چکیده
Most anthropogenic pollution can be controlled, such as domestic and industrial releases, loads from agriculture, etc. However, some of them, which are associated to illegal discharges, accidents, etc., more difficult forecast. This study was performed on the Tereos sugar industry accident that occurred during night 9 April 2020, when 88,000 cubic meters effluents loaded with organic matter discharged in Scheldt River (a 350 km long transnational river flows through Northern France Western Belgium). The had dramatic consequences receiving watercourse, over 120 downstream. Fish mortalities have been observed severe deoxygenation, reaching zero concentration dissolved oxygen, impacted chemical quality. objective understand describe dynamics its propagation along transboundary hydrographic network Scheldt. A method based processes degradation ecosystem enhanced. It is demonstrated doubtless cause water column deoxygenation. paper shows how quality modelling help therefore prevent accidental a network.
