Sažetak
Simple coagulation and sedimentation mechanisms are considered in relation to the sea particle size distribution (PSD). It is shown that the values of γ-parameters in the two-component model of PSD can be associated with coagulation and sedimentation mechanisms. Moreover, it is shown that low γA-values can be associated with high turbulent kinetic energy dissipation rate characteristic of surface and coastal waters. High γA-values, characteristic of deep waters, indicate domination of differential sedimentation over shear coagulation. An insight into the size ordering of mechanisms and the extent of size sub-range in which they dominate can be inferred from generalized power exponent m(r) which is γ-parameter dependent.
