Hard engineering involves building artificial structures to control natural coastal processes - think concrete walls and massive boulders protecting our cliffs. These methods directly fight against the power of the sea.
Sea walls are concrete barriers placed at the base of cliffs to prevent erosion. They're curved to reflect wave energy back into the sea, which makes them brilliant at protecting cliff bases. You'll often find promenades built on top for people to walk along. However, powerful waves can damage them over time, and they're seriously expensive at £2000 per metre.
Rock armour uses large boulders placed at the foot of cliffs to break waves and absorb their energy. It's cheaper than sea walls, easier to maintain, and can even be used for fishing. The downside? These imported rocks look completely out of place and cost a fortune to transport.
Gabions are rocks held in mesh cages and placed in vulnerable areas. At just £100 per metre, they're the budget option that still absorbs wave energy effectively. Unfortunately, they're not particularly strong and look quite unnatural.
Quick Tip Remember that groyne structures are built at right angles into the sea to trap sediment and build beaches, but this can increase erosion further down the coast.
Soft engineering works with nature rather than against it - no artificial structures needed, just sustainable and natural approaches that let coastal processes happen whilst managing their impact.
Beach nourishment involves pumping sand onto beaches to build them up artificially. This creates larger beaches that attract more tourists and blend in naturally with the coastline. The major drawback is that sand constantly needs replacing, and it has to be brought from somewhere else, which affects other areas.
Beach reprofiling redistributes sediment from the lower part of the beach to the upper sections. It's cheap, simple, and reduces wave energy effectively. However, it only works when wave energy is relatively low and needs to be repeated constantly to maintain effectiveness.
Dune nourishment plants marram grass on sand dunes to help trap sand naturally. This method is incredibly cheap and maintains a natural-looking coastline that doesn't disrupt the environment. The problem is that storm waves can easily damage these defences, and areas often need to be fenced off from the public.
Remember Soft engineering strategies are generally more sustainable and environmentally friendly, but they require ongoing maintenance and may not be suitable for areas with high wave energy.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!

Coastal management is all about protecting our coastlines from erosion and flooding using different engineering strategies. There are two main approaches: hard engineering (building artificial structures) and soft engineering (working with natural processes).
