Open Channel Hydraulics III - Sharp-Crested Weirs
PRICE GROUP WEBINAR
Webinar Title: Open Channel Hydraulics III - Sharp-Crested Weirs
Webinar No: C03-203W
PDH Credit: 3
Presenter: Harlan Bengtson, Ph.D., P.E.
Time: From 12:00 PM to 3:00 PM ET
This online engineering PDH live webinar is devoted to the more widely used sharp-crested weir. It places emphasis on the calculations used to measure for flow rate in various types of sharp-crested weirs. It presents guidelines for the installation, measurement and use of sharp-crested weirs in open channels.
A weir is basically an obstruction in an open channel flow path. Weirs are commonly used for measurement of open channel flow rate. A weir functions by causing water to rise above the obstruction in order to flow over it. The height of water above the obstruction correlates with the flow rate, so that measurement of the height of the flowing water above the top of the weir can be used to determine the flow rate through the use of an equation, graph or table. The top of the weir, which is used as the reference level for the height of water flowing over it, is called the crest of the weir. Weirs are typically classified as being either sharp-crested or broad-crested.
This 3 PDH online live webinar is intended primarily for civil, hydraulic, highway, environmental, chemical, mechanical, and industrial engineers, who are interested in learning more about open channel hydraulics.
This PE continuing education live webinar is intended to provide you with the following specific knowledge and skills:
- Familiarizing with standard terminology used in conjunction with sharp-crested weirs for open channel flow measurement
- Applying the Kindsvater-Carter equation to calculate the flow rate over a suppressed rectangular weir for given head over the weir and weir dimensions
- Applying the Kindsvater-Carter equation to calculate the flow rate over a contracted rectangular weir for given head over the weir and weir dimensions
- Knowing the conditions required in order to use the equation, Q = 2.49H2.48, for calculating the flow rate over a V- notch weir for given head over the weir and weir dimensions
- Applying the Kindsvater-Carter equation to calculate the flow rate over a V-notch weir for notch angles other than 90o, given head over the weir and weir dimensions
- Familiarizing with the installation and use guidelines for sharp-crested weirs for open channel flow measurement

Subsequently, you will also receive reminder emails with the same instructions 24 hours and 2 hours prior to your scheduled webinar. You can also download these instructions from your account at anytime.
We recommend that you register for any webinar ahead of time, although you can still register online up to the start time of the webinar. If you need any assistance with last minute webinar registrations, please contact us at 877-322-5800.
From the webinar access and completion instructions that you receive, you will be provided with a link to access the webinar platform from your computer to view and listen in to the webinar. Therefore, to get connected, you will need a computer with high-speed internet as well as microphone and speakers capabilities. We recommend using a headset connected to your computer for enhanced audio quality.
Alternatively, if your computer is not equipped with a microphone and speakers, you need to dial in using a phone line. From the webinar access and completion instructions, you will be also provided with a dial-in number to join the webinar and listen in. Furthermore, you will be provided with a link to download the webinar handout, or you can do directly from you account, in the event you are unable to view the webinar on your computer screen.
Regardless of the connection method used, you will have the opportunity to interact with the instructor at the appropriate times either way. We recommend that you connect to the webinar approximately 10 to 15 minutes prior to the scheduled start time.
Following attending the webinar, you need to return to the CED Engineering website and login to your account to complete and submit your feedback form.
Following submission of your feedback form, we will email you your Certificate of Completion. You can also download your Certificate of Completion instantly, or at anytime, directly from your account. This is where all your PDH records are kept for your convenience at all times.
