15 Effects of Ocean Currents on Adjacent Coastal Areas

by Ayu Mesdya

As humans, we must keep all the wealth on earth so as they are not to quickly become extinct. However, there are some natural and human factors that can destroy the environment. Below here the following 15 effects of ocean currents on adjacent coastal areas.

1. The coastal erosion

The activity of ocean waves and ocean currents can lead to the coastal erosion where this activity is a continuous erosion of coastal land through the waves and ocean currents. This natural phenomenon can also result in the descent of land so that the land appears lower than the oceans. Of course, this phenomenon can increase the risk of the overflowing sea water to the mainland (flood).

2. The shrinking of coastal region

The first real impact on coastal erosion is the shrinking of the coastal region. The activity of the sea waves that hit the coastal area can continuously take off about 5-10 meters from the beach.

In addition, the continuous abrasion that hit the coast will also inundate areas that were once a residential population or tourism sector. This is very detrimental and endangers the sustainability of the population and business in the tourism sector. Read more about Main Elements in Ocean Water

3. The damage of Mangrove Forest

The damage of mangrove forests also has the potential to increase the risk of coastal erosion. If mangrove forests have been damaged, the coastal abrasion can no longer be mitigated. The damage of mangrove forests usually occurs during the hurricane season.

The destruction of mangrove forest can also occur due to the massive sand mining in high intensity. If the balance of the ecosystem has been damaged, and the sea has lost its sand supply. Both of these need to be addressed more intensively to reduce the risk of coastal erosion.

4. No more habitat for fishes

It is not only humans who do not have the shelter, the erosion of coastal areas can also cause fish on the coast to lose their habitat.

if the coral reefs mined to be used as souvenirs. The fishes are along the shoreline will lose their habitat, because of the predatory threats, the unsuitable of the sea water temperatures and the big of sea waves. The worst thing is, these fishes will die and it can certainly harm fishermen who want to catch the fishes. Read more about Fishes in Atlantic Ocean

5. The global warming

The global climate can also increase the potential of the abrasion on the shorelines. The increasing of the temperature of the earth can melt the poles where this causes an increase in the sea level rise. This rising sea level is the cause of the abrasion on the shorelines.

This climate change can also cause the high waves and storms. The climate change also can reduce the number of the fishes and shrimps populations in the sea. Read more about  How to Reduce Global Warming Effects in Ocean

6. The sand mining on the shorelines

Abrasion on the shoreline can also occur due to human intervention. Some people legally mine on the sand on the coastal areas upstream that empties into the coastal area. This sand mining activity will make the coastal position lower than the sea. The result of abrasion of the sand mining can also erode the coastal areas for as far as tens of kilometers.

In addition, due to sand mining also impact on the village road because it will suffer damage. Roads in the village of manufacture are not as solid as the highway. While the vehicle carrying sand every day through the village. This heavy vehicle that causes the road to the village to be damaged.

7. The construction on the adjacent coastal areas

Who does not like to travel beach, surely everyone likes it, right? Every time that we visit the beach we also find many hotels or residential areas nearby the shorelines. This human factor is the one that influences of coastline changes. The construction of settlements and tourist attractions can lead to more severe abrasion.

Especially with the rising of the several tourism accommodation developments such as hotels, resorts and villas are also the main cause of abrasion. If the development around the coast is not restricted, the water will overflow and it can enters. Even it can destroy the residence of some residents who live at the coastal areas.

8. The construction of ponds that do not productive and conducive

Deforestation of mangroves is usually done to be converted into ponds. Even sometimes the land used to build a pond is not productive and conducive. This is what causes the pond area will have a negative impact on the coastline.

Gradually abrasion will erode coastal areas, even this phenomenon can destroy homes and even turtle conservation sites in it. The unconsciousness of the community about the dangers of unproductive pond land is a big problem. Until now the ponds are located in an environment that is not conducive is still a pro and cons in the society.

9. The waste in the adjacent coastal areas

Beaches that have many tourists sometimes leave a lot of garbage, especially plastic waste. Various garbage scattered along the shoreline is also the cause of the abrasion. The waste that scattered on the beach can disrupt a number of activities, such as on a seaweed farmers up to the fishermen.

The water abrasion on the beach can affect the trees along the coastline collapsed. The coastal abrasion can also spend some coastal areas and it always leaves the tree roots that collapsed.

10. Build a breakwater

The first solution that can reduce the phenomenon of abrasion is building the breakwater. The breakwater walls are built to break the waves by absorbing some of the ocean wave energy. With this abrasion walls, the eroding of this shoreline will be well controlled.

These breakwaters also serve to calm the waves at the harbor, so the ship can be anchored to the port more easily. However, this breakwater wall solution takes a lot of cost and time. In fact, the increasingly severe abrasion has even made some walls collapse due to erosion by large waves continuously.

11. Replanting of mangroves

Planting mangrove trees are the better solution. Mangrove trees are also often said to be coastguards from the dangers of abrasion. Some beaches do have some mangrove trees but only a small part. Many mangrove trees are damaged by the development of coastal land for commercial purposes. Did you know? in the presence of mangroves can help stabilize of the coastline.

This stability must be maintained so that the coastal area is not eroded and does not damage the lives of living things around the coastline. Aside from being a lifeguard, mangrove forests can also prevent natural disasters such as tsunamis. Even with the mangrove tree is also used by some marine animals as a place of the nursery ground.

12. Keeping clean at the shorelines

A simple solution to prevent abrasion is to keep the shoreline clean. Plastic waste is the waste that is often found along the shoreline. Usually, the plastic debris is scattered or floated and it will be eaten by birds and fishes that live around in the shoreline.

The way to keep the shoreline clean is to avoid drinks or packaged foods, switch to the tumbler and boxes. If you want to throw away the trash, but there is no garbage dump. You can put them in the plastic, take the garbage until you find a place to throw away the trash. So, no reason to throw away on the sea, right?

13. Reduce the plastic and household waste

The wastes we usually find on the coast are not just from tourists, the residential populations, where trading of government-owned facilities, various industries, and agriculture are also the factors of the arrival of waste.

What is the best solution to keep beach free from these? The first method is to reuse used goods, repair damaged items for reuse such as making shopping bags. The second method is to pollute the appropriate types of waste such as plastic or inorganic waste, and household waste or organic waste. Usually in garbage collection has been provided by local government agencies or private companies. Read more about How to Prevent Plastics in the Ocean

14. Do not sell any marine ornaments as souvenirs

Some people use the coral reefs to be used as souvenirs. Coral reefs are shearing protectors from the waves, it is a place for any marine animals that live in it and it is the balance of the ecosystem in the sea. The humans do not take only the coral reefs, other sea creatures such as bloated fish, shellfish are also preserved to be a souvenir.

If coral reefs are continuously taken without any replanting, the abrasion will occur and the worse is it can cause of phenomena such as tsunami waves.

15. The role of society on adjacent coastal abrasion issues

The importance of society’s role is most influential here. Without a high awareness of the community to maintain the area on the coastal areas, the environment will not be free from the problems that exist. Health is a very valuable thing, by keeping our environment avoided from things that harm.

Conversely, a dirty environment will be a health hamper and it will bring disease. With a little awareness of the community from every individual or group of people is important to preserve the natural environment in which there are also important living beings and all of that creatures also to be preserved.

Hopefully, with the explanation of the 15 effects of ocean currents on adjacent coastal areas on above can make us aware to care more about the environment around us. Who else should preserve and protect the earth if not us? Just we are as human beings whose care about the surrounding environment.
