Title: WinTR-55 Small Watershed Hydrology


1
WinTR-55 Small Watershed Hydrology
WinTR-55 Development Team
2
Common Hydrology of Urbanization
3
WinTR-55
DOS
Windows

Tutorial
  • Demonstrate WinTR-55
  • Create WinTR-55 Input File
  • Run WinTR-55
  • View WinTR-55 Output

5
WinTR-55 Capabilities Limitations
  • Maximum Area 25 square miles
  • Watersheds 1-10
  • Tc 0.1 hour ltTc lt 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

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

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
  • Watershedsystem of sub-areas and reaches
  • Sub-areas hydrograph-generating areas
  • Sub-areas -flow into upstream end of stream reach

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)

10
Watershed Example
11
Sub-area Data
  • Drainage Area
  • Runoff Curve Number (RCN) Data
  • Time of Concentration (Tc) Data
  • Channel Reach Data
  • Structure Reach Data

  • Time of Concentration
  • Structure Data
  • Reach Data
  • Buttons
  • Double-click title blocks in grid

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

20
Land Use Details

21
Land Use Summary
  • Convenient summary
  • Display current subarea
  • Summary toggle

22
Custom Curve Number
  • Create Custom CN
  • Pervious curve number
  • Impervious area
  • Impervious area unconnected

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

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
  • gt 10 reaches
  • complex channel or storage routing

25
Reach Data Entry
  • Unique Reach Name (lt 10 characters)
