1. WinTR-20 Data Converter May 2015 1 WinTR-20 Project Formulation Hydrology Converting Old TR-20 Input Files to New WinTR-20 Format Presented by: WinTR-20 Development Team

2. WinTR-20 Data Converter May 2015 2 WinTR-20 Data Converter The data converter subprogram is within the new WinTR-20 editor. Converts most items in the old TR-20 input data set (Version dated 1983 and later). The data can be run in the present WinTR-20 format.

3. WinTR-20 Data Converter May 2015 3 WinTR-20 Data Converter (continued) Some features in the old TR-20 program are not used in the new WinTR-20 and will not translate. These features will be ignored during the conversion: - Runoff Option in Rainfall Distribution Table - IPEAKS (intermediate peak output) - Multiple time increments (new WinTR-20 will take care of this automatically).

4. WinTR-20 Data Converter May 2015 4 WinTR-20 Converter Output Option Considerations The output options used in the Old TR- 20 input files translate over to the new version. The user could revise the output parameters in the new data file: - Global Output - Sub-Area or Reach record

5. WinTR-20 Data Converter May 2015 5 WinTR-20 Converter Reach Routing Considerations Reach routing has been revised in the new program, the user will have to input additional data. The routine in the new WinTR-20 (Muskingum- Cunge) requires: - Elevation - Discharge - End Area - Top Width - E.G. Slope tables for ALL reach routing

6. WinTR-20 Data Converter May 2015 6 WinTR-20 Converter Reach Routing Considerations (continued) There is no provision for parametric routing (i.e. the “X” and “m” option with the old TR-20 ATT-KIN method) in the new version. Any reach section using “X” and “m” in the Old data must have a complete cross section rating table developed (Elevation, Discharge, End Area, Top Width, and E.G. Slope).

7. WinTR-20 Data Converter May 2015 7 WinTR-20 Converter Reach Routing Considerations (continued) If Old TR-20 data set had “XSECTN” tables: –Converter program will calculate the top width from the old TR-20 “XSECTN” table data. –User only has to add the energy grade (E.G.) slope to the rating table.

9. WinTR-20 Data Converter May 2015 9 WinTR-20 Converter Example Double click on WinTR-20 icon. WinTR-20 System Controller / Editor Window will pop up. Click on “Convert old Data” from the “File” pull down menu.

10. WinTR-20 Data Converter May 2015 10 WinTR-20 Converter Example (continued) Select Old TR-20 data file to convert (Example: A1.dat)

11. WinTR-20 Data Converter May 2015 WinTR-20 Converter Example (Continued) After Old TR-20 data file selected and converted – WinTR-20 Identifier window will appear. You may make changes to: - Min. Hydrograph Values: - Watershed Description: Click “Accept Changes” if changes were made, otherwise click “No Changes (Close)” to close this window. 11

12. WinTR-20 Data Converter May 2015 12 WinTR-20 Converter Example (continued) WinTR-20 System Controller / Editor Window will appear. Select “Stream Cross Section:” to add the missing “E.G. Slope”.

13. WinTR-20 Data Converter May 2015 13 WinTR-20 Converter Example (continued) Select “Stream Cross Section - Xsec 1” from pull down menu. Cross Section data will appear. “Top Width” values – calculated automatically from old TR-20 data.

14. WinTR-20 Data Converter May 2015 14 WinTR-20 Converter Example (continued) To enter the missing “E.G. Slope”: –Click on the line from the table; –Data appears; –Enter “E.G. Slope”; Click on “Display Data” button to view Cross Section plot. Click on “Accept Changes (Close)” button to close this window.

15. WinTR-20 Data Converter May 2015 15 WinTR-20 Converter Example (continued) Peak Output and Hydrograph Output for “Sub-Area” and “Reach” – click on “Global Output:”. “Global Output” Window will appear. At least one item on this window needs to be selected (either Yes or any number entered).

16. WinTR-20 Data Converter May 2015 16 WinTR-20 Converter Example (continued) The User can enter or leave blank as default –Hydrograph Print Precision: –Minimum Hydrograph Display Flow: –Print Time Increment: For Peak Output and Hydrograph Output for “Sub-Area” and “Reach” – check “Yes” Click on “Accept Changes (Close)” button to close this window.

17. WinTR-20 Data Converter May 2015 17 WinTR-20 Converter Example (continued) Save new WinTR-20 data – select “Save As” from the “File” drop down menu. Give a new file name with “.inp” extension. Click “Save” to continue.

18. WinTR-20 Data Converter May 2015 18 WinTR-20 Converter Example (continued) To view the schematic - select “Schematic” from the “View” drop down menu. If the schematic looks OKAY! – exit the schematic window (If Diverts were used check them closely).

19. WinTR-20 Data Converter May 2015 19 WinTR-20 Converter Example (continued) To view the Input File - select “Input File” from the “View” drop down menu. Click “Close” button to exit this window.

20. WinTR-20 Data Converter May 2015 20 WinTR-20 Converter Example (continued) To perform the calculation – select “Run” from the main menu. After a successful run – the WinTR-20 Printed Page File will appear. You are Done!
