Stockton Sand Nourishment Begins

Swellnet Dispatch

In December 2019, following five years of slow erosion at Stockton Beach, Newcastle Council took matters into their own hands. Stumping up $350,000, the council trucked in 5,500 tonnes of sand and dumped it just north of Stockton Beach Holiday Park.

At the time, Lord Mayor Nuatali Nelmes said it was "only a short-term response" and she wasn't wrong. "It lasted about a month. It's all moved offshore now," Stockton local Simon Jones told Swellnet back in February 2020. "The beach down there is the same as it was."

Shortly afterwards, the Stockton Beach Taskforce was established by the NSW government to find a long term solution to the suburb's erosion. You see, prior to 2020, the Stockton beachfront had been slowly yet inexorably retreating, largely in response to dredging of the entrance to the Hunter River. There's no doubt the breakwaters to the Hunter River adversely affected Stockton, however they're over a century old and the coastline immediately north had reached a new equilibrium. More recent changes, such as the channel dredging, was upsetting that balance and the results were starting to bite.

What Simon Jones and other Stockton locals weren't to know, however, was that things would quickly get worse. Shortly after the last round of sand nourishment the East Coast would suffer from a protracted La Nina, replete with weeks and months of sand-shifting easterly swells, and the situation would become dire. It was no longer a case of losing the beach; loss of property became a very real threat.

For three years the cogs of bureaucracy slowly turned until late last year the Stockton Beach Taskforce began bearing fruit. The NSW government annouced a $6.2 million rescue package for Stockton, with the Federal government chipping in $4.7 million towards the project, with City of Newcastle $1.5 million. For their part, the State government would oversee the approvals process, locate sand for nourishment, and co-ordinate its delivery.

"It's only right that the NSW Government take on this critical role given it is their infrastructure, namely the breakwater and deepwater navigation channel of the Port of Newcastle, that has been proven as the primary cause of ongoing erosion," said Lord Mayor Nuatali Nelmes pointedly.

Starting last week, Phase 1 of the project began with the Trud R, a curiously named suction hopper dredge, extending its appendage to the sea floor and 'rainbowing' its load back onto the beach. The plan is for 100,000 cubic metres of sand to be "strategically placed" at the southern end of Stockton during this phase.

"They’ve been dumping in the same 100 metre stretch since lunchtime Saturday," reported Simon Jones. "I think they do about six loads a day, with something like 1000m3 per load."

"I had a look this afternoon at low tide and you can see a bit of a spit starting to form."

Previously, hard solutions such as an artificial headland were proposed but ongoing sand nourishment appears the preferred course of action, pending continued support from the NSW government.

“The long-term solution is to secure the 2.4 million cubic metres of sand needed for initial mass nourishment," said Michelle Bisson from the City of Newcastle, "and annual sand top ups in line with community wishes and the plan endorsed by the NSW Government."

After a half-decade without any appreciable sandbanks, not to mention the threat of property loss, campaigning surfers such as Simon Jones are watching it all unfold with interest and not a little bit of excitement. "We’re hoping [the NSW government] takes ownership of the project to place all 2.4 million cubic metres."

The Trud R in action. "They’re often landing the sand onto the dry beach," observed Simon Jones. "Testament to the lack of offshore sandbars." (Ron Boyd)

Recently, Swellnet ran an article highlighting the rapid return of beach widths following the quietest winter in recent history, though clearly not everywhere shared the bounty. Six months of small swell and this stretch of Stockton has only ten or so metres of sand (Simon Jones)

C'mon, it's better than an attempt to 'catch' the setting sun (Simon Jones)

good on the council pointing the finger at the state governments infrastructure as causing the problem to the roads and houses they allowed to be built on the dune.
I find it interesting that Nobby's beach seems to be excluded from the source of blame for the issues at Stockton and is rarely mentioned in the studies on this sand nourishment. happy to blame the Port / break wall / shipping channel for disrupting sediment transport, but ignoring that Nobbys is largely a manmade beach.

I used to live by nearly 20 years ago and those photos make it look to me like the Stocko is looking better than it ever has for width in beach. It used to be a vertical sand wall from my memory. Hopefully they can keep up the funding for this, I'm no engineer but it seems far better than building the f-off concrete wall to protect properties as we have seen of more recent examples in northern suburbs of sydney so hopefully it works.. I agree, excellent photo at the end :D

Yep, apparently the coastal management team there is presenting a full long-term strategy sometime in 2024. Don't know what other strategies that might include though.

Back in the late 90’s various options including an artificial reef and scuttling a ship to protect that coastline were considered but they never gained traction because of cost and uncertainty. Everyone knows that sand replenishment is at best temporary and a waste of money, but it is an acceptable band-aid solution that avoids hard decisions.

The northward flow of sand into south Stockton has been effectively completely cut off by the Hunter River breakwalls and deep water shipping channel. Studies have suggested that no matter what the solution, there will need to be ongoing nourishment activity to stop the ocean breaking through the peninsula to the river.
That being said, there have been various options put forward to help slow the recession and loss of sand. The favoured option was the construction of an artificial headland. But this is expensive and comes with the problem of only pushing the erosion further north.
The endgame is to do a large scale nourishment campaign (2.4Mm3 sourced offshore), which should restore the beach to a natural state, and then after 10 years add 120,000m3 every year to offset what, on average, is lost annually.
It’s essentially a smaller scale version of the Tweed Sand Bypass, but without a fixed pumping system. The issue is essentially the same as what they were facing up there.

Restore the beach to its natural state?
That's a very confusing statement.
They extended the south break wall in the early 2000' S
Without considering the effects it would have.
You can see the extension on Google maps. Stocko south end has always had erosion. I remember on big swells waves at the little beach to the left.
The hunter river is just too strong and large to control .
At some point in time they may even loose part of stocko.

This seems to be very band aidy.

I suppose natural state is a relative term. What I mean is that the localized coastal processes would work in the way they should of there was no breakwalls.

At the moment there is, on average, 120,000m3 of sand lost from the south end of the beach every year. This happens because the sand north of the breakwall continues to move north, while the breakwalls block almost all sand flow from the south (see the evolution of Nobbys Beach).

By intervening and adding 120,000m3 via dredging, it negates the effect of the breakwalls and allows the normal coastal processes to occur.

Most beaches have a foredune and offshore bar that adapts during erosion or accretion events. This offers protection in a storm. Stockton has lost both of these features, and has a solid seawall along much of the beach. That means that during a big swell there is no bank offshore to dissipate wave energy, and no foredune to donate sand to create an offshore bar. So, the more the beach erodes, the deeper the offshore zone gets, and the more prone the beach is to erosion. These are not the beach in a natural state, and that’s what needs to be addressed. The most effective way to do that is to restore a natural sand flow. It worked on the Gold Coast with the Tweed River Sand Bypass.

I think artificial beach nourishment will become necessary for a lot of beaches in the future. Any beach with a seawall will start seeing the sand disappearing as sea levels rise. If we want to keep our beaches, we either need to rip up seawalls, and knock down houses to let the shoreline adapt, or we need to look at options to artificially maintain the beaches.

yep probably an offshore reef or structures to break the swell up.....i noticed on my beach today with the solid south swell and the large high tides that it is changing from fairly flat to a 30 deg angle now .......hopefully for the better cause it was crap with pretty much closeouts before.

Found the 'Extended Stockton Coastal Management Program' site and it says that aside from sand nourishment, that an artificial headland, artificial reef and sand back passing options are still on the table.

I’m not sure if Stockton entirely fits the wealthy waterfront homeowner tag. It’s a long time since I’ve been there and locals please correct me, but Stockton was very much a working class suburb. I’m sure richer folk have moved in these days, but I don’t think the beach is lined with expensive modernist glass and chrome barns. There’s a road between the beach and the houses with the ocean view and, looking on street view, on the shortish strip of those houses they still look relatively modest.

All house sales on the waterfront at Stockton in the last 12 months were between $2.5m to $3.5m. Perhaps not at the same level of wealth as Collaroy or Wamberal, but still very wealthy people. No issue with them having coin, good on them, but just saying that wealthy people who buy next to sand are not high on my sympathy list.

Yep Stockton is a time-warp, that's why they film 80s shows there (Frayed - I accidentally walked on set going to my gp).
We were able to rent two "beach front" (Mitchell st) properties from 2012-15 as students... split 4-5 ways. Two gross mansions were built next door during that time but 95% of Stockton is very modest. Well back then at least.
A very frustrating beach for learners, and I saw the beach destroyed by erosion multiple times.

if you want to do a sand study Have a look at Coffs Harbour Jetty boat ramp fiasco. Man made shit doesn't work with the ebb and flow of sand . Build it and the sand will fill it ! We could have a super bank here by pumping sand! But obviousley the engineers in the office don't surf! But like to waste money by drawing lines and studies done in fantasy world. The Tweed model works generates revenue keeps the masses entertained and off the crack ( maybe ) . Permanent dredges pump sand if you block the flow . Yes we are all suffering from beach closeouts !

The funny thing with snapper was they actually buried many great waves and pumped too much sand , proceeding to fuck all the nooks and crannies to the north.
More over alot of locals were pissed at the creation of the super bank even buggs.
You have to be careful as to what you wish for.
Snapper turned on green mount turned more novel Kirra got buried.
That's history 20 + years of makes and mistakes.

Apparently in the 60s, in a big south swell, the offshore bar was still shallow enough that you could surf from the end of the breakwall all the way in the the surf club. That’s a 1km ride. There are maps from the 1800s that show it being 2ft deep all the way out to about 1km offshore. They called it the oyster bank. If you compare the angle of the breakwall to the angle of the Superbank, they’re almost the same.
I’m not saying that it would have been as consistent or, as good as the superbank, but I guess we’ll never know.

Ain't no south-flowing longshore drift between the Hunter and Fraser, LD.

If it happens, it's short-term, driven by prevailing swell, the drift stopping when the swell does. All aggregate flow is north in that zone.

What's the issue if the sand drifts south towards the breakwall?

As evidenced by the largest amount of sand at the very south end of the beach, there could probably be a slight eddy current heading that way during large south swells; or it may be that it rarely gets bigger waves and associated currents in the corner.

The great photos in todays Newcastle surf report show the futility of these efforts...
https://www.swellnet.com/reports/australia/new-south-wales/newcastle

The Aboriginal people, in this area, the Worimi, are the first people of this land. The Worimi people call the area Burrabihngarn. This name is acknowledged by the NSW Geographic Names Board in the official dual-naming of Pirate Point / Burrabihngarn. During the year clan groups moved around their traditional land and in the summer months the mullet run drew them to the coast. This time was used to maintain kinship connections.

What if they blast or tunnel under the whole hunter region, remove all the coal, the extensive tunnel network & pits fill with water and when the earth slips and quake hits, merge the mining company O/S, retrench the workers and call it ...Billion-ton.

Things look surprisingly unchanged, except that there are real dunes north of Pines (adjacent to the north oval). There's some rehabilitation along the block immediately north of pines, but otherwise it's grass and seawall until the end of Mitchell st. It did its job in June 2016 though. There's also a crude seawall between the surfclub and pines which is made of demolished buildings, no idea of age and it reappeared after 2016 from memory.

Can we get a temporary surf cam to monitor Stocktons revival and inevitable destruction? For science
