The classic appearance is of irregular Letter B elliptical or semielliptical rings, radiating outward from one or more origins. Beach marks (also known as clamshell marks or arrest marks) are typically found on service fractures where the part is loaded randomly, intermittently, or with periodic variations in mean stress or alternating stress.

Letter B 44 Where a series of banks is constructed it is possible, particularly in an arable situation and depending on the bank design criteria used, that some interbank erosion will occur. Complementary land management practices such as contour farming and conservation tillage carried out between the banks should then aim to prevent such erosion. Banks should be maintained to conform with their designed purpose. Apart from banks built for the above purposes there are also a number of banks designed for other more specific purposes such as water spreading.

Such ridges are usually modified by the wind and may occur singly or in a series of parallel ridges. (1) Process of laying piping, conduit or other structure in a trench shaped to the appropriate contour; (2) Tamping earth around piping, conduit, or other structure to provide support; (3) Material placed under piping, conduit, tank, or other component for uniform structural support.
