7. Minimum Data Requirements
Single sub-area run data
WinTR-55 Main Window
Project Identification Data
User, Project, Subtitle, State & County
Sub-areas are expressed in:
Acres or Square Miles
Dimensionless Unit Hydrograph
Rainfall Storm Data
Sub-area Data (Name, flows to reach/outlet, area, weighted curve number, & time of concentration)

8. WinTR-55 Sub-area/Reach Concepts
Watershed: system of sub-areas and reaches
Sub-areas: hydrograph-generating areas
Sub-areas - flow into upstream end of stream reach

TR-55 Update

9. WinTR-55 Sub-area/Reach Concepts
Reaches - represent watershed stream flow paths
Reaches or Routing Elements - 2 types
Channel routing elements - Stream Reach
Storage routing elements - Reservoir/Structure Reach
“Outlet” -final reach (required for all watersheds)
