Determinando umbral de interacción entre el río Magdalena y la Ciénaga Grande de Santa Marta

Abstract

The Ciénaga Grande de Santa Marta (CGSM) is a coastal complex in northern Colombia comprising interconnected lagoons, bounded by the Magdalena River (RM) and the Caribbean Sea. It is a system of great ecological, economic and ecosystemic wealth, so it has been declared an area of protection by different international organizations. However, its quality has gradually deteriorated due to multiple factors obstructing the connection channels between the RM and the CGSM. That led to hypersaline lagoons, as the Caribbean makes up for the missing volume. Solutions have focused on opening new channels or expanding existing ones that connect the CGSM with the RM, yet the problems have not stopped. This research calls to guarantee a minimum flow rate and a gradient so that the flow is effectively carried out in the desired direction and not in the opposite direction. That by analyzing the flow series in the lower basin for different contexts, both temporal and ENSO events.
