One Dimensional Hydraulic Modeling with HEC-RAS
Learn 1D hydraulic modeling and one of the most popular software programs in the water resources field!
HEC-RAS workshops can cost over $1,000, and HEC-RAS webinars available online can cost over $100 for just a one-hour lecture. In contrast, this course has lectures, quizzes, exercises, and assignments to help you develop your hydraulic modeling skills at an affordable price!
In addition, I designed this course to equip you with the skills to develop professional HEC-RAS models. Students, civil engineers, hydrologists, and project managers will benefit from this course. Basically, this course is what I wanted when I was learning HEC-RAS because it presents the most important information you need for getting started. It also gives you ways to apply this information. Your time is precious. Don’t waste it trying to read the entire HEC-RAS manual!
In this course, I will teach you how to develop 1D hydraulic models for river and stream studies, FEMA floodplain projects, bridge design, and culvert analysis. I have also included a section on the HEC-RAS Controller, which will allow you to automate tedious modeling tasks.
In addition to lectures and reading material, I have included quizzes and exercises to help you practice your new skills. Finally, the course includes a final project. The final project involves modeling the Santa Ana River’s floodplain. In addition to the required data, I have also provided a report template. This will allow you to show off your skills to potential employers.
This lecture is an overview of hydraulic modeling in HEC-RAS.
This lecture will demonstrate how to install HEC-RAS. You can download HEC-RAS from the Hydrologic Engineering Center's website.
This lecture is a general overview of the steps involved in developing a 1D HEC-RAS model.
Download the attachment and review the file types in HEC-RAS. It is important to know what each file is and how it fits into the general scheme of your project.
