ABSTRACT
Integrated coastal zone management techniques usually search the preferences of the owners of the coastal properties but without considering the beach users. Multipurpose artificial reefs are submerged structures built in order to diminish wave action, to modify breaker conditions, to protect the coast, and to increase marine biodiversity. Alternatives construction types are considered in relation to the surfing quality of the waves of Mar del Plata. Although detached emerged breakwaters and low-crested submerged structures have been successfully applied to protect beaches from breaking waves, the artificial surfing reefs can improve breaker conditions for recreational purposes. Both structures may increase sand accumulation at the beach if it is naturally available; if not the beaches should be artificially nourished. Based on knowledge of the littoral transport and the bottom composition of the Ensenada Mogotes, artificial submerged reefs, combined with nourishment efforts, are proposed to recover the beach called Los Acantilados. The surfing conditions can improve as a surplus to the stability of the rocky-sandy nearshore ecosystem.

RESUMO
As técnicas de gestão integrada da zona costeira são normalmente direccionadas para a protecção dos interesses dos donos das propriedades costeiras e menosprezam, ou não consideram, os interesses dos utentes das praias. Os recifes artificiais multi-funcionais são estruturas submersas construídas para mitigar ou reduzir a acção das ondas, modificar/melhorar as condições de rebentação, proteger a zona costeira (em particular, campos dunares e praias) e aumentar a biodiversidade marinha. São abordadas construções alternativas relativamente à qualidade das ondas para a prática de surf em Mar del Plata. Embora construções clássicas como quebra-mares destacados e estruturas submersas tenham revelado sucesso na protecção da praia, os recifes artificiais multi-funcionais permitem melhorar as ondas para a prática de surf e outros fins recreativos. Ambos os tipos de estruturas promovem alguma acumulação de areia na praia, se esta estiver naturalmente disponível; não existindo, a praia deverá ser alimentada artificialmente. Com base no conhecimento do transporte litoral e na composição dos fundos da Mogotes Ensenada, é proposta uma solução de recifes artificiais submersos, eventualmente combinada com alimentação artificial, para recuperar a praia de Los Acantilados. As condições de surf deverão melhorar e espera-se uma contribuição positiva para a estabilidade do ecossistema arenoso existente.
