E – 1113 Manning Equation – Open Channel Flow using Excel

$100.00

The Manning equation is a widely used empirical equation for uniform open channel flow of water. It provides a relationship among several open channel flow parameters of interest: flow rate or average velocity, bottom slope of the channel, cross-sectional area of flow, wetted perimeter, and Manning roughness coefficient for the channel. Open channel flow takes place in natural channels like rivers and streams, as well as in manmade channels like those used to transport wastewater and in circular sewers flowing partially full.
The main topic of this course is uniform open channel flow, in which the channel slope, water velocity and water depth remain constant. This includes calculations with the Manning equation and the use of Excel spreadsheets for those calculations.

This course is intended for hydrologists, civil engineers, hydraulic engineers, highway engineers and environmental engineers. After completing this course you will have knowledge about the basic nature of flow in open channels and the common ways of classifying open channel flow (laminar or turbulent, steady state or unsteady state, uniform or non-uniform, and critical, subcritical or supercritical). Practice in the use of the Manning equation for a variety of uniform open channel flow calculations will be gained through several worked examples.
