Abrasion

Definition of Abrasion

Abrasion is a process of deformation of the coast or coastal erosion caused by ocean waves, ocean currents and tides. Abrasion that occurs continuously will cause damage to the environment. According to news from the newspaper "Mind of the People" on May 31, 2004, the so-called 40 kilometers of coastal area in Indramayu Regency continued to be eroded. Damage due to sea water which is spread in seven districts in Indramayu is very alarming.

Process of Abrasion

The process of abrasion due to natural factors is caused by winds blowing over the ocean which causes waves and ocean currents so that it has the power to erode the coast. The waves that arrive at the beach can vibrate the soil or rocks which will eventually be separated from the mainland.

The picture above shows the direction of the ocean waves that erode the coast. The waves that arrive at the beach can vibrate the soil or rocks which eventually get separated from the land like a small earthquake

Impact of Abrasion

Negative impacts caused by abrasion include:

Depreciation of the beach width is narrowing it for residents living on the beach

Damage to the mangrove forests along the coast, due to the waves that drive strong winds so big.

Loss of fighting place for fish due to erosion of mangrove forests

Factors contributing to beach abrasion:

 1. Nature's factors. A natural phenomenon that causes the beach's erosion of tides as well as ocean breezes that produce strong waves and currents. 

2.  Ground level rise. Excessive water intake results in soil degradation, causing land to become lower than the oceans. This certainly increases the risk of rob's flood because it pours seawater onto land. 

3.  Destruction of mangrove forests. Coastal communities cut down mangrove forests to be shot. Moreover, the timbers of mangrove trees are also sold for building foundations. These activities interfere with regeneration and disrupt the process of mangrove forests. It also caused abrasion, and the loss of some of the island's ecosystems. 

4.  The ravages of human activity. The human activities that have caused beach erosion are in the form of sand mining, pollution of inorganic debris and the mining of coral reefs. 

5.  Global climate change, often referred to as global warming. Rising earth's temperature is causing polar ice caps to melt. When polar ice caps melt significantly, it will cause rising sea levels to rise, causing them to scour the land as low as the coast.
