Resumo: | Field data based information on the coastal sediment dynamics becomes even more relevant for coastal managers in the present context of climate changes. Due to the sea level rise and the increase of frequency and intensity of coastal storms, coastal managers need to implement effective and efficient solutions for increasing coastal resilience, namely through reprofiling the beach for restoring the sediment balance and providing space for the beach natural dynamics. The study characterises and quantifies the morphological changes in an Atlantic urban sandy beach under extreme wave energy and sea level conditions. The erosion of the foreshore and backshore of this particular beach was characterised as function of the intensity and duration of the hydrodynamic forcing parameters (waves and sea level). This 24-hour duration storm event, which delivered to the beach a total energy of 1.7x109 J, caused the seaward displacement by the undertow current of approximately 3x103 m3 of median well sorted sand from the beach foreshore and backshore. |

Devido à subida do nível do mar e ao aumento da frequência e intensidade de tempestades marítimas, os gestores costeiros necessitam de implementar soluções eficazes e eficientes para melhorar a resiliência costeira, nomeadamente através do reperfilamento da praia para restabelecer o balanço sedimentar e conceder espaço para a dinâmica natural da praia. O estudo caracteriza e quantifica as variações morfológicas numa praia arenosa, urbana e Atlântica sob ação de condições extremas de energia das ondas e nível do mar. A erosão da face e do topo da praia foi caracterizada em função da intensidade e duração dos parâmetros forçadores hidrodinâmicos (ondas e nível do mar). Este evento de tempestade com duração de 24 horas, que transmitiu à praia uma energia total de 1.7x109 J, causou a extração de aproximadamente 3x103 m3 de areia média da face e do topo da praia e o seu transporte pela corrente de retorno para maiores profundidades.Associação Portuguesa dos Recursos HídricosRepositório da Universidade de LisboaOliveira, Filipa S.

Field data based information on the coastal sediment dynamics becomes even more relevant for coastal managers in the present context of climate changes. Due to the sea level rise and the increase of frequency and intensity of coastal storms, coastal managers need to implement effective and efficient solutions for increasing coastal resilience, namely through reprofiling the beach for restoring the sediment balance and providing space for the beach natural dynamics. The study characterises and quantifies the morphological changes in an Atlantic urban sandy beach under extreme wave energy and sea level conditions. The erosion of the foreshore and backshore of this particular beach was characterised as function of the intensity and duration of the hydrodynamic forcing parameters (waves and sea level). This 24-hour duration storm event, which delivered to the beach a total energy of 1.7x109 J, caused the seaward displacement by the undertow current of approximately 3x103 m3 of median well sorted sand from the beach foreshore and backshore. |
