Abstract

The study is aimed at determination of magnitudes and directions of sediment fluxes along the coasts of Sambian Peninsula and Curonian Spit by using the calculations of wave-induced sediment transport in a coastal zone. On the base of available data on nearshore bathymetry and wave regime the distributions of both the total fluxes for main wave directions and net sediment flux are computed. It is shown that sediment transport along the studied coasts break up into a number of cells with alternating zones of divergence and convergence. Unidirectional sediment flux is traced only in the northern section of Curonian Spit (up to 260×10³ m³/year). Predicted location of the erosion and accretion zones associated with changes in the net sediment flux is confirmed by the published observed data.
