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.
