Overwash and ocean flooding in Portugal: case study of Fonte da Telha, Costa da Caparica

Abstract

Povoações costeiras em Portugal são atingidas frequentemente por tempestades, algumas das quais são capazes de induzir galgamentos, levando a inundações severas. Este estudo foca-se nos potenciais danos que a povoação de Fonte da Telha pode sofrer na ocorrência de inundações por galgamento oceânico. Dos 222 elementos identificados na povoação, cerca de 70% está na faixa de risco de inundação. Áreas de ocupação do solo definidas por Praias e Floresta de espécies invasoras são totalmente abrangidas pela área de risco. De modo a combater o presente cenário, foi realizado um Plano de Pormenor, definindo os 11m como a altitude mínima para construção de edificado.

Coastal settlements in Portugal are routinely hit by storms, some of which produce significant overwash, leading to severe floods. In this study we focus on the possible damages Vale da Telha settlement could incur in the event of severe overwash and flooding following a storm. It was found that of the 222 elements comprising the settlement, roughly 70% were at risk of flooding. Most of the areas classified as Beaches and Invasive species forest are within the risk area. To reduce this scenario, artificial construction should not be carried out below the 11m altitude threshold.
