AB Characterization and monitoring of river plumes according to their main drivers (river discharge, wind and tide) is important to determine their impact on the adjacent coastal zone. The river discharge changes the thermohaline properties, causes changes in the currents circulation and transports suspended organic matter to coastal ocean water modifying its biogeochemical properties. Under certain circumstances: heavy rains and certain winds in platform, river inputs can penetrate into the nearby estuaries. Current technology allows plume satellite tracking (MODIS) through the analysis of the radiance. This technology has a resolution of up to 250 m, allowing to identify and characterize the river plumes, not only on the continental shelf, but also its possible intrusion into the outer and middle area and adjacent estuaries. This methodology will be used to characterize the Minho River plume and its possible intrusion into the Galician Rías Baixas. Synoptic river discharge, wind and tide conditions favourable to plume intrusion on the Rías will be characterized. After its correct identification, which is based on satellite data that covers only the near-surface meters, it is intended to complement the characterization with plume hydrodynamic simulation in the water column by numerical modelling.
