Content Type: Spreadsheet
For non-uniform open channel flow, the depth of flow varies with distance along the channel. This spreadsheet makes the necessary stepwise calculations and plots the surface profile for user specified channel discharge, upstream and downstream depth, and channel properties.
There are worksheets to make these calculations and plots for a:
i) rectangular channel
ii) trapezoidal channel
iii) triangular channel
Equations used: Manning Equation.
