A coast – also called the coastline, shoreline, or seashore – is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. [1] [2] Coasts are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves.
Port Campbell in southern Australia is a high-energy shoreline. The waves of different strengths that constantly hit against the shoreline are the primary movers and shapers of the coastline. Despite the simplicity of this process, the differences between waves and the rocks they hit result in hugely varying shapes.
This was the beginning of the coastline problem, which is a mathematical uncertainty inherent in the measurement of boundaries that are irregular. [6] The prevailing method of estimating the length of a border (or coastline) was to lay out n equal straight-line segments of length l with dividers on a map or aerial photograph. Each end of the ...
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.
OAHU, Hawaii — Hawaii’s most famous coastline, Waikiki Beach, is not going to be the same in the next 50 years. ... These types of barriers are known as shoreline hardening, a manmade way to ...
The coastline paradox states that a coastline does not have a well-defined length. Measurements of the length of a coastline behave like a fractal, being different at different scale intervals (distance between points on the coastline at which measurements are taken). The smaller the scale interval (meaning the more detailed the measurement ...
* New York has both ocean and Great Lakes coastline. This is a list of U.S. states and territories ranked by their coastline length. 30 states have a coastline: 23 with a coastline on the Arctic Ocean, Atlantic Ocean (including the Gulf of Mexico and Gulf of Maine), and/or Pacific Ocean, and 8 with a Great Lakes shoreline.
In Greece, according to the L. 2971/01, the foreshore zone is defined as the area of the coast that might be reached by the maximum climbing of the waves on the coast (maximum wave run-up on the coast) in their maximum capacity (maximum referring to the "usually maximum winter waves" and of course not to exceptional cases, such as tsunamis ...
