BackgroundBackground
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 20094
Background (continued)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.

Sub-area/Reach ConceptsSub-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)

Sub-area/Reach ConceptsSub-area/Reach Concepts
Reaches - represent watershed flow paths (stream channels) or structures
Watershed - system of sub-areas and reaches
Sub-areas - watersheds that generate runoff

Minimum Data RequirementsMinimum 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
