Sea Erosion Swallowing 9 kms Annually on East Coast. At last, it is official that the main advantage of Andhra Pradesh, the 973.3 km coast line on the East Coast is facing sea erosion, presently at 9.2%, that is roughly 9 kms of coast line is being swallowed by the sea which in other words means 2223.95 acres per annum.

At last, it is official that the main advantage of Andhra Pradesh, the 973.3 km coast line on the East Coast is facing sea erosion, presently at 9.2%, that is roughly 9 kms of coast line is being swallowed by the sea which in other words means 2223.95 acres per annum. Breakwaters and absence of sea corals that can cut the breakwaters are said to be the main cause of sea erosion on the East Coast.

Oceanography experts have identified that heavy erosion was noticed at Uppada in East Godavari, Vizag and Bheemunipatnam beaches in Visakhapatnam district. As per reports, about 23 per cent of the shoreline along the Indian mainland is affected by erosion.Oscillation of the shoreline along the Indian coast is seasonal and some of the beaches revert to their original profiles by March or April. But, unfortunately, 50 per cent of the beaches that do not regain their original shape over an annual cycle undergo erosion.

Seashore erosion in the east coast regions of Chennai, Ennore, Visakhapatnam and Paradip ports is due to construction of breakwaters (structures made on coasts to protect the area where sea vessels lay their anchors from the effects of the weather) for the respective port.

According to studies, the AP coast has frequently been affected by Cyclone and inundated by storm and Tsunami surges. The tsunami in 2004 and various cyclones, including Phailin and Hudhud, have drastically changed the beach profiles making them vulnerable to erosion. Many coastal areas along the AP coast are now distorted with the changed landscape and soil culture scenario, say studies.

The National Institute of Ocean Technology, Chennai, which has been conducting studies on erosion along the city beaches, has suggested dredging operations as a short-term measure and placing offshore-submerged breakwaters as a long-term procedure.

The National Institute of Ocean Technology(NIOT) has conducted vast studies and interacted with the city’s port and other organizations on east coast and is submitting a report by mid June and also developing a pilot model to address the problem.
