More serious erosion occurred from the 1970s to 1980s. The only alternative left to save the beach, and the one with the best chance of success is sand nourishment. Adelaide beaches – eroding & protected by seawalls & nourishment, Photo by Andrew Short. The coastal management plan will use 80,000 trucks over six years and will cost more than $52m. A group in Australia claimed that sand from Stockton Beach in Newcastle, Australia, was shipped to Hawaii many years ago. ‘‘Exceptionally large swells  and tides over the past week has eroded the beach creating dangerous drop-offs, flooding and making parts of the beach impassable to all vehicles,’’ National Parks and Wildlife Hunter coast manager Andrew Bond said. Pollution degrades and destroys unique beach habitat used by animals and plants. On Monday Newcastle’s lord mayor, Nuatali Nelmes, called on the state government to declare a natural disaster at the beach, saying property and community safety was “under direct threat”. At Stockton Beach, north of Newcastle, ... What the problem is, the coast is eroding, it happens all over the world. Sand builds up on the updrift side of a groyne, but erosion occurs on the downdrift side. Net northward movement is the case for all of the NSW coast. They work by making waves break offshore, reducing the energy on the beach behind them. In the next 25 to 30 years the prediction is Hawaii shores could lose 100 feet of beach. The BBCS conducted beach profile studies and concluded that from 1989 to 1993 the amount of eroding shoreline in Florida increased from 332 to 356 miles. Deposits are made if we get longer periods of fine weather with small waves and lower tides. Waves are powerful forces that continually pound on the shoreline. The smaller Stockton breakwater was built in 1886, and the longer 1136 m Stockton breakwater completed in 1912. “Devastating” erosion at Newcastle’s Stockton beach has put the future of surfing and surf live saving in jeopardy, as anxious residents await further damaging swells at the end of the week. T he tourists are leaving and only coming back to take photos of houses that are falling in to the sea, and brick and parts of houses that are scattered along the lovely beach that it has to offer. Sand is normally transported seaward in rip currents and erosion is made worse if several large storms like east coast lows follow each other during the winter. Eroding beaches also mean less habitat for species of animals and plants that are dependent upon the dunes and beaches. Another historical indication of the sand once present on the beach is the old mine workings near the Mission Australia Early Learning Centre. Early maps of Stockton and the Hunter River entrance from 1866 and 1887 show a typical NSW tidal inlet with 6m deep, 90m wide channels, and extensive sand bars on the northern side. Beach Erosion. This appears to be the default current solution adopted by Newcastle Council and is presented as part of Newcastle Councils 2014 Management Plan. This plan unfortunately contains no short to medium term solution for the Stockton erosion problem, recommending yet more studies, and decisions postponed until later completion of a second Coastal Management Plan. It also has Lexie's on the beach for coffee and meals. Good nearshore surfing banks were common during that period. Previous studies at Stockton have shown that the northward movement of sand is around 30,000 m3 per year, starting around the seawall and increasing to the north. This can be thought of as a budget, and similar to a bank account. Stockton has 3 hotels, 2 licensed clubs, 2 hamburger/fish & chip shops, 2 Chinese restaurants and a pizza shop.

It has all the bad features of artificial structures like breakwaters, offshore breakwaters and groynes. This northward movement is the main reason for Stocktons beach erosion. A lot of onshore/offshore movement is seasonal or cyclical and is driven by climate. While the erosion is cyclic, the cycles are superimposed on a downward linear trend with little sand volume now available for natural rebuilding. The beach and the road are eroding away so during times of high tides there is no […] See details . Other hard structure solutions that have been proposed for Stockton include groynes, offshore breakwaters and artificial reefs. It will need to be replenished occasionally, just as the harbour requires maintenance dredging. Beach erosion occurs if we get more big storm events than periods of fine weather, and if more sand moves north than is replaced from the south. During the last half century, innumerable studies of the Stockton Beach erosion problem have been undertaken. Sand then moves onto the beach and accumulates, typically in summer with more northeast winds and waves. Consequently, the beach erosion is threatening the housing thus NCC focuses its management on ensuring the beach continues its function for storm protection. Elsewhere, mainland beaches can be quite low, such as those found in northern New Jersey and Delaware and along parts of the Gulf coastal plain. Adelaide, SA. The northern source is sand that has already been transported from south Stockton, while the offshore lobe and harbour entrance has sand that should have been transported to Stockton if the breakwaters did not prevent it. This occurs when waves approach the beach at an angle and transport the sand in the same direction that the wave is travelling. The most obvious construction has been the breakwaters. This problem has been an ongoing and unresolved issue for more than 60 years. However, human activities can also strongly influence the propensity of landforms to erode. Stockton has lobbied for better sea defences in the area for many years, eventually securing £4million for improvements to the town’s Victorian-era sea defences. A steady progression of dredging and construction occurred since 1866, with dramatic results for Stockton Beach and the offshore bars. “The council is doing a fantastic job, but 5,500 tonnes of sand and more was lost to the storm,” she said. Seaward movement results from big waves such as in the Sygna or Pasha Bulker storms combined with high tides. Sand dune stabilization is a Coastal management practice designed to prevent erosion of sand dunes. It is not a regional NSW beach erosion or climate change issue. At Stockton this would move the problem north to Griffith Avenue and up to Corroba Oval. We have seen this already in the addition of the short seawall from Lexies Café to the surf club, and the recent extension at the northern end off Stone Street.

The problem has become so bad - the local childcare centre has been forced to close. Erosion Risks . The first is onshore/offshore transport, when sand either erodes seaward off the beach to deeper water, or deposits from deeper water back onto the beach. Seawalls are only a temporary fix, they are not a long term solution. The beach that lost some 20,000 cubic metres of sand to large swells last year has been battered again. The same thing is happening at Stockton where the Newcastle breakwaters stop the flow of sand from Nobbys Beach around to Stockton. The current artificial channel is now more than twice as deep as it was in the 19th century, and at 150 m, is much wider too. Understanding and combating beach erosion can be a complex issue. The damming of most waterways in the US has thus prevented a major supply of sand from getting to our beaches. This occurs because sand behind the seawall cannot be accessed during an erosion event and has to be sourced from the beach adjacent to the seawall. Because the waves break offshore there are none near the beach, so fishermen and surfers would not benefit from this option. Happisburgh used to be a great family place to go in the summer, but as it is wearing in to the sea. Offshore sand nourishment is currently being successfully used to prevent erosion on Queenslands Gold Coast. This option works by adding more sand to reduce the wave energy by friction before it reaches the beach. The NCC is currently preparing a new Coastal Zone Management Plan, due for consideration by Council in July 2018. Bad example: The harbour in Ventura, California, resembles Newcastle. The ongoing beach erosion since the 1980s has seen the construction of the seawall from Pembroke to Stone Street in 1989, and the sandbag wall at the surf club in 1996. The seawall requires ongoing maintenance to prevent it being damaged (estimate for 2018-19 work is around $3.5m), and the lifespan of the current seawall will eventually end. Sand dunes are common features of shoreline and desert environments. “It’s OK for the older generation who know how to swim and have established themselves in life, but with the kids we’re losing an entire generation,” Forsyth said. These bars contained large volumes of sand, deposited in the ocean by waves and the falling tide as it flowed out the entrance channel. Lots of summer northeast waves can also send sand southward temporarily, but this is normally only a short term effect.

One option to solve the Stockton beach erosion problem is to extend the seawalls until they eventually stretch from the breakwater to Corroba Oval. The headland option located north near Fort Wallace was preferred as it would place a barrier to sand moving north and retain the new sand for a longer period. Seawalls are much less visually attractive than the dunes and beach they replace. Of the three islands, Maui beaches experienced the highest rates and greatest extent of beach erosion with 85% of beaches eroding. Older Stockton residents remember the worst erosion of the late 1940s to early 1950s when parts of Dalby Oval were lost. The major sediment sources for the beaches of southern California are eroding headlands and adjacent beaches and, to some degree, sediment from local rivers in flood. Waves Effect on Erosion. The 410,000m3 required could be scraped from Stockton Beach north from the Hunter Water lands, or dredged offshore from the sand lobe off Nobbys Beach or the entrance to Newcastle Harbour. The general trend in coastal management is to move away from hard structures and armouring of the shoreline as a solution, and at least four US states have banned their use. On the Stockton side, we have learned that there has been an astonishing loss of over 10 million cubic metres of sand since 1816 at an average rate of 41,000 cubic metres per year. When a storm comes, they stop the surge from pushing too far inland. The 50m-wide North Stockton fourth sewage pond situated next to the ocean was lost after 1974. Once the beach is lost in front of a seawall, it becomes dangerous to access what is left of the beach. Continuing delay in fixing the problem is unacceptable. Das erwartet Sie In World War II it was fortified against a possible attack by Imperial Japanese forces. As a result, there is not much sand on the south coast around Batemans Bay, but lots in the north in places like Fraser Island. This depth was increased to 8.4 m by 1950; 11.6 m by 1964; 15.2 m by 1983, and now 18 m deep. Miramar Beach parallels Mirada Road in the Miramar neighborhood in Half Moon Bay.
