  2. Coastal India - Wikipedia

    en.wikipedia.org/wiki/Coastal_India

    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]

  3. Coastal erosion - Wikipedia

    en.wikipedia.org/wiki/Coastal_erosion

    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.

  4. Sedimentary budget - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_budget

    Diagram of accretion and erosion of sediments in a coastal system. Black arrows indicate accretion, and white arrows indicate erosion. Sedimentary budgets are a coastal management tool used to analyze and describe the different sediment inputs (sources) and outputs (sinks) on the coasts, which is used to predict morphological change in any particular coastline over time.

  5. Shankumugham Beach - Wikipedia

    en.wikipedia.org/wiki/Shankumugham_beach

    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]

  6. Marine coastal ecosystem - Wikipedia

    en.wikipedia.org/wiki/Marine_coastal_ecosystem

    A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.

  7. Coral reefs in India - Wikipedia

    en.wikipedia.org/wiki/Coral_reefs_in_India

    Coral reefs in India are one of the most ancient and dynamic ecosystems of India. The coral reefs not only provide a sanctuary to a myriad of marine life but also play a key role in protecting the coastline from erosion. India has about 7517 km of coastline including islands but mainland coast is 6100 km. [citation needed]

  8. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Techniques for measuring erosion and denudation include stream load measurement, cosmogenic exposure and burial dating, erosion tracking, topographic measurements, surveying the deposition in reservoirs, landslide mapping, chemical fingerprinting, thermochronology, and analysis of sedimentary records in deposition areas. [26]

  9. Beach evolution - Wikipedia

    en.wikipedia.org/wiki/Beach_evolution

    Structural erosion is due to sea-level rise relative to the land and, in some spots, it is caused by harbour dams. The Dutch coast looked at as a single unit shows erosive behaviour. Approximately 12 million m³ of sand is transferred annually from the North Sea to the Wadden Sea as a result of relative rising sea level and coastal erosion.
