Civil and Highway designers can check how stormwater flows across their design, using Road Flow. Road Flow uses the TUFLOW 2D Modelling engine integrated into 12d Model to quickly and accurately determine flows and velocities across the design surface.

Problem areas are quickly identified and can be corrected.  Videos showing flow across the surface can be used for presentation to a non-technical audience.

Drainage 2d Tuflow Introduction

This one day course covers the use of Road Flow to model the flow of stormwater across the design surface, to quickly evaluate how stormwater will flow across their design surface. Roadflow uses the world-renowned TUFLOW engine (integrated into 12dModel) to produce a 2d model of the way that water will flow across the design surface.

The designer will quickly see where depth or velocities are unacceptable, or where water over-tops a road crown. Roadflow can be used during the design 12d Model process process, or to model designs from other packages to check for design problems.

Video animation is produced showing changes to water depths during a storm event, these are invaluable when working with a non-technical audience.

Prerequisites: Completion of the “Introduction to 12d Model” is required. By booking a course, you affirm that you meet the requirements for 12d Model training courses. Check on upcoming courses at bottom of page.


Participants will become familiar with the use of 12d Model (and the TUFLOW hydraulic engine integrated into 12d Model) to model stormwater flow across their design surface.
Results of the analysis will be velocity and depth contours and flow arrows, these will have been inspected and changes in flow displayed as the amount and velocity of the water increases. A video will be produced showing inundation of water across the surface.
