  • Designs steady-state water surface profiles for open channels.

  • Helps engineers visualize design alternatives.

  • Exports to Excel spreadsheets, and prints graphical surface profile reports.

  • Handles both subcritical and supercritical flow types.

  • Includes many useful tools for designing weirs, orifices, and underflow gates.

Easy data entry, and good units flexibility. The flexibility of analyzing different channel types is a real plus, and I like being able to customize the channel title for my reports."

Surface Profile Classification

Flow Pro will compute the standard classification for a water surface profile.
The profile classifications are defined below for gradually varied flow in a prismatic channel,
in which the flowrate does not change with the position along the channel.

A graphical representation of each profile classification is shown below.

The letter classification used is as follows:

M: the slope of the channel is mild; such that the flow will be subcritical.
S: the slope of the channel is steep; such that the flow will be supercritical.
H: the channel is horizontal and it's slope is zero.
C: the slope of the channel will produce critical flow.
A: the channel slope is negative (adverse), and increases in elevation in the direction of flow.
Each letter classification also includes a subscript:
1: the actual depth is above both of the reference depths.
2: the actual depth is between the two reference depths.
3: the actual depth is below both of the reference depth.
