Resumo: This dissertation has the main purpose of analyzing the Nazaré canyon influence in the region´s maritime agitation trough the application of the SWAN (Simulating WAves Nearshore) mathematical model. To understand the impact of the Nazaré canyon, a synthetic scenario was defined, apart from the real scenario, where the Nazaré canyon was completely fulfilled with sediments and the numerical bathymetry was modified, using a tool from the MOHID modeling system, in a way that the seafloor was like a normal beach brake. The SWAN model was applied for several different forcing conditions and it were analyzed the height, period, direction, length and orbital speed´s results. The results of the simulations performed by SWAN along the Nazaré coast, in different scenarios, confirm the importance of the Nazaré canyon in the wave circulation in this region. In general, all parameters had specific changes, but the changes in wave direction, wave height and orbital velocity, are the ones that showed differences that would cause a highest impact on the wave circulation in the region.

Para entender efetivamente o impacto do canhão da Nazaré, para além do cenário real foi criado um outro cenário onde o canhão da Nazaré foi completamente preenchido por sedimentos e a batimetria numérica foi alterada, com o uso de uma ferramenta especifica do sistema de modelagem MOHID, de modo que o fundo oceânico fosse como um “beach brake”. O modelo SWAN foi aplicado com diversos forçamentos diferentes, e foram analisados os resultados de altura, período, comprimento e direção de onda, além da velocidade orbital. Todos os resultados analisados apresentaram mudanças significativas de valores após a alteração na batimetria, o que mostrou a enorme influencia do canhão da Nazaré na agitação marítima, tanto na praia do Norte como na praia da Nazaré. As mudanças na altura e direção das ondas e na velocidade orbital, são as que apresentam maior intensidade e como tal as que causariam uma maior alteração no regime de agitação da região.Universidade de Aveiro2015-08-18T11:09:33Z2014-01-01T00:00:00Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/14537TID:201573377engForone, Eduardoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:26:35Zoai:ria.ua.pt:10773/14537Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T02:50:06.731613Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
