Purpose

Hydraulic characteristics for flow at various normal depths

Three different cross-sections

  1. Circular
  2. Provide diameter, bottom slope or hyd gradient, manning's n

  3. Rectangular Closed Top
  4. Provide width, height, longitudinal bottom slope or hydraulic gradient, manning's n

  5. Triangular Open Top
  6. Provide height at maximum depth, side slopes, longitudinal bottom slope or hyd gradient, manning's n

Results

  1. Froude Number
  2. Flowrate
  3. Velocity
  4. Shear Stress
  5. Top Width
