Provide a brief description of the programGive an overview of the model, including

its capabilities and limitations


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


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

Curve Number, Time of Concentration (Tc), and Output Code (Peak, Hydrograph, Time Analysis, and Hydrograph File)

– Global Output (at least one item selected).


User ResponsibilityUser 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.
