Advances in Environmental Modelling: Symposium Proceedings(Developments in Environmental Modelling)

This book contains a collection of papers presented at ISEM's 6th International Conference, providing state-of-the-art information on environmental modelling. Particular emphasis is placed on large-scale transport, and the related impact on marine environments, wetlands, lakes and lagoons. The most significant phenomena to play a role in the water quality of such environments are reviewed. In addition, optimal modelling strategies, with particular attention to large water bodies, are suggested. The book should also help to bridge the gap between ecological modelling, on the one hand, and decision makers, on the other, as it contains a special section focussing on modelling the decision-making process and the relationship with public policies.
