HEC-RAS Modeling Workshop (1.2CEU's)

HEC-RAS Modeling - Training Workshop (1.2 CEUs)

Daily Schedule:

8:00am - Registration
8:30am - Session begins
4:30pm - Adjournment
Breakfast, two refreshment breaks and lunch are provided daily 

This two day workshop provides HEC-RAS Steady Flow River Hydraulics Modeling training. The Hydrologic Engineering Center—River Analysis System (HEC-RAS) is a computer software designed to simulate water surface profiles and velocities for a network of natural and constructed watercourses. HEC-RAS is widely used throughout the world as an industry standard hydraulics program. The lectures and lab sessions will concentrate on teaching and demonstrating principle of hydraulics and hydrology and how to use the software in practical engineering applications. Participants will learn by doing, while using the HEC-RAS software on their own computers. The Software and Documentations are free downloaded from


By participating in this workshop, you will be able to construct a complete HEC-RAS model using the exercises provided in the course. Performance of channel network, bridge and culvert design and analysis will be conducted along with the sample projects. Introduction to flood studies using HEC-RAS will be provided. Participants will gain confidence in applying HEC-RAS to a variety of modeling problems from the lectures and exercises provided. Troubleshooting and how to review, verify and calibrate HEC-RAS models will be provided.

Important Notes:
  1. This course is intended to preliminary users or users who did small practising on Hec-Ras modeling. This course is not intended to advanced users who did so much work using the software.
  2. Unsteady Flow and Water Quality Analysis will not be covered during the course. These topics will be posted separately in the future as third day training.
  3. User Manual, Reference Manual and Application Guide will be the main data sources and will be used during the course.
  4. Certificates will be provided at the end of the course.

Dr. Hesham Zare

Dr. Hesham Zare, P.Eng, M.Sc. has a Ph.D. in Hydrotechnical Engineering from Western Ontario University, London, Ontario, Canada.

Dr. Zare has served as a hydrotechnical and water resources engineer at Golder Associates Ltd, Manitoba Water Stewardship and Alberta Environment and Sustainable Resources Development.

Dr. Zare has over 15 years of experience in hydrotechnical and water resources engineering, hydraulic structure design, teaching, research and consulting in Canada and overseas.

Dr. Zare has designed and delivered many hydraulic and water resources courses and workshops which are very well received by practitioners engineers in Canada and globally. Currently he is a water management projects engineer with Government of Alberta, Edmonton, Alberta. His duties include revision of hydrotechnical and water resources design including hydraulic infrastructures, stormwater management design, flood mitigation and flood mapping, open channel design, slope stability, dam safety review, erosion protection using gabions and rip rap, stabilization of unstable slopes, flood frequency analysis, watersheds and runoff design, etc.

Dr. Zare is a former post doctoral fellow at University of Manitoba, Winnipeg, Manitoba, Canada, and a former assistant professor at Assiut University, Assiut, Egypt.

Dr. Zare is specialized in experimental and numerical modeling for solving sophisticated hydrotechnical engineering problems with respect to erosion protection, hydraulic infrastructures and water resources. He has been rewarded Golder Keffer Medal from Canadian Society of Civil Engineering for the best hydrotechnical research in 2007.

Dr. Zare authored a number of technical papers and delivered numerous internal and external workshops on various Hydrotechnical, Water Resources and Municipal Engineering topics. Dr. Zare has been involved in a number of projects in Canada and overseas, such as stormwater management, erosion protection, flood mitigation, sediment transport, hydraulic infrastructure design, dam safety review, spillways, bridges scour and design, culverts design, irrigation networks, water balance, water supply and many other civil engineering projects in terms of design and construction.

Education @ Your Desk. A Live Webinar Class means that you will attend the class via the web using your computer. There are scheduled breaks for coffee and lunch. You use a microphone, headset, or your phone and are able to interact with the instructor and other students while following notes while watching the presentation slides online just as you would in a live classroom. Notes are posted online. For an extra cost a hard copy can be requested.

The virtual classroom is becoming more and more popular, and we have a lot of experience teaching in this format. The only real difference between a live in-class and live via webinar is where you sit and what you look at. You can learn from the comfort of your own home or office. You pay less for the live webinar format than you would for the in-class format, and you do not have to travel to another city to attend the class. Please contact us at gic@gic-edu.com for Special Group & Corporate Rates for one or more participants.

We could offer any of our courses at a location of your choice and customized contents according to your needs, please contact us at : inhouse@gic-edu.com or click here  to submit an online request.
