Sand bypass and transfer systems around Australia
In September 2019, I started putting together a series of maps showing sand bypass and transfer systems. Working my way around Australia from east coast to west, I posted each map on LinkedIn and invited input from peers, other professionals and academics.
My goal was to create a resource that pooled all our knowledge. I envisaged a final map that could be shared by everyone and add value across the industry by encouraging companies and councils to consider a broad range of options for their next project.
The response was terrific and, today, we are delivering the finished product: an Australia-wide sand bypass and transfer systems map.
Download the maps
I have made these maps available for download in high resolution and I encourage anyone to print out a copy and put it up in their office for quick reference.
- Australia-wide sand bypass and transfer systems map
- Australia-wide sand bypass and transfer systems quick guide (without map)
- South east Qld and northern NSW sand bypass and transfer systems map
- Adelaide to Sydney sand bypass and transfer systems map
- Western Australia sand bypass and transfer systems map
I hope to keep these assests updated every two years, so they’ll always be able to offer a pretty accurate picture of sand bypass and transfer systems around the country.
Sharing the learnings
I’ve published a longer blog on LinkedIn that looks in more detail at my learnings from these maps, including some useful categorisations around how sand is collected and discharged.
If you have a potential project on the radar, I recommend reading that blog.
To re-publish just the big picture here, however:
- There are more than 35 regular sand bypass and transfer systems operating Australia wide.
- More than 3,600,000 m3 of sand is shifted annually through these systems.
- West Australia (14) and south-east Queensland (9) have the most systems, followed closely by Victoria (7).
Criteria for inclusion
At this stage, I think it probably is just worth re-mentioning here my criteria for including a system on the map.
The criteria I adopted were:
- Material is sand
- Sand is placed on shore or in surf zone for beach nourishment
- >10,000m3 is relocated on an annual or frequent basis (not ad hoc).
Naturally, there are many other small and large systems and locations where sand is relocated on an ad-hoc basis, but for the purposes of clarity it made sense to devise a framework like the above.
Maps by region
For those who want to concentrate more closely on just one of the areas that make up the national map, here’s a little more detail on each below – plus links to the original LinkedIn posts if you want to read people’s original feedback.
South east Qld and northern NSW
This one was first cab off the rank. As I noted at the time, most industry people I’d chatted to in south east Queensland and northern NSW knew of the Tweed River Entrance Sand Bypassing Project and the Gold Coast Seaway.
But some of the other nine sand bypass-transfer systems operating annually between Noosa and Newcastle are less familiar.
Adelaide to Sydney
Next up, we worked on the southern coastline. Again, I got a lot of useful feedback and questions around what we did and didn’t include and a few new pieces of information eventually found their way onto the finished map.
Finally, we put together the Western Australia coast line map.
As before, industry peers were generous with their time and input, opening up the conversation to colleagues, referencing historical documents for further context and helping me to clarify my objectives.
Get in touch
As I’ve mentioned throughout, these maps are intended to show the sand bypass and transfer systems that are currently in place and which meet my criteria for inclusion.
