Gabions is a method of Hard Engineering on coasts
One engineering strategy that has been used to protect coastlines from erosion is the construction of seawalls. Seawalls are vertical structures typically made of concrete or rock that are built along the shoreline to absorb and deflect the energy of incoming waves, reducing their erosive force on the coast. Seawalls can help prevent coastal flooding and erosion by providing a barrier between the sea and the land. However, it's important to consider the potential impacts of seawalls on coastal ecosystems and natural sediment transport processes when implementing this strategy.
Offshore wind turbines are manufactured in coastal factories or shipyards designed to handle large structures. The components, including blades, towers, and nacelles, are built separately and then transported by ships to designated offshore wind farms. These locations are carefully selected based on wind speed, water depth, and accessibility to the power grid. Once at sea, the turbines are assembled using specialized cranes and vessels, ensuring they are securely anchored to the seabed or floating structures, depending on the depth of the water.
Two examples of Incan technology are: 1) the two roads they built which ran the length of the country. The Royal Road went through the highlands for a distance of 3,250 miles, while the Coastal Road followed the seacoast for 2,520 miles. 2) The site of Machu Picchu was constructed by Inca engineers. The Inca constructed stone temples without using mortars yet the stones fit together so well that one could not fit a knife through the stonework.
The air moves in the exact same manner regardless of the time of day. However, air near the ground in areas where the ground level consists of vastly different materials, typical airflow during night may differ from the typical daytime situation. For example, in a coastal region, land (rocks, sand) might meet the sea. During the day, the rocks heat up quicker than the large body of water, so the air starts to rise above the land, and the local air flow goes towards the coast. However, during the night, the shore cools but the sea maintains its temperature, causing the wind direction to change to a seabound breeze during the night. These conditions can be observed in nature, however, local climate, weather conditions, currents and conditions on the shore as well as in the water will affect this phenomenon.

Gabions are commonly found in construction projects such as retaining walls, erosion control systems, coastal protection structures, and landscaping features like garden walls and benches. They are also used in military applications like bunkers and barriers.

Coastal management is needed in Britain to mitigate coastal erosion, protect coastal habitats, and reduce the risk of flooding to coastal communities. This is important due to rising sea levels, increased storm intensity as a result of climate change, and the high population density along the coast. Sustainable coastal management practices help to maintain the ecological balance of coastal areas and ensure the long-term resilience of coastal communities.

Hard Management: Hard management is the more traditional response to erosion and involves the construction of structures which stop wave energy reaching the shore, or absorb and reflect the energy. These have often caused problems themselves, such as increasing erosion elsewhere, and soft construction techniques have become more popular because of this. Soft management: These techniques involve promoting natural systems such as beaches and salt marshes which protect the coast, and are usually cheaper to construct and maintain than hard management techniques, and may be self-sustaining.

to prevent future flooding
the advantages are that it helps to protect the coast line by stopping the waves pounding at the cliffs. it does this by breaking the power of the waves when it hits the little rocks inside the cage. gabions are quite natural as rubble or pebbles can be used. gabions are also quite cheap and may be prefered to other coastal defenses such as sea walls. the disadvantages are that they may be considered unsightly by some people, they may take up quite a lot of space up on the beach as lots of gabions are needed to provide plenty of protection ( this makes the beach less desirable to people as the beach may seem more crowded) if the rocks inside the cage become worn down the whole cage will need taking out and replacing. if the gabions are stacked up in a wall and a lower one needs replacing this will mean taking out all the ones above it aswell before replacing it and rebuilding the wall. this would take lots of time and money! A timber crib retaining system offers an excellent alternative solution being generally faster and more simple to construct without the need of skilled or experienced labour. Timber crib can be used in both domestic and commercial applications and are considered by many as aesthetically superior to gabion baskets in addition to being environmentally friendly and sustainable.
