Got to move the sand onwards but should have been set up as permanent bypass system when the beach I assume you are talking about was created.
Could be an all time right hander there with a certain famous body board wave continuing to run down the beach without the crazy return groyne they put in.
Lost a wave, got a wave and then the return went in and wave went again.
Such a shame as it is a swell magnet
you'd lose the specified navigable depth in the cut after a short while without that spur groyne, plus permanent systems have not been proven to be able to deal with the weed that you love showing pictures of here as well bakesy. plus the rock shelf a short depth under the sand makes them less efficient (depth of sand that can be sucked up is really important). plus reducing the amount of sand that actually goes past in any way severely affects the northern mandurah beaches.
the city of mandurah is still looking at a permanent system, the government is too, but when you start talking about tens of millions of tax payers dollars to install and operate - justifying it to tax payers from all over the state becomes more difficult. just saying.
i have a bit to do with it through my work, and happy to talk about the system in more detail with anyone who wants to ask, which i've said on here before.
cheers.
