Gold Coast, Queensland, AustraliaGlobal warming causes ice caps to melt, and melt sooner. This phenomenon, in turn, raises the sea level, causing beaches to shrink and coastlines to erode. The threat of rising water and coastal erosion is real. While you may not feel the full effect, it is happening, and environmentalists are taking steps to protect the coast.

Repercussions of Coastal Erosion

Engineering professionals from have conducted studies to understand the hydrodynamics involved in coastal erosion. They found that the phenomenon has different effects on coastlines throughout the country. The impact on undeveloped areas, it appears, would not be as big a problem as the result of densely populated areas like coastal cities. The serious repercussions to the latter include:

  • Flooding – With coastal erosion, flooding may become more frequent and dangerous. There are less blockage and water can quickly fill up the streets and cause flood damage.
  • Loss of Land – The coastal land and beach will continually be pushed back by erosion. When this happens, water can weaken the developed areas and make them unusable.
  • Economic Loss – From an economic standpoint, the absence of beaches will lessen the tourists visiting coastal cities for a swim and sunbathing.

What Can You Do to Fix It?

Geography AS Notes suggests that many projects have been completed or are currently underway that can stall coastal erosion. There are two types of techniques experts use, depending on the location of the coastline and the strength of the waves.

The first is called hard engineering technique. It uses solid materials and non-living things to keep waves from crashing to the shore. It includes seawalls, breakwaters, and tidal barriers.

The second technique is the soft engineering technique, which involves the land within and surrounding the coast. The methods include adding sand and shingle to the shore or creating marshlands to break up the waves and reduce their speed.

The environmental protection industry continues to find ways to protect the coast from unnecessary erosion. With new civil engineers entering the industry every year, more innovative ideas for preserving the beach are added.
