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.
