and out.

51. WinTR-20 Basic Input & Output March 2009 51 WinTR-20 Output - Plots ● To plot two items on the same graph, select an option (Multiple Storms, Alternate or Location) under Multiple Hydrographs ● For this example (multiple location), a plot of the hydrograph into and out of the storage structure (Reach 1) for the 100- year event is selected.

52. WinTR-20 Basic Input & Output March 2009 52 WinTR-20 Output - Plots To view the multiple Hydrograph plot, click on “Display” button.

53. WinTR-20 Basic Input & Output March 2009 53 Global Output ● Instead of requesting individual output options within each sub-area and stream reach, the user can use the “Global Output” from the main menu.

54. WinTR-20 Basic Input & Output March 2009 54 Global Output ● Global Output allows the user to select the same output for ALL sub- areas and stream reaches at once. ● For this example, hydrographs and peak discharge information will be output for all points in the watershed.

55. WinTR-20 Basic Input & Output March 2009 55 Some Important Considerations: ● Each time a change is made to the input data, the file must be saved before the “Run” option is presented. ● When bringing in an existing file, select “ No Changes (Close) ” to get the “Run” option to appear. ● All data input require a positive entry (i.e. carriage return, tab, or left mouse click in another data box) to be recognized.
