Responding to an increase in the intensity of natural and anthropogenic stressors, this book reviews the various approaches to the integrated modeling of climate and hydrology and provides practitioners with a useful framework for environmental assessment. This book looks at understanding interactions and relationships between environmental components, such as climate, land, hydro, ecology, and resulting responses due to stressors in cumulative effects assessment, reviews modelling approaches and existing integrated modelling systems, and proposes an integrated modelling framework and perspectives for future research.
