Recent hydrometeorological extreme events have highlighted the increased exposure and vulnerability of societies and the need to strengthen the knowledge-base of related policies. Current research is focused on improving forecasting, prediction and early warning capabilities in order to improve the assessment of vulnerability and risks linked to extreme climatic events.
Hydrometeorological Hazards: Interfacing Science and Policy is the first volume of a series which will gather scientific and policy-related knowledge related to climate-related extreme events. Invited authors are internationally recognized experts in their respective fields. This volume reflects the most recent advances in science and policy within this field and takes a multidisciplinary approach. The book provides the reader with a state-of-the art account on flash floods, droughts, storms, and a comprehensive discussion focused on the cost of natural hazards, resilience and adaptation.
Hydrometeorological Hazards: Interfacing Science and Policy will be an invaluable reference for advanced undergraduates taking courses with a focus on natural hazards including climate-related extreme events. The book will also be of interest to postgraduates, researchers and policy makers in this field looking for an overview of the subject.
