Course: 6th HEC-RAS Water Modelling 1D+2D

Latest version! Hydrologic Engineering Centres-River Analysis System (HEC-RAS)

HEC-RAS is recognised globally as an industry standard hydraulic modelling program and is available for use without charge. Using the latest version, these courses cover basic, intermediate and advanced levels across both 1D and 2D, and gives you access to select HEC-RAS experts who are BETA testers and work in the industry.

You can choose from 3 options in this HEC-RAS training:
2-day (Mon-Tues) 1D only
3-day (Wed-Fri) 2D only
5-day (Mon-Fri) 1D + 2D
Note: The 2D course assumes a basic understanding of 1D.

HEC-RAS 5.0.4 contains many key new features for editing both 1D and 2D data sets, much faster computations, the new 64 bit RAS Mapper can handle much larger terrain data sets and there are improvements to the solution for some settings. HEC GEO-RAS and other third party utilities are no longer needed to create 1D model elements! Come learn these new HEC-RAS features in this combined 1D and 2D training opportunity.

Date: Monday, 4 June 2018 - Friday, 8 June 2018

Location: SYDNEY: Novotel Sydney on Darling Harbour

HEC-RAS is recognised as an industry standard hydraulic modelling program that is widely used throughout the world. This training uses the latest Version of HEC-RAS, available for free download from the US Army Corps of Engineers, who author and support this software. The new version includes two-dimensional floodplain modelling, unsteady sediment transport, bank erosion, water quality, and the RAS Mapper GIS interface.


Course attendees will learn to build, run, and animate flood models using the free HEC-RAS software: See the following two remarkable videos of HEC-RAS Models:
