The harbour Portinho da Aguda was established between October 2001 and July 2002, at Aguda village. The area presented some rocky outcrops that, in some way, protected the coastal border against direct wave impact, on a coastal stretch where erosion has been a continuing problem. In an attempt to create a protected area for the entrance and way out of the community’s small fishing boats a detached curved breakw...
Na zona costeira do noroeste de Portugal os processos erosivos em curso têm vindo progressivamente a constituir motivo de preocupação, quer para os responsáveis pela gestão da zona costeira, quer para a população em geral. As principais causas apontadas para a origem destes processos são: (i) diminuição dos caudais sedimentares fluviais, devido à construção de barragens, dragagens, extracção de inertes e esgota...
A zona costeira do noroeste de Portugal tem vindo a sofrer processos erosivos de modo progressivo que têm preocupado os responsáveis políticos e os cidadãos em geral. Esta realidade é especialmente notória nas zonas costeiras com altas pressões de ocupação. A zona costeira de Vila Nova de Gaia apresenta ocupação intensa, tendo vários segmentos que evidenciam elevada vulnerabilidade à erosão costeira. Com o obje...
Apresenta-se, de forma sumária, o Projecto FMI 5000 – Enviromental Changes: Fluvio-marine interactions over the last 5000 years (Projecto FCT no: PtDC/ Cte-GiX/104035/2008). Os ambientes estuarinos constituem uma das áreas mais sensíveis, no quadro das alterações climáticas e da subida do nível do mar, porque se situam na interface entre as influências fluviais e marinhas e são o suporte, não só de áreas húmida...
Sediment dynamics in the vicinity of river mouths reveal complex patterns due to the joined effect of river discharges, tides and waves. These phenomena underlie current mathematical and simulation models, which constitute powerful tools that can be used as a complement to monitoring field work for the characterization of morphodynamical patterns in these complex coastal environments. The Cávado estuary inlet i...
During the last three years geoscientists of various institutions have developed a project aiming the setup of a geoconservation strategy in Portugal (Brilha, 2009). One of the main goals of the project was the establishment of an inventory of the most important Portuguese geosites, under the scientific point of view. In a near future, national authorities will consider this inventory as a technical support for...
This work constitutes the first contribution for the systematisation of the geological heritage knowledge in Portugal, following the international recomendations for the characterisation of geological heritage (IUGS, ProGEO). The application of the ProGEO methodology has resulted on the creation of fourteen frameworks with international relevance, established by consensus among the Portuguese geological communi...
The Cávado estuary inlet is situated in the coastal zone of Esposende (NW Portugal) where sandy beaches have migrated inland and thinned, and cliffs have retreated rapidly over the last years. The coastal zone of Esposende extends over 15 km from the Neiva River until Apúlia. The coastal segment of Esposende can be considered of mixed energy and wave-dominated type, according to DAVIS and HAYES (1984). The loca...
