This task has covered environmental models, their importance, and the process of modelling. Different types of models were analysed, and their applicability within different contexts was also discussed. Within the context of the impact of nutrients on coastal waters we paid particular attention to the NEWS-model. 

To finish this task, write a short report in which you use the information gained throughout this task to answer its main questions: 

What is the environmental importance of models for soil-water systems and how can issues surrounding nitrogen deposition be incorporated?
