WWECO - Environmental Assessment and Modeling of Wastewater Discharges using Autonomous Underwater Vehicles Bio-optical Observations (2008-2011)

The main goal of the WWECO project was the development of methods to improve environmental impact assessment and modelling capabilities. Measurements of the spectral optical properties of effluent plumes obtained with the MARES AUV provided detailed maps of effluent dispersion and spatial distribution of resuspended sediments and corrected estimates of plume dilution, providing accurate data for evaluating plume models. These technological developments improve an adaptive sampling approach for the AUV based on the optical data collected in real time, enabling even more reliable measurements of the plume behaviour and its interaction with other coastal physical, chemical and biological processes. An automatic data processing system was developed to enable quicker response in case of contamination risk to near-by beaches..
