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 ...
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 ...
The Bruun rule gives a linear relationship between sea level rise and shoreline recession based on equilibrium profile theory, which asserts that shore face profile maintains an equilibrium shape, and as sea level rises the increasing accommodation space forces this equilibrium profile landward and upward to preserve its shape relative to the new sea level.

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.
In localities where the coastline is deeply indented and cut into, or if there is a fringe of islands along the coast in its immediate vicinity, the method of straight baselines joining appropriate points may be employed in drawing the baseline from which the breadth of the territorial sea is measured.
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.
Defining the shoreline is a difficult task due to its dynamic nature and the intended application. [25] [26] The relevant mapping scale is dependent on the context of the investigation. [26] Generally, the coast comprises the interface between land and sea, and the shoreline is represented by the margin between the two. [27]
* 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.
