Open Channel Hydraulics I - The Manning Equation
PRICE GROUP WEBINAR
Webinar Title: Open Channel Hydraulics I - The Manning Equation
Webinar No: C03-205W
PDH Credit: 3
Presenter: Harlan Bengtson, PhD, P.E.
Time: From 1:00 PM to 4:00 PM ET
This online engineering PDH live webinar focuses on the basic nature of flow in open channels and common ways of classifying open channel flow (laminar or turbulent, steady state or unsteady state, uniform or non-uniform, and critical, subcritical or supercritical). It presents several worked examples to gain practice in the use of the Manning equation for a variety of uniform open channel flow calculations.
Flow of water may take place either as open channel flow or pressure flow. Pressure flow takes place in a closed conduit such as a pipe, and pressure is the primary driving force for the flow. For open channel flow, on the other hand, the flowing liquid has a free surface that is at atmospheric pressure and the driving force is gravity. Open channel flow takes place in natural channels like rivers and streams. It also occurs in manmade channels such as those used to transport wastewater or irrigation water and in circular sewers flowing partially full.
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:
- Understanding the difference between laminar and turbulent flow, steady state and unsteady state, as well as uniform and non-uniform open channel flow
- Calculating the hydraulic radius for flow of specified depth in an open channel with specified cross-sectional shape and size
- Calculating the Reynolds number for a specified open channel flow and determine whether the flow is laminar or turbulent flow
- Determining a value for the Manning roughness coefficient for flow in manmade or natural channels using the example tables provided in this course
- Using the Manning equation to calculate volumetric flow rate, average velocity, Manning roughness coefficient, or channel bottom slope, if given adequate information about a reach of an open channel
- Using the Manning equation with an iterative procedure to calculate normal depth for a specified volumetric flow rate, channel bottom slope, channel shape and size, and Manning roughness coefficient for a reach of open channel flow
- Performing calculations for full or partial full flow under gravity in a circular pipe

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.
