WinTR-55 Capabilities & Limitations
Maximum Area 25 square miles Watersheds 1-10 Tc 0.1 hour <Tc < 10
hours Reaches 0-10 Reach Types Channel or Structure Reach Routing Muskingum-Cunge Structure Routing Storage-Indication Structure Types Pipe or Weir Structure Sizes 1-3
04/18/23 TR-55 Update 6
Capabilities & Limitations
Rainfall Depth Default or user-defined
0-50 inches (0-1,270 mm)
Rainfall Distributions NRCS Type I/IA/II/III or
user-defined Rainfall Duration 24-hour Dimensionless Unit Standard peak rate
Hydrograph 484 or user-defined Antecedent Runoff 2 (average)
Condition
04/18/23 TR-55 Update 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)
04/18/23 TR-55 Update 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
04/18/23 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)
04/18/23 TR-55 Update 10

Global Data - Main Window
Storm Data-rainfall depths(how much did it rain?)
Custom Rainfall Distributions-(how was the rain distributed during the storm?)
Dimensionless Unit Hydrograph-(What shape is the hydrograph?)
04/18/23 TR-55 Update 30
Storm Data
NRCS-supplied rainfall depths and distributions for the US states and counties
Edit rainfall depths Design rainfall distribution “Accept” to exit window Changing State-County on
Main Window doesn’t change Storm Data!
Set/edit Storm Data each run!
04/18/23 TR-55 Update 31
Watersheds Outside US
“State” and “County” become“Region” and “Locale”
No NRCS-supplied rainfall data
Must enter rainfall depths and pick distribution
