| ABSTRACT The backshore zone is transitional environment strongly affected by ocean, air and sand movements. On dissipative beaches, the formation of ephemeral dunes over the backshore zone plays significant contribution in the beach morphodynamics and sediment budget. The aim of this work is to describe a novel method to identify ephemeral dunes in the backshore region and to discuss their morphodynamic behavior. The beach morphology is identified using Argus video imagery, which reveals the behavior of morphologies at Cassino Beach, Rio Grande do Sul, Brasil. Daily images from 2005 to 2007, topographic profiles, meteorological data, and sedimentological parameters were used to determine the frequency and pervasiveness of these features on the backshore.... |

| Se presenta en este artículo una metodología a través de la cual se determina cuantitativamente el efecto en la hidrodinámica del golfo de Urabá de un grupo de procesos costeros y forzamientos externos, los cuales, inicialmente, se asumen relevantes en el comportamiento del flujo. De acuerdo con este propósito, se realiza la simulación numérica del flujo y el oleaje en el golfo a través de la plataforma de modelación Delft3D. La modelación considera los siguientes procesos: (i) la influencia marina a través del forzamiento de la marea en la frontera norte del golfo; (ii) el oleaje; (iii) la estratificación termo-salina; (iv) el arrastre del viento y (v) la influencia fluvial a través de la descarga del río Atrato y otros tributarios secundarios.
