Course Description


This course is intended primarily for hydrologists, civil engineers, hydraulic engineers, highway engineers and environmental engineers. An attendee of this course will gain knowledge about calculations and installation & measurement guidelines for sharp-crested weirs, as used to measure flow rate in open channels. Upon completing this course, the student will be prepared to study additional open channel flow measurement topics.


Course Objectives


Upon completion of this course, the participant will be able to:
  • Use standard terminology that is used in connection with sharp-crested weirs for open channel flow measurement.
  • Calculate the flow rate over a suppressed rectangular weir for given head over the weir and weir dimensions, using the Kindsvater-Carter equation.
  • Calculate the flow rate over a contracted rectangular weir for given head over the weir and weir dimensions, using the Kindsvater-Carter equation.
  • List the conditions required in order to use the appropriate form of the Francis equation instead of the Kindsvater-Carter equation to calculate the flow rate over a suppressed rectangular weir and over a contracted rectangular weir for given head over the weir and weir dimensions.
  • List the conditions required in order to use the Cone equation, Q = 2.49 H2.48, to calculate the flow rate over a V-notch weir for given head over the weir and weir dimensions.
  • Calculate the flow rate over a V-notch weir for notch angles other than 90o, given head over the weir and weir dimensions, using the Kindsvater-Shen equation.
  • Check on whether required conditions are met and make calculations of flow rate over a cipolleti weir for given head over the weir and weir dimensions.
  • Answer questions about installation and use guidelines for sharp-crested weirs for open channel flow measurement.
