Abstract

This study focuses on the dominant Faro-Olhão and Armona inlets in the Ria Formosa barrier island system of southern Portugal. The equilibrium state and future evolution of the system are inferred using a range of morphological and hydrodynamic indicators, including the evolution of the inlet cross-section, changes in tidal prism, and changes in the dimensions (length and area) of barrier islands. The results reveal how the morphology of an interconnected two-inlet bay system and the adjacent coastlines has evolved following the artificial opening and stabilization of Faro-Olhão inlet since 1929. A clear relationship between barrier island size, inlet cross-section/width, and tidal prism is demonstrated. The work highlights the importance of ebb-tidal deltas both as sand reservoirs and as conduits through which sand exchange between estuaries or lagoons and the open coast is regulated.
