Hydraulic Jumps and Supercritical & Non-Uniform Open Channel Flow

COURSE NO: C02-024
PDH CREDIT: 2
Hydraulic Jumps and Supercritical & Non-Uniform Open Channel Flow
Course Highlights

In this online engineering PDH course, the parameter called specific energy will first be used to introduce the concepts of critical, subcritical, and supercritical flow.  Various calculations related to critical, subcritical and supercritical flow conditions will be presented, including hydraulic jump calculations.  The thirteen possible types of gradually varied non-uniform flow surface profiles will then be presented and discussed.  Also, the procedure and equations for step-wise calculation of gradually varied non-uniform surface profiles will be presented and illustrated with examples.

 

Many examples of open channel flow can be approximated as uniform flow allowing the Manning equation to be used.  Non-uniform flow calculations are needed, however, in some open channel flow situations, where the flow is clearly non-uniform.  The concepts of supercritical, subcritical and critical flow, and calculations related to those three regimes of flow, are needed for non-uniform open channel flow analysis and calculations.

 

This 2 PDH online course is intended for hydrologists, civil engineers, hydraulic engineers, highway engineers and environmental engineers.  An attendee of this course will gain knowledge about the meaning of critical, subcritical, and supercritical flow, about basic calculations related to those three types of flow, about the hydraulic jump and basic calculations concerning it, about the classification scheme for types of gradually varied non-uniform flow, and about how to carry out a stepwise calculation of a gradually varied, non-uniform flow surface profile.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Be able to determine the critical depth for a specified volumetric flow rate through a rectangular channel of specified bottom width.
  • Be able to determine the critical slope for a specified volumetric flow rate through an open channel of specified shape, size, & Manning roughness coefficient, with known critical depth.
  • Be able to determine whether a specified volumetric flow rate through an open channel of given shape & size, with known depth of flow will be critical, subcritical or supercritical flow.
  • Be able to calculate the depth of flow after a hydraulic jump if given the depth before the hydraulic jump, the volumetric flow rate and the shape and dimensions of the open channel.
  • Be able to identify which type of surface profile (e.g. M1, M2, M3, S1, S2, S3, etc.) is present in a specified gradually varied flow situation.
  • Be able to carry out a stepwise calculation of the surface profile for a specified, gradually varied, non-uniform open channel flow.
