We present a new empirical shoreline evolution model integrating longshore and cross-shore processes. It is designed for wave-dominated sandy coasts and includes feedback between shoreline and wave dynamics. It can also take into account non-erodible (e.g. rocks, artificial structures) contours and complex wave propagation patterns through the coupling with the spectral wave model SWAN. While t...
BACKGROUND: Under the assumptions of longshore uniformity, monochromatic and unidirectional waves, one-dimensional (1-D) models have predicted the steady depth-integrated longshore current with reasonable accuracy in the regions of intense breaking (e.g., Bowen 1969; Longuet-Higgins 1970; Kraus and Larsen 1991). The addition of random wave fields with directional spread (Battjes 1974; Thornton ...
This study applies some of the most practical longshore sand transport formulations and evaluates their adequacy to estimate the total (suspended and bed load) longshore sediment transport rate (LSTR) at Buarcos Beach, in the West coast of Portugal. The straightforward methodology here present is simple to apply and therefore useful to quickly obtain a first estimate of the littoral transport i...
