AbstractIn the frame of the MEGAN Project, an integrating approach is proposed in order to understand the marine ecosystem connections between the Gulf of Cadiz and the Alboran Sea, including those processes controlling the nutrient inputs and the corresponding biological response. Among the main processes, the river discharges to the Gulf of Cadiz are expected to play an important role in contributing to the nutrient supply to this system, as it may be inferred from turbidity images acquired by several satellites. To asses the influence of these discharges a methodology based on the catchment model SWAT have been developed for the Guadalquivir river basin. After the calibration and validation of the model, some numerical experiments are performed under characteristics meteorological patterns of the region, which have been simulated with the MM5 atmospheric model. The results obtained have allowed a first evaluation of the contribution of the river discharges to the nutrient input to the Gulf of Cadiz. Further extension of the methodology to the other relevant river basin discharging to the Gulf of Cadiz and the Alboran Sea, along with the evaluation of the other involved processes, will allow to assess the relative importance of the river discharges to the Gulf of Cadiz in the nutrient supply to the Alboran Sea through the Strait of Gibraltar.
