Course Description

This course is intended for hydrologists, civil engineers, hydraulic engineers, highway engineers and environmental engineers. Someone completing this course 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.

Course Objectives

Upon completion of this course, the participant will be able to:

• Differentiate between laminar & turbulent, steady state & unsteady state, and uniform & non-uniform open channel flow.

• Calculate the hydraulic radius for flow of a specified depth in an open channel with specified cross-sectional shape and size.

• Calculate the Reynolds Number for a specified open channel flow and determine whether the flow will be laminar or turbulent flow.

• Use tables such as the examples given in this course to determine a value for Manning roughness coefficient for flow in a manmade or natural open channel.

• Use the Manning Equation to calculate volumetric flow rate, average velocity, Manning roughness coefficient, or channel bottom slope, if given adequate information about a reach of open channel flow.

• Use the Manning Equation, with an iterative procedure, to calculate normal depth for specified volumetric flow rate, channel bottom slope, channel shape & size, and Manning roughness coefficient for a reach of open channel flow.

• Make Manning Equation calculations in either U.S. units or S.I. units.

• Calculate the Manning roughness coefficient for a natural channel based on descriptive information about the channel.

• Carry out a variety of calculations for full or partially full flow under gravity in a circular pipe.
