Marsh May Help Fight Coastal Erosion

ENGLAND -- Many of the defences of the coastal seas have been erected since the great flood in 1953. The same flood killed more than 300 people in Essex, Norfolk, Lincolnshire and Suffolk. The disintegrating defences need to be replaced to keep the worse from happening. However, the continuous increase in sea levels not to mention the outrage of the violent storms, rebuilding these defenses have become higher and more expensive as an option. Since tourism proves to be one of the most economical way for these areas to earn, another way has to be found. This new way may just provide the birds and other marine aquaculture to benefit in it.

The fish nurseries alongside the bird sanctuaries all represent valuable assets not only to the environment but to the economy as well. The presence of these creatures strikes a beautiful balance in the ecology of the natural space. More than that, it helps keep the tourists coming and that brings about economic benefits to the community.

Research has been conducted as to how the coasts of East Anglia could fight this problem on coastal erosion and the result show the the salt marsh might be the best way to fight it. The salt march may only be 40m wide but it can help reduce the height of the waves by as much as 20%. If the marsh is about 80m wide, it can bring the height to the waves down to as low as zero.

The researchers from Cambridge along with other experts from various universities in the region have seeked the help of national conservation groups like the National Trust. They own lots off the coast and they have every intent to expand on marshes. From the how the topographical map, the place might require a seawall to be built in the future. The study shows what experts need to keep the coastal areas safe from total destruction.

The cliffs were demolished by the storm waves. In fact, the waves were so  strong that they were able to bring solid concrete walls down. The overall plan is to retreat inland slightly and try to develop softer defences in front of coastal settlements and valuable farmlands. This is to prevent much larger areas in the coastal land destroyed. The least that people want to see if or the East of Anglia to be totally swallowed by the sea.

Though the research aims are providing more possible solutions to this growing problem brought about by climate change, it needs to take the studies further to find for helpful information.
