Description:

This Excel workbook streamlines uniform open channel flow calculations by automating the time-consuming iterative solution for normal depth required by the Manning equation. It also calculates flow rate and velocity, or required channel slope for specified values of the other open channel flow parameters. The user may select rectangular, trapezoidal, or triangular as the channel cross-sectional shape. The workbook calculates the hydraulic radius and uses the Manning equation in each case.

Equations used: Manning Equation.
