  1. WinTR-55 Small Watershed Hydrology WinTR-55 Development Team

  2. WinTR-55 Common Hydrology of Urbanization TR-55 Update

  3. WinTR-55 DOS Windows TR-55 Update

  4. Tutorial • Demonstrate WinTR-55 • Create WinTR-55 Input File • Run WinTR-55 • View WinTR-55 Output TR-55 Update

  5. 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 WinTR-55 Capabilities & Limitations TR-55 Update

  6. 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 Capabilities & Limitations 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) 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 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) TR-55 Update

  10. Sub-area 1 Reach 1(storage routing) Sub-area 2 Reach 2 Legend (Reach Routing) Storage Area Sub-Area Inflow Outlet Watershed Example TR-55 Update

  11. 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 TR-55 Update

  12. Getting Started- Welcome to WinTR-55 Window • Start WinTR-55“Return to WinTR55” • New user help • Skip welcome screen TR-55 Update

  13. WinTR-55 Main Window • Input basic project data • Menu • Buttons • Input boxes TR-55 Update

  14. Help • Display introduction • Help for the Main Window • System information • Program version number and date TR-55 Update

  15. WinTR-55 Main Window • New project “File - New” TR-55 Update

  16. Units • English or • Metric TR-55 Update

  17. Main Window-Data Entry • Project Identification Data (User, Project, etc.) • Choose area units • square mile or acres • square km or hectares • Select Dimensionless Unit Hydrograph • Input known project data in the “Sub-area Entry and Summary” • Tc & RCN - direct input TR-55 Update

  18. Project Data • Project Data menu • Land Use Details • Time of Concentration • Structure Data • Reach Data • Buttons • Double-click title blocks in grid TR-55 Update

  19. Land Use Details • Go to land use • right vertical scrollbar • Land Use Category radio button • Area in hydrologic soil column • Maximum 15 land uses per subarea TR-55 Update

  20. Land Use Details • Weighted CN • Accumulated sub-area area TR-55 Update

  21. Land Use Summary • Convenient summary • Display current subarea • Summary toggle TR-55 Update

  22. Custom Curve Number • Create Custom CN • Pervious curve number • % Impervious area • % Impervious area unconnected TR-55 Update

  23. Time of Concentration Details • Enter sub-area flow path segment data • 5 flow segments: 1-sheet flow 2-shallow concentrated2-channel flow • Displays total flow path length • Displays average flow velocity TR-55 Update

  24. Reach Data Entry • Edit stream network • Channel reach or storage (structure) reach • Create channel reach rating table • Use another model (e.g. NRCS WinTR-20) when: • > 10 reaches • complex channel or storage routing TR-55 Update

  25. Reach Data Entry • Unique “Reach Name” (< 10 characters) • Downstream “Receiving Reach” • Channels - channel data • Structure - • Enter structure name • Go to Structure Data Window (Double-click Name) TR-55 Update

  26. Reach Data Plot • Graphical channel rating“Plot” • Line width & color-”Options” TR-55 Update

  27. View Reach Data • schematic “Reach Flow Path” • Detail toggle All Details Overview TR-55 Update

  28. Structure Data • Name • Surface area • Outlet type & size • Structure name correspond to Reach Window name • 1-3 sizes/trials • Complex ratings--use another model (e.g.WinTR-20 or Sites) TR-55 Update

  29. 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?) 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! TR-55 Update
