Open Channel Hydraulics II - Non-Uniform Flow
PRICE GROUP WEBINAR
Webinar Title: Open Channel Hydraulics II - Non-Uniform Flow
Webinar No: C03-201W
PDH Credit: 3
Presenter: Harlan Bengtson, PhD, P.E.
Time: From 12:00 PM to 3:00 PM ET
This online engineering PDH live webinar presents the parameter “specific energy” which will first be used to introduce the concepts of critical, subcritical and supercritical flow. It also presents various calculations related to critical, subcritical and supercritical flow, including hydraulic jump calculations. It discusses the thirteen possible types of gradually varied non-uniform flow surface profiles. It illustrates the procedure and equations for step-wise calculation of gradually varied non-uniform surface profiles through the use of examples.
Many examples of open channel flow can be approximated as uniform flow allowing the use of the Manning equation for calculations. However, non-uniform flow calculations are needed in some open channel flow situations, in which the flow is clearly non-uniform. The concepts of supercritical, subcritical and critical flow, along with calculations related to those three flow regimes are need for non-uniform open channel flow analysis and calculations.
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:
- Determining the critical depth for a specified volumetric flow rate through a rectangular channel of specified bottom width
- Determining the critical slope for a specified volumetric flow rate through an open channel of specified shape, size, and Manning roughness coefficient, with known critical depth
- Determining 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
- Calculating the depth of flow after a hydraulic jump if given the depth of flow before the hydraulic jump, the volumetric flow rate and the shape and dimensions of the open channel.
- Identifying which type of surface profile (e.g. M1, M2, M3, S1, S2, S3, etc.) is present in a specified gradually varied flow situation
- Performing stepwise calculation of the surface profile for a specified gradually varied, non-uniform open channel flow

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 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 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.
