calculate the flow is conducted in an open channel
It allows to calculate the flow is conducted in an open channel for the given data, under uniform steady flow. It uses the Manning’s Equation.
The input data are channel bottom and top width (for rectangular channels they era the same value), the slope of the channel the depth and roughness n is the Manning’s coefficient (dimensionless) – values developed through experimentation.
The app can be used in the SI or US units.
