   • From the left hand menu, click on the “Download”.  
   • Download the latest version of the program available.
2. Complete: The Introduction to HEC-RAS Directions (distributed by the Professor).
3. Submit: the required information for the laboratory report.  Make sure to name the project file “YourLastName_YourFirstName.”  This will serve as proof that you completed the exercise yourself.
4. Additional Resource(s):
   • Albrook Hydraulics Laboratory. November 17, 2016. “HEC-RAS Tutorials” There are 7 videos that walk through download and installation (~4 min.), an overview (~7:30 min.), and 5 other videos that walk through a problem (~20 – 30 min.)
   • Reference Book: Floodplain Modeling Using HEC-RAS (ISBN-10: 1934493023) but it is strongly encouraged that you check out all of the free resources available online.

Want to explore HEC-RAS more? There are additional resources available from the US Army Corp of Engineers. If you download the “with examples version” of HEC-RAS, there are problems available in the “Application Guide” than you can work through using the data available with the download. Also, check out the “User Manual” for additional support and guidance.

Additionally, there are some training courses available on the Army Corps website. Click “Training Materials” and you will be able to see the courses and material that you can follow along with at your own pace. For example, #352 – Advanced 1D 2D Unsteady Flow Modeling (July 2019) has a mix of slides and examples. When you get to 1.6, you will be able to download the material and try on your own. There are also “Webinars and Tutorials” for free videos, which have data files available also.

Week 15: Review (if needed) and Submission Deadline

The last session will be planned based on the class needs.
