Examples of COHERENS applications
Managing oil spills
COHERENS has been coupled to an oil spill model (OSERIT; Dulière et al 2012) to generate simulations of the 3D drift and fate of marine oil pollution in the Southern North Sea. This model tool is accessible 24/7 to Coast Guard Centres through a web-interface and provides scientific-based information to support the decision-making process in case of an oil spill. For instance, it can be used to help plan operational interventions, assess the possible environmental and socio-economic impacts, decide whether chemical dispersants should be used or not or even, identify potential polluters.
This project was funded by BELSPO.

Linking eutrophication problems to human activities
To study the growing anthropogenic pressure in the river watersheds, and subsequent increase in nutrients (nitrogen and phosphorus) loading to the Southern North Sea. COHERENS has been coupled to an ecological model (MIRO; Lancelot et al., 2005) and a generic watershed model based on Riverstrahler/Seneque (Billen et al. 1994). A nutrient tracking approach (Ménesguen et al. 2006) has been adapted and implemented to allow tracking the nutrients in the ocean-river continuum and trace back their sources up to the watersheds. This allows to link eutrophication problems at sea and anthropogenic nutrients inputs but also, for instance, to test nutrient reduction strategies.
This work is being carried out in the framework of the EMoSEM EU project (http://odnature.naturalsciences.be/emosem/) .
