"Diffusivity is also sometimes known as the coefficient of diffusion. Diffusion occurs as a result of a gradient in the spatial distribution of mass concentration, temperature or momentum. The diffusivity may be very different in the vertical and horizontal directions. \"Bolus diffusivity\" means a lateral diffusivity. \"biharmonic diffusivity\" means diffusivity for use with a biharmonic diffusion operator."@en .
