Channel Design:  
   
   
Velocity (V)
  • Calculate the velocity (V) of uniform flow in an open channel.
Flow (Q)
  • Calculate the flow volume (Q) of uniform flow in an open channel.
Flow Depth (d)
  • Calculate the depth (d) of uniform flow in an open channel.
Critical Depth (dc)
  • Calculate the critical depth (dc) for a flow volume (Q) for an open channel cross section shape.
Channel Bend Depth
  • Calculate the difference in water surface elevations (channel depth) between the inner and outer banks of a bend in an open channel.
Froude No. - Rectangular
  • Calculate the Froude number for an open channel with a rectangular cross section.
Froude No. - Other
  • Calculate the Froude number for any open channel.
Rectangular Weir
