Any chance of a dedicated ErosionCam, Swellnet? However, the work then continued skyward with a seven metre vertical concrete wall on top of the foundations. Seawall construction isnt mentioned. It would be fantastic to see an interview with someone from Many Hydrolics as they did all the Scientific modeling and have been very open in sharing their data. Step 5: Construct the Seawall. (9News) But the structure has divided locals, with many describing it as an eyesore, and there are concerns it may wipe out the beach entirely. Not sure how they would fix them to the sand though.

Comparing the swell to those of last year it wasn't of any major significance but it shows the futile efforts trying to protect property with a hard structure. Just wondering if the stairs built into the wall are private property? There are many software suits now that can handle very complex near-shore modeling, including sediment transport from wave and current action. You may not realise that there have been large volumes .

However, the bean counters and quantity surveyors were extremely difficult for obvious reasons. If they are falling into the ocean or they require extensive works or continual maintenance, then what is the market value? Here's the full video with audio.

Its no wonder the climate brigade aren't on board telling us all there garbage but erosion been around a tad longer than the 80s. "When a hard structure is introduced to the equation we see an increase in reflective energy and turbulence, slowing the accretion of sand while also accelerating erosion in storm conditions."

Any chance of a dedicated ErosionCam, Swellnet? However, the work then continued skyward with a seven metre vertical concrete wall on top of the foundations. Seawall construction isnt mentioned. It would be fantastic to see an interview with someone from Many Hydrolics as they did all the Scientific modeling and have been very open in sharing their data. Step 5: Construct the Seawall.

Its no wonder the climate brigade aren't on board telling us all there garbage but erosion been around a tad longer than the 80s. "When a hard structure is introduced to the equation we see an increase in reflective energy and turbulence, slowing the accretion of sand while also accelerating erosion in storm conditions."
