Alas this would have meant some loss / damage to private property. Why would you bother acquiring the affected properties "at any cost", when they're likely to be washed into the sea? Some relevant links from when I had a dig around before. Compare their prediction of how it would look with the reality shown above.. https://www.eventbrite.com.au/e/climate-change-and-coastal-erosion-the-g GOR coastal erosion webinar link for today at 3pm for those interested. It's an interesting point whether you just blame the owners for buying a house in such a risky area and hoping taxpayers will bail them out, versus the fact that the council must have approved people building houses there in the first place (although possibly a very long time ago), "Professor Short said the council bought properties along the beachfront and turned them into parklands in the 1970s and attempted to put a moratorium on redevelopment in the 1980s, but lost its case in court.". that concrete is a lovely blank canvas for some choice words.

The area has been slowly receding due to storm damage - theres evidence of erosion dating back to the 1920s - while at the same timebeing intensely researched by coastal geographers. But unlike a rock revetment at Stockton, which gradually collapses into the beach, Collaroy's sheer concrete wall relies on deep foundations to stabilise it. Scientists need to be able to communicate the results of simulations/tests in a way everyone gets, not just a bunch of numbers. It never stood a chance.

It would be a good idea to put in a surf cam in that pans up and down the wall to document any changes to the beach, sand movements, erosion problems etc. No more excuses for your terrible workmanship anymore. Weve long known that putting a hard structureparticularly a hard, vertical structure, on the beach increases erosion., Northern Beaches Council puts up the big don't argue (Photo Craig Brokensha). Like I said at the start, IF he is an "expert coastal engineer" then we are in a much deeper hole than I imagined. Willi, how would easterlies impact the Great Ocean Road coast? Thats awesome. That is why this option was selected for Palm Beach Qld, and I think should be considered for all the other coastal erosion hotspots along the NSW coast as well. check out the beach erosion in Apollo bay as well Click on "Documents" for the interesting stuff. Staged retreats seem the best option, but also some councils are genuinely desperate to embrace the most apocalyptic climate change forecasts. "We haven't had a flood here for 20 years you say. The 18-year-old scored a near-perfect 9.50 in the Final, held at Seaside Reef in Encinitas, California. Its like stepping forty years back in time.

Probably not council's fault then, happy to blame the owners! They may have a wall, but there will be no beach in front of it. From their perspective building the wall before further erosion took place and moved closer to the road was another advantage as was disregarding the impact on the beach for a potentially more permanent solution. I imagine the ocean will eventually claw away under and around and over the structure. Premium ad-free surfcams, dawn surf reports, and more had been lodged 18 months earlier in July 2018, http://www.irjes.com/Papers/vol6-issue10/F61012431.pdf.

These contracts to the construction companies are worth hundreds of millions of dollars. Absolutely spot on, Craig. Contrast man-made against a natural barrier like mangroves (apologies for the sound, not my video), Trees work well for preventing erosion ONLY when the wave power is very minimal. Offshore reefs would be expensive , but we are already spending 100's of millions on bad solutions that actually cause more problems than they solve so money cannot be used as an excuse.
