June 17th Web Meeting Recording:
Understanding the Importance of Hydraulic Controls and Mesh Resolution in 2D Hydraulic Modeling
Hydraulic modelers,
Thanks to all who could participate in today's web meeting, we greatly appreciated the participation and amount of questions. If you missed it, just click the 'Watch Now' image to watch the recording through Adobe Connect. The presentation slides can be downloaded from the FileShare pod within the Adobe web room. If we did not get to your question, please reach out to Laura or I directly. Otherwise, we will try to address many of these topics in the next webinar.
In this webinar Scott Hogan gave a presentation on 2D modeling mesh resolution and hydraulic controls. The presentation uses a case study to compare the results of different mesh resolutions with measured data, including the use breaklines to represent hydraulic controls and the differences between SRH-2D and HEC-RAS 2D.

Schedule NHI Training Sessions
 |
|
|
Virtual Training Sessions . The online 2D modeling course (NHI 135095V) is available and has been taught numerous times in the past six months. Additional courses get scheduled based on host requests and often have public seats available, but they go quick. To review the currently scheduled courses, just click on the Online Training graphic for more information and then click 'View Sessions' for registration options.You may consider hosting a course if the availability doesn't meet your needs. Please feel free to contact Scott Hogan with questions.
Please note that this is the normal 3-day 135095 in-person course, modified to a 4-day course for online delivery.

Download a FREE copy of the SMS Graphical User Interface and SRH-2D.
Once the software is installed, go to the Menu-Help-Register. Select 'Request a license', which takes you to the Aquaveo page. The 'Request Community' option is free and does not require a license code. All DOTs and FHWA employees should select the Govt' License option.
Reviewers License: Anyone who reviews models rather than develop them, can request a free ‘pro’ version of SMS from Aquaveo. Before requesting a license, reviewers must complete the form at the following link and submit it to Aquaveo. www.aquaveo.com/regulatory-review
