Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
Mangroves in India are coastal ecosystems characterized by salt-tolerant trees and shrubs, found predominantly along the eastern and western coastlines and in the Andaman and Nicobar Islands. India hosts some of the largest mangrove forests in the world, including the Sundarbans, Bhitarkanika, and the Krishna-Godavari delta regions. [ 1 ]
Coastal India is a geo-cultural region in the Indian subcontinent that spans the entire coastline of India. [1] Indian total coastline is estimated to 11,098 km. [2] Gujarat has the longest coastline with 2340 km. Second longest coastline belongs to Tamilnadu with 1068 km. Andhrapradesh comes third with 1053 km. West Bengal has the 721 km ...
Murkata village in the northeastern state of Assam is in one of the most climate-vulnerable regions of India, according to a report by the Council on Energy, Environment and Water, a New Delhi ...
Active flow only lasts for about two months, and the sediment load is similarly diminished. Saline water intrudes upstream for about 80 km (50 mi) and this affects both the mangroves growing in the area and the agricultural land. Loss of sediment causes increased coastal erosion, and this is exacerbated by land subsidence and rising sea levels ...
The Western Coastal Plains is a stretch of coastal land lying between the western edge of the Deccan plateau and the Arabian Sea in the west. [1] [2] The plains stretch from the Rann of Kutch region to Kaniyakumari at the southern tip of the Indian peninsula. The average width of the plains vary between 50–100 km (31–62 mi).
Coastal erosion along the Thiruvananthapuram coastline has caused significant reduction in the beach area. A study from 2022 found that the region including the Shankumugham beach observed an erosion of 4.73 meters per year. [10] The Shankumugham-Airport road along the beach was closed due to excessive erosion. [11]
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
