Contributos para a revisão do plano de ordenamento da orla costeira na região Centro

Abstract

The Ovar - Marinha Grande coastal management plan will be updated in a very near future. This coastal stretch is under a strong erosion process and several urban settlements are under risk situation. On a medium and long term basis it is not clear to consider a clear border between climate change and climate variability since the high wave energy exposed coast has always experienced strong morphologic changes. Anthropogenic actions (harbour breakwaters, dredging works, river damming) are very important and have induced erosion problems due to a negative sediment balance. After the presentation of key issues (coastal protection works, coastal dynamics evolution, harbour expansion), several management challenges are discussed and proposals are submitted. Keywords: Coastal management, challenges, coastal erosion, anthropogenic actions, climate change, climate variability.
