This paper discusses the influence of selected methods of deriving the deposition velocity of aerosols falling from the atmosphere into the water in the coastal zone. The three methods pro-posed by Sehmel and Sutter (1974), Slinn and Slinn (1980) and Carruthers and Choularton (1986) are presented. The similarities and differences of the methods are discussed, as are the influence of the deposition velocity on aerosol fluxes, and the importance of physical parameters on aerosol transport.
