SHORELINE PROTECTION SCHEME AT CONCEICAO DA BARRA,BRASIL

摘要

During several years severe beach erosion was observed at the city of Conceicao da Barrain the state of Espirito Santo, Brazil. The beach erosion is caused by a gradual increase inlittoral sediment transport towards North, which has caused a shift in the direction of thenet littoral drift. A new shoreline protection scheme was developed and tested. Thescheme is based on two main principles: 1) - Create a number of sub cells in which theshoreline can attain its equilibrium orientation and 2) - Enhance the volume of sand ineach cell in order to allow the natural shoreline dynamics due to cross-shore sedimenttransport.
