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) 4/17/2018 TR-55 Update

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 4/17/2018 TR-55 Update

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) 4/17/2018 TR-55 Update

Reach 1 (storage routing) Watershed Example Sub-area 1 Reach 1 (storage routing) Sub-area 2 Reach 2 (Reach Routing) Storage Area Sub-Area Inflow Legend Outlet 4/17/2018 TR-55 Update

Sub-area Data Drainage Area Runoff Curve Number (RCN) Data Time of Concentration (Tc) Data Channel Reach Data Structure Reach Data Design Storm Amounts and Distribution NOTE: RCN and Tc may be directly entered on WinTR-55 Main Window 4/17/2018 TR-55 Update
