Nat. Most of Japan is threatened by flooding and high waves during the typhoon season around September. Yet, how sandy coasts respond to these basin-scale changes has to date been limited to a few long-term beach monitoring sites, predominantly on developed coasts. 44, 24162426 (2017). As hypothesized, the west coast has been the most impacted by human development. A 24-hectare dry beach has been created along a breakwater to replace the dry beach at the mouth of a river which was been lost to harbor development. https://doi.org/10.1016/j.earscirev.2016.07.011, https://doi.org/10.1016/j.geomorph.2021.107707, https://doi.org/10.9753/icce.v36v.papers.65.

Read our affiliate link policy. Japan has established no ICZM system for maintaining the integrity of the coastal zone. By contrast, La Nia events coincide with significant accretion for approximately one-quarter of all transects, although substantial erosion is observed in southeast Australia and other localized regions. 13, 12431265 (1993). As a result, it is vital to protect these ecosystems. There are other concerns about breakwater barriers, too, like whether or not they have the potential to slowly increase sediment deposits by washing down the coast bit-by-bit, in turn actually increasing erosion. A wide variety of structures have been built in Japan with the express purpose of preserving coastal areas against the above-discussed problems of typhoon-flooding, tsunamis, and slow coastal erosion. Influence of the state of the Indian Ocean Dipole on the following years El Nio. Process. & Yu, J. Y. A multi-decade dataset of monthly beach profile surveys and inshore wave forcing at Narrabeen, Australia.

There are numerous other examples of restoration of the environment and creation of new environments in Japans coastal zones. And with the earthquake that occurred this week in Fukushimaan aftershock of 2011, experts believethis effort seems more pressing than ever. Lett. Comparison of those cities, towns, and villages which border coast lines with those which are landlocked in terms of their area, population, value of industrial shipments, and value of commercial sales shows that despite the fact that waterfront municipalities do not exceed 32% of the total area, they account for 45% of the population, 47% of the value of industrial shipments, and 77% of the value of commercial sales. Erosion and Accretion: Erosion and accretion are complementary to each other. This makes the areas extremely vulnerable. This underscores the fact that human activity in Japan has reached a level where its impact on coastal zones can not be ignored.
