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

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).

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

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

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).

WinTR-20 ConverterReach 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.

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

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.
