What is Manning Formula?

The Manning Formula, also known as the Manning equation, is a widely used empirical formula for calculating the flow of water in open channels. It relates the flow rate, channel shape, roughness, and slope to determine the velocity and discharge of the flow. The formula is named after the Irish engineer Robert Manning, who developed it in the 19th century.
