If using discharge-frequency, specify a stage-discharge relationship. You'll need to specify a stage-discharge function to accompany each flow-frequency function. Specify with a series of coordinates of flow and distribution of stage. To create a new stage-discharge relationship:

  1. From the Study Tree, under Stage Transform Functions, right-click on Stage-Discharge Functions and select the create new option. 
    Stage-Discharge Functions shortcut command options for creating or importing relationships.
  2. Enter the name for the function and a description (optional, but recommended). 
  3. Select the Distribution Type from the options: 
    • Deterministic (default selection)
    • Uniform
    • Normal
    • Triangular
    • LogNormal
  4. Enter the stage-discharge function coordinates with the specification of the distribution of stages for a given flow. Be sure to include the zero flow-invert stage coordinate.

  5. Click Save and Close to create the stage transform function.
