Satellite remote sensing may support the monitoring of water quality during dredging activities for the installation of new off-shore infrastructures.

The use of traditional monitoring techniques (sampling at sea, measures, laboratory analysis) are certainly effective, but they presents logistical and operational inconveniences and long processing times, often incompatible with the need to obtain in real-time the information collected. Furthermore, field observations and measurement, although frequent, are not able to provide a complete and exhaustive spatial answer to describe all the phenomena in progress.

It integrates traditional methods with daily collections of high-resolution satellite images over the area of interest. All the monitoring phases are accurately planned: the programming of the satellite acquisitions, the data collection, the ingestion and processing. Within a few hours this method provides accurate and validated information, useful for the quantitative and spatial definition of the entity the phenomenon of dispersion of sediments during dredging operations.
