celerity

Geology and Earth Sciences

Velocity with which a wave advances. The celerity (c) of an ideal wave is related to its wavelength (λ‎) and frequency (f) by the wave equation c = fλ‎. The wave frequency (f) is the number of waves (n) passing a point in unit time (t), i.e. f = n/t. In deep water the wave celerity may be calculated by the equation: c = (gλ‎/2π‎)^½ = 1.25√λ‎, where λ‎ is the wavelength in metres and g is the acceleration due to gravity (9.81 m/s²). The speed of shallow water waves may be calculated by the equation: c = (gd)^½ = 3.13√d, where d is the depth of water in metres.

Geography

In a river, the square root of the product of the acceleration due to gravity and the mean depth of the river flow. See Richardson and Carling (2006) Geomorph. 82, 1–2.
