Following on from Volume I, this second volume presents an extended look at environmental modelling research and its applications from an even larger selection of global experts. The book presents timely topics and applications of the study of environmental contaminants, with detailed discussions of mathematical concepts used. Five sections cover decision support and assessment modelling; aquatic modelling and uncertainty; soil, sediment and subsurface modelling and pollutant transport; forest ecosystem and footprint modelling; and, air quality modelling and sensitivity analysis. With a section containing figures in full colour, this volume showcases models that predict and simulate the dynamics of environmental systems and are routinely used in environmental decision-making and management. Volumes I and II are essential reading for academics, policymakers, regulatory agencies, technicians, health professionals, engineers, and advanced undergraduate and graduate students involved in all aspects of environmental modelling.
