Adding How mangrove forests protect the coasts from wave erosion to the discussion https://www.linkedin.com/posts/pareekhjain_eiirinteresting-engineering-activity-6867694267779948544-2EZb

Another solution to limit coastal erosion and generate electricity is a floating dyke from a French start-up called HACE (hydro air concept energy) : it is floating containers using wave to compress trapped air and drive air turbines. This wave energy conversion principle is called OWC (Oscillating Water Column). HACE wave energy converter produces also the world cheapest marine energy (< 30$/MWh).

Thats really interesting. It makes me wonder why Eastbourne employ lorries and diggers to reposition littoral drift annually, when a permnent solution could be sought. Or am i missing something?

Mart Reiling haha weet je nog ons profielwerkstuk?

So the rocks on Marine Drive actually have a purpose too

This is a great experiment I enjoyed watching BUT as you know the major problem to solve shoreline erosion is money. I own 3 oceanfront resorts in the Gaspe Peninsula and damages from the strength of the St-Lawrence Gulf have cost us in the hundreds of thousands over the years plus losing precious land. Without the help of governments I doubt this can be realistically done. That being said I am a GC as well and would be open to join forces and invest as well, with anyone willing to do the same, in order to challenge other cost conscious ideas... I've had a few over the years...and who knows maybe sell our invention all over the world one day!

In short: highly problematic, lacks integrity and scientific robustness. Please don't fall for the idea that this overly simplistic model can represent a discussion of coastal protection solutions for a "beach environment" with integrity. Calling a smooth, impermeable plastic slope a "dune" model demonstrates a complete lack of understanding of sand beach dynamics. This is early 20th century framing of how beach issues work at its worst. Robust 21st century coastal engineering recognizes how beaches function and provides a range of potential solutions to storm and sea level rise challenges, outlining their pros and cons, and considering the benefits of each, as well as where possible considering working with nature. Thank you mangrove video sharing person. The above clip should be a call to thought leaders in coastal engineering to post robust, credible alternative clips. Videos like the one above do your profession, and communities facing real world coastal challenges, a disservice.

Nice model – a wind simulation combined would be nice ;-) In Gambia, I saw how such walls just got washed away when water pressure from the land side of the walls rose during heavy rainfalls – with extreme weather events due to climate warming, such effects will follow in places not affected before. More concentrated and thus stronger water flows in the sandy ground were as well in play in Gambia as more and more buildings have been built, trees cut down, vegetation cover replaced by lawns and surfaces sealed for streets, parkings etc. – a perfect recipe for erosion, especially with sandy or carstic land.

What about no wall with natural berm with vegetation and not have houses directly on the beach front!!!....just thinking of Collaroy.

I think our school should have a topic to teach comonscience to understand nature to deal with problem.
