Popular Adelaide beach disappearing under review tide

Sand is rapidly disappearing from popular Henley Beach as a government review stalls replenishment action, with Henley Surf Life Saving Club forced to shovel sand to safely drive rescue vehicles across its access ramp.

Numerous access staircases were closed last year as sand fell away to create a dangerous drop from bottom steps, while some days there is no beach left in some sections for walkers or dogs.

Henley Surf Life Saving Club vice president Lennie Hitch said some life members have never seen their beachfront so depleted, with sand washed away from the sea wall now exposing the old Henley pool’s footings and blue paint.

“This year there has been tremendous erosion of the sand out the front of the Henley Surf Life Saving Club, to the point that the ramp we use to get emergency vehicles on to the beach often has a deep drop at the end of it that our volunteers physically need to fill in,” Hitch said.

“Besides not being able to easily patrol the beach, the lack of sand has also exposed the old footing of the ocean pool that was beside the club, posing a danger to people walking along the beach as well as our Nippers who train there.”

When the State Government was elected last year it scrapped a $38.9 million sand replenishment pipeline plan designed to return long-shore sand drift from northern beaches like Semaphore and Largs Bay, back to Henley Beach South, Henley Beach and West Beach.

Port Adelaide MP and Environment Minister Susan Close declared a conflict of interest after a new scientific review of options was announced, and the review is now being overseen by Attorney-General Kyam Maher.

Hitch called for urgent action to replenish sand while the review is underway, fearing the stretch of beach could be lost.

“We are worried that if no sand replenishment happens while we await the outcome of yet another review into the problem then the beach, which is now unusable at normal high tides, will totally disappear over the coming winter,” Hitch said.

“The lack of sand isn’t an environmental problem. It stems from the boat ramps and breakwaters built to the south of us that interrupt the natural flow of water.

“This is an engineered problem that can’t be rectified, it can only be managed by replenishing sand along the coast north of Glenelg, like they do on the beaches to the south of Glenelg.”

Decades of reviews have been conducted about the drift of sand at Adelaide beaches, with an underground pipeline operating since 2013 between Kingston Park and Glenelg to recycle sand to rebuild southern Adelaide beaches and dunes.

Charles Sturt ward councillor and local resident Kenzie van den Nieuwelaar said a groundswell of concerned locals are calling on the State Government to take urgent action as it conducts “yet another review that could mean two years until something happens”.

She said some days there is barely any dry beach for “morning walkers (or dogs) to enjoy” and this “is a moment in time that if we don’t do something now it’s going to be too late”.

“Just do something, do something in the meantime… in the absence of a long-term solution we need short-term replenishment and nourishment,” she said.

“We have a lot of passionate, concerned, knowledgeable people living down here who are seeing what’s happening,” van den Nieuwelaar said, adding that she has lived in the area for 30 years and never seen the beach so depleted.

Colton Liberal MP Matt Cowdrey has more than 1000 signatures on a petition calling for immediate action to “rectify the unsafe access issues at Henley South and Henley Beach, and to outline and fund a long-term plan for beach management”.

He said a pipeline to deliver a slurry of sand to depleted beaches worked at Noosa and the Gold Coast in Queensland and there was previously a funded plan to install the same to rectify the current problem by the former Liberal Government.

“This issue has been going on for nearly 20 years, we’ve had review after review after review, there was a solution in place,” Cowdrey said, adding that the problem was again in limbo and he is not wedded to a particular solution.

“If it isn’t dealt with it is going to get worse, and worse quickly.

“It’s not just the impact it will have on local residents it’s the economic impact on that stretch of beach on local traders on one of our most popular beaches.”

Department for Environment and Water Coast and Marine Manager Murray Townsend said the State Government’s autumn beach replenishment program will include Henley Beach and that “numerous minor storms during winter took sand off Henley Beach. Some of that sand returned from the nearshore sand bars over summer”.

“The SA Government has committed to matching the rate of sand drift from West Beach while the independent review of Adelaide’s managed beaches is conducted. This averages 100,000 cubic metres per year,” he said.

“The department replenished West Beach with 50,000 cubic metres of sand in spring 2022 and will add another 50,000 cubic metres in autumn 2023 to meet the commitment. This will happen during autumn to minimise disruption to beachgoers during the busy summer period and to nesting shorebirds at the Torrens Outlet.”

Townsend said the Independent Advisory Panel established in November last year has six members and met for the first time in December 2022, the scientific review is due to be completed by the end of 2023 and its recommendations sent to the Attorney-General for consideration.

The Coast Protection Board and South Australian Government have been actively managing Adelaide’s beaches, including replenishing areas with sand from other parts of the beach and external sources for 50 years, he said.

This has included trucking sand along the beach or via roads, or from other parts of the coastline, Townsend said, adding that structures have been built where replenishment would not manage the issue.

What a sad state of affairs our metropolitan coast line is becoming.
One of the great things about Adelaide, and something we under-sell on and lack real promotion about, is that the metropolitan coastline is beaches. You're never too far from a beach in Adelaide. How has this never been a real promotional item for Tourism SA?

Glenelg, West Beach, Henley Beach..what other beaches are disappearing?
What can be done to save them permanently, instead of the annual sand carting eyesore that happens?
Would break waters off the coast help mitigate the loss? Would a redesign of the breakwater at Glenelg, and boat ramps/break waters elsewhere along the coast that's contributing to this disastrous situation be feasible? Personally I think no cost should be spared. The beaches of Adelaide's coastline are a tremendous natural asset that should be saved.

The former government's pipeline project would have have worked. Unfortunately the new government scrapped it so they could undertake yet another review, stalling any real action and progress on the worsening problem. Expect to see more trucks on our beaches in the coming years.

Agree with you on the lack of promotion of our wonderful metropolitan beaches and coastline. It's a real asset that our city has, and the only other capital cities that rival it are Perth and parts of Sydney, although only the uber wealthy really benefit there.

Or going back a few steps further, the former former government should have never approved the west beach boat ramp. It was clear at the time this is exactly what would happen and they failed to listen.

It shows just how much political decisions can impact in the longer term.

It's also why it's important to make sure the solutions put in place aren't just going to create other problems elsewhere.

Should be as simple as removing them. Let the natural flow of the sand and tides restore the beaches naturally.

This just seems to be a problem that's getting worse as the years go by. Glenelg, West Beach, Semaphore, Henley... How long before we have no metro beaches or just a sliver of sand here and there like Melbourne and Sydney?
Find another solution for people to launch their fishing boats that wont destroy the metro beaches.
Our kids, their kids and so on should also be able to enjoy the metro beaches that we have for generations.

Well rising sea levels pretty much guarantee we won't have beaches by 2060/2070s onwards.

Unfortunately I think we'll destroy them long before any possible sea level rises, that we've been hearing about since the 70's.

I've driven to Yorke Peninsula. There's a limit to how far north the sand can drift, someone could go to Port Wakefield and bring it back.

Has anyone asked the Kaurna people what the beaches were like before there were buildings on the front row of dunes? Perhaps it naturally comes and goes, but now we've anchored the reserve supply so the beach "disappears" instead of moving east a few metres.

Don't need to ask them, you can just go back a short time to before marinas, boat ramps and artificial breakwaters were built along the coast that have disrupted the natural movement of sand and tides. All so some recreational fishers can launch their tinnies a few times a year.

They were going to build a pipeline under the sand to pump said sand along the coastline to where it's needed. What happened to that? How well would that have worked? Was there going to be some sort of system developed that monitors the volume of sand per beach before it kicked in and started pumping sand around?
It's 2023 how the hell is there still not a proper solution beyond carting sand up and down beaches

If they were the complete problem, wouldn't it be temporary until sand piled up on the southern side of these structures, then go back to drifting as usual?

I'm not a hydraulic engineer, so perhaps that's a bit simple, but in general, if sand "naturally" drifts north along the beaches and something is built near the shore that blocks it, there should be a pile up then it continues. I'm also not sure where it's all going as the Wakefield River doesn't have piles of sand in it.

It builds up first at Point Malcolm where Semaphore Park bows out into the gulf. When it gets around that it builds up at the northern end of Largs Bay, where it is stopped by the southern revetment mount which forms the entrance to Outer Harbor. AFAIAA This is where it is collected from to get trucked back to Brighton and Glenelg.
When I did high school geography many many years ago I learned about a phenomenon called long-shore drift, where the natural movement of water via tides and currents cause this. It can be slowed by constructing groynes out of huge sand bags filled with quarry rubble, at regular intervals along the beach. Still, sand will build up on the south side of the groyne and be depleted at the north side.
I dare say before we started interfering with it, the coastline on the east side of Gulf St Vincent would have seen quite a bit of movement.

There is already a system like this between Glenelg and Seacliff. The northern pipeline was part of the Liberal re-electon plan, but cancelled under the Labor government because of "excessive noise" or something like that.

They were going to build a pipeline under the sand to pump said sand along the coastline to where it's needed. What happened to that? How well would that have worked? Was there going to be some sort of system developed that monitors the volume of sand per beach before it kicked in and started pumping sand around?
It's 2023 how the hell is there still not a proper solution beyond carting sand up and down beaches
There is already a system like this between Glenelg and Seacliff. The northern pipeline was part of the Liberal re-electon plan, but cancelled under the Labor government because of "excessive noise" or something like that.
Is that really the reason they gave for canning the project? :lol:

Yes, I'm sure the trucks carting sand up and down the beaches will be as quiet as a mouse.

This project was axed to fund Labor's other election commitments.

How well does it work?
Glenelg seems to have a pretty deep beach, as does Seacliff but in between it seems to thin out.

You can read more about sand pumping here: https://www.environment.sa.gov.au/topic ... nd-pumping

"Sand pumping continues to perform well from Glenelg to Kingston Park."

They can discharge sand at various locations between Glenelg and Seacliff. It is not a year round process, they need to bring infrastructure the to beach to do it. It is not done in summer.

There is also a pipeline at West Beach from the outlet to West Beach dunes. It is not in use however - "Currently the Torrens Outlet to the West Beach dunes pipeline (Cell 3) is not being used. The 2018 DHI West Beach report determined that large volumes of sand are needed to stabilise the foreshore. The pipeline will need to be part of the solution in the future." Sand pumping continues to perform well from Glenelg to Kingston Park.
