Overview

Natural disasters are occasional intense events that disturb Earth's surface, but their impact can be felt long after. Hazard events such as earthquakes, volcanos, drought, and storms can trigger a catastrophic reshaping of the landscape through the erosion, transport, and deposition of different kinds of materials. Geomorphology and Natural Hazards: Understanding Landscape Change for Disaster Mitigation is a graduate level textbook that explores the natural hazards resulting from landscape change and shows how an Earth science perspective can inform hazard mitigation and disaster impact reduction. Volume highlights include: Definitions of hazards, risks, and disasters Impact of different natural hazards on Earth surface processes Geomorphologic insights for hazard assessment and risk mitigation Models for predicting natural hazards How human activities have altered 'natural' hazards Complementarity of geomorphology and engineering to manage threats

Author Information

Tim Davies is Professor in the School of Earth and Environment at University of Canterbury, New Zealand. Educated in Civil Engineering in UK in the 1970s, he taught in Agricultural Engineering and subsequently Natural Resources Engineering at Lincoln University, New Zealand before transferring to University of Canterbury in the present millennium to teach into Engineering Geology and Disaster Risk and Resilience. He has published a total of over 140 papers on a range of pure and applied geomorphology topics including river mechanics and management, debris-flow hazards and management, landslides, earthquakes and fault mechanics, rock mechanics and alluvial fans; natural hazard and disaster risk and resilience. Oliver Korup is Professor in the Institute of Environmental Sciences and Geography and the Institute of Geosciences, University of Potsdam, Germany. Following an academic training in Germany and New Zealand, his research and teaching is now at the interface between geomorphology, natural hazards, and data science. He has worked on catastrophic erosion and disturbances in mountain belts, particularly on landslides, natural dams, river-channel changes, and glacial lake outburst floods. John J. Clague is Emeritus Professor at Simon Fraser University. He was educated at Occidental College, the University of California Berkeley, and the University of British Columbia. He worked as a Research Scientist with the Geological Survey of Canada from 1975 until 1998, and in Department of Earth Sciences at Simon Fraser University from 1998 until 2016. Clague is a Quaternary geologist with research specializations in glacial geology, geomorphology, natural hazards, and climate change, and has authored over 200 papers on these topics. He is a Fellow of the Royal Society of Canada and an Officer of the Order of Canada.
