What you will learn

Fundamentals of 1-D river modelling using HEC-RAS

Build a 1-D river network

Enter steady and unsteady flow data

Perform steady and unsteady flow runs and learn how to interpret the results

Build a range of hydraulic structures

Run scenarios and calibrate your model

Description

The modelling of flows in rivers using computer simulation packages is primarily undertaken to determine where and when floods will occur. The US Army Corps of Engineers Hydrologic Engineering Center River Analysis Software package (HEC-RAS) is one of the most popular river modelling systems currently in use and is available to download and use for free without the restrictions that some competing software packages currently have. In this step-by-step course I will show you how to build a 1-D river model using HEC-RAS. No prior knowledge of river modelling is required. The course is also designed for those with river modelling experience but who have not yet used HEC-RAS. You will build a river network, add structures to your model and run steady and unsteady flow simulations and then examine scenarios such as simulating climate change and creating levees. There is a course manual to accompany the classes which the user can download and work through independently or in conjunction with the video presentations. This workshop will enable you to gain the basic skills associated with 1-D modelling using HEC-RAS and as such will stand you in good stead whether you study river channel processes in academia or work in the river engineering industry.

I am a Ph.D. scholar affiliated with the Slovak Academy of Sciences in Bratislava. My research project is titled 'Geomorphic Recovery of the Bela River following River Training Interventions.' In my project I am specifically investigating river reaches located within the ecologically sensitive Natura 2000 protected area. I must deal with many challenges related to the analysis of flow hydraulics and sediment transport in these areas. Therefore, I am seeking assistance to acquire advanced modeling skills and methodologies that can be implemented to enhance my research. Akhtar

Very interesting and clearly explained introductory course on 1D river modelling with HEC-RAS. Looking forward to take the course on 2D modelling.

An excellent course for beginners, lectures well done. Gives overall idea of HEC-RAS breaking the ice for those that want or need to start using the USACE program. I highly recommend this course for everyone that do not know how to Use HEC-RAS.

He does a good job explaining the tools and features, really no explanation as to where the data your inputting into these models comes from. I think thats a pretty vital piece of information when building a model from scratch for your own project.

J'ai déjà suivi le cours sur 2d du même enseignant et c'était bien fait. Ce cours aussi a bien commencé et les objectifs sont bien fixés. C'est bien pratique et les sujets sont traités en profondeur.

He only enters the data without giving any explanation why he used this method or chose that option. No explanation for further details.

This course is very good for beginner, In the end of course you will fill that you perform 1-D flood modelling.

It was a great introduction. Gives overall idea of HEC-RAS and some Tips & Tricks. I would also have liked more explanation of the interface and the theory. You showed nothing about RAS mapper.

Only feedback so far is that the screens I get do not always match the tutorial, but it is easy enough for me to find and change the settings to get things to match.

I'm from environmental engineering and it really helped me to understand better the concepts I've learned in my fluid mechanic's course. The application of things like Froude's number and critical/subcritical flow etc...

This is the, top most awesome course that I have taken, and I have no regrets. And I am genuinely intrigued and star struck with the professor who is explaining this course and know doubt he is in control and has a great depth of knowledge on what he is explaining.

Wonderful, educative, and engaging presentation. I loved the overall overview, and background information on what will be needed to construct and run the model.

It was a great introduction. I learned a great deal I only wish the instructor fully explained what each parameter entered meant.
