  1. WinTR-20Project Formulation HydrologyComputer Program Overview Presented by: WinTR-20 Development Team

  2. Objectives • Background of the development: WinTR-20 computer program • Provide a brief description of the program • Give an overview of the model, including its capabilities and limitations WinTR-20 Overview March 2009

  3. Background • Technical Release 20 Computer Program for Project Formulation Hydrology (TR-20) was first released in 1965 • Revised in 1982, 1983, and 1986 • Revision in February 1992 • Major revision late 1998 WinTR-20 Overview March 2009

  4. Background (continued) • Major revision in late 1998 - WinTR-20 team was formed. - WinTR-20 team charge was to: 1. Modernize and revise the TR-20 computer software. 2. Upgrade the source code to Visual Basic. 3. Change the philosophy of data input. 4. Provide plots. 5. Windows interface and output post-processor. - First version of Windows based WinTR-20 was released in late September 2004. WinTR-20 Overview March 2009

  5. WinTR-20 New Features • Muskingum-Cunge Channel Routing replaces ATT-KIN • Sub-Area / Reach Routing Concept replaces old Standard Control • Runoff Curve Number (RCN) Calculation Option • Time of Concentration (Tc) Calculation Option WinTR-20 Overview March 2009

  14. WinTR-20 Identifier Window • WinTR-20: Version 1.11 - Input Units Code: - Output Units Code: - Minimum Hydrograph Value: - Watershed Description: WinTR-20 Overview March 2009

  15. Close Window Buttons • Two choices are given on most screens: • Accept Changes (Close) – All data shown will written to the input file. Selecting this accepts the data you’ve entered and returns you to the previous screen. • No Changes (Close) – None of the changes made to items in that window will be written to the input file. Select this to keep the original data and return to the previous screen. WinTR-20 Overview March 2009

  16. Sub-area/Reach Concepts • Watershed - system of sub-areas and reaches • Sub-areas - watersheds that generate runoff - feed into the upstream end of reaches • Reaches or Routing Elements- represent watershed stream flow paths or structures • Channel Routing elements - Stream Reaches • Structure Routing elements - Reservoir/Structure Reaches • Watershed Outlet-final reach(required for all watersheds) WinTR-20 Overview March 2009

  17. Sub-area/Reach Concepts • Watershed- system of sub-areas and reaches • Reaches- represent watershed flow paths (stream channels) or structures • Sub-areas - watersheds that generate runoff WinTR-20 Overview March 2009

  38. Minimum Data Requirements • Data required for a single sub-area run can be entered on the WinTR-20 System Controller/Editor Main Window. These data include: • WinTR-20 Identifier – Input and Output Units Code, Minimum Hydrograph Value, and Watershed Description • Storm Analysis Identifier – Gage Rain Table (Type I, etc.), Gage Antecedent Runoff Condition, and Rainfall Data • Sub-Area Identifier – Reach, Drainage Area, Weighted Curve Number, Time of Concentration (Tc), and Output Code (Peak, Hydrograph, Time Analysis, and Hydrograph File) • Global Output (at least one item selected). WinTR-20 Overview March 2009

  39. User Responsibility • Results from the model can be sensitive to the input data. • It is the user’s responsibility to ensure that all the input data (whether it is actually entered or implied through default values for blank data fields) is appropriate. WinTR-20 Overview March 2009

  40. WinTR-20 web sites • NRCS users may find WinTR-20 by: Contact your state ITS for download • Non-NRCS users may find WinTR-20 at: http://www.wsi.nrcs.usda.gov/products/W2Q/H&H/Tools_Models/WinTR20.html • E-mail questions to: LO-OR-NRCS-TR20@one.usda.gov WinTR-20 Overview March 2009
