This study evaluates how the changing of solid and liquid discharge through the Canal del Dique channels affects the sediment transport pattern in the Barbacoas bay and towards Islas del Rosario. The changes correspond to six alternatives brought up in order to diminish the sediments discharge towards the Cartagena Bay. The study is based on mathematical modeling using the tridimensional method ELCOM after calibration and validation with field measurements of the variables representing the external forcing and variables representing the internal dynamics of the stratified flow characteristic of the bay. The horizontal transport pattern was simulated by following an inert and neutrally buoyant tracer. The sedimentation process was not considered hence, only the horizontal transport is described and the results illustrate a situation more adverse for Islas del Rosario than the actual situation. The results show that the transport pattern is strongly influenced by the wind at the Bay. The tracer reaches Islas del Rosario, in low concentrations and sporadically. There was not a peripheral concentrated current that could produce most of the sediment horizontal transport and the wind direction variability was identified as a key factor to produce transport towards Islas del Rosario. The comparison of the alternatives for changing the liquid and solid discharge though the channels of the Canal del Dique allowed to identify that one which would produce less transport towards the Islas del Rosario.Downloads
