Abstract Wave energy gradients between and along the margins of inlet channels play an important role in defining the inlet margins’ evolutionary processes, mainly those related to spit erosion or accretion, and inlet migration. The aim of this study is to understand the wave power distribution along the margins of a tidal inlet (Cananéia inlet, São Paulo, Brazil), its variation over time, and the influences of the ebb tidal delta morphology on the incoming waves. To evaluate changes in bathymetry and morphology of submersed features, we apply geoprocessing techniques to analyze nautical charts from the Brazilian Navy from 1939, 1971, 1985 and 2004. The numerical model MIKE21 SW was applied to assess wave propagation and nearshore wave power. Hence, wave... |

A comparative study involving three mesotidal beaches from reflective to estuarine states was conducted between October 2010 and September 2011 in the estuary of Mamanguape River, northeastern Brazil. The aim was to test for differences in fish assemblages along a morphodynamic continuum, particularly the effects of wave action. In total, 3,732 fish from 71 species were examined; Rhinosardinia bahiensisand Atherinella brasiliensisdominated the estuarine beach, whereas Trachinotus carolinus dominated the reflective beach. Fish assemblages were structured by spatial differences among the sites, and overall abundance, richness and biomass demonstrated a clear increasing trend from the reflective to the estuarine beaches, indicating a primary influence of wave... |

Les plages de la côte nord de Mahdia sont structurées par deux types de barres sableuses : festonnée aux extrémités nord et sud du prisme sableux de la baie, et rectiligne vers le centre. Cette thèse a pour objectif de décrire la morphologie de ces formes sédimentaires modelées par les processus hydrodynamiques. La forme tridimensionnelle des barres sous-marines a pu être décrite à partir des mesures bathymétriques. L’application d’un modèle numérique de propagation des houles (SMC) montre la résultante du couplage entre l’hydrodynamique littorale en présence de vagues déferlantes et la dynamique sédimentaire des courants de fonds afin d’analyser la morphodynamique des bancs de sable. Le suivi spatio-temporel de l’évolution morphologique de la plage... |
