Open Channel Hydraulics II - Sharp-Crested Weirs

Open Channel Hydraulics II - Sharp-Crested Weirs
Course Highlights

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.

Learning Objectives

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

Webinar Registration

Once you have decided on a webinar or multiple webinars, click on “Add to Cart”. At this point, you will need to log in to your account, or register if you don’t have one yet, to complete your purchase. (The Log in/Register links are located at the top right corner of the computer screen.) Following purchase, you will immediately receive two emails: one confirming your registration with a receipt of webinar purchase and the other providing you with instructions on webinar access and completion. Subsequently, you will also receive reminder emails with the same instructions 24 hours as well as 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.

Webinar Access

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 the pesentation as well as listen to and interact with the instructor. Therefore, to get connected, you will need a computer with high-speed internet as well as microphone and speaker 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 download it 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.

Certificate of Completion (PDH Credit)

Following attending the webinar, you need to return to the website and log in to your account to complete and submit the feedback form. Once submitted, we will email you your Certificate of Completion. You can also download it instantly, or at anytime, from your account where all your PDH records are kept for your convenience at all times.

PDH Accredited Webinars (including IA, NE, NY, OH and WI) live interactive webinars are accepted for PDH or CEU credit by all State Licensing Boards (including IA, NE, NY, OH and WI) mandating continuing professional competency, as they are prepared in compliance with the requirements of all State Licensing Boards. For additional details, please refer to your State Requirements.

Our PDH or CEU accredited webinars are developed and conducted by subject matter experts experienced in their field of practice. Our webinars are designed as live interactive web-conferences allowing you the opportunity to fully interact with the instructor at any time during the webinar from the convenience of your home, office or anywhere using your computer or mobile device.

Webinar Cancellation

If you register but you cannot attend due to unforeseen circumstances, we will issue a full refund if you notify us of your cancellation 24 hours in advance. If you must cancel in less than 24 hours, we will exchange it with another webinar of equal value that you select and attend at a date of your convenience. There is no expiration to your purchase so you don’t have to worry.

Group Webinars

If you have seven (7) or more engineers interested in attending the same webinar, we encourage you to enroll in our Group Webinar Program and purchase the one of interest to maximize your savings. Our webinars cover a variety of engineering and ethical topics and are presented by subject matter experts distinguished by their many years of practical engineering experience and academic standings.
