Scientists are concerned about changes in Chile’s coastline over the past 40 years. high levels of erosion and rising sea levels product of Climate change,
as stated What are you saying?Coastal erosion affects 86% of beaches between Arica and Chiloé.A phenomenon that doubles every two years.
Carolina Martínez, director of the Observatory of the Coast, told the media that “the beaches with the highest rates of erosion correspond to Ensenada, where Extensive sandy shorelines have developed, linked by ancient dune fields and coastal wetlands”.
Due to the above, there are many beaches that have a high level of tremors in its coasts of more than 1.5 meters per year of which are:
- Hornitos (R. antofagasta)
- Tongoy (R. Coquimbo)
- carob tree (R. valparaiso)
- Horcon (R. Valparaiso)
- Cartagena (R. Valparaiso)
- Los Moles (R. Valparaiso)
- Santo Domingo (R. Valparaiso)
- puertecillos (R. O’Higgins)
- Pichilemu (R. O’Higgins)
- Matanzas (R. O’Higgins)
- Lebu (R. biobio)
according to the bookTowards a Coastal Law: Basis for Integrated Management of Coastal Zones“One of the most worrying cases is that of Algarrobo Bay, because Intense swelling present in place since 2015, recording a retreat of up to four meters per year.
Along the same lines, Martinez speculated in the aforementioned medium that “Areas of greatest erosion by 2042 will be north and south of the bay, affecting Cartagena wetlands and El Tabo beach,
The publication also maintains that although tidal waves have always been recorded for many years, their potential impact is enormous Due to the rapid urban, economic and demographic growth of our country.
Apart from the above, the procedures of Climate change, prolonged drought and human interference have directly affected the supply of sediment to beachesWhich is carried along the coast by waves, ocean currents or river flow.
