The Basics of Geomorphology

Ken Gregory obtained his BSc, PhD and DSc from the University of London, was made CBE in 2007 for services to geography and higher education, and is currently President of the British Society for Geomorphology. Research interests include river channel change and management, palaeohydrology and the development of physical geography, and he has written more than 140 papers, authored and edited 30 books including The Earth's Land Surface (2010) and The SAGE Handbook of Geomorphology (2011). He has 3 Honorary degrees, and received the Founder's Medal of the Royal Geographical Society (1993), the Linton award of the BGRG (1999), and the Geographical medal of the Royal Scottish Geographical Society (2000). John Lewin graduated with a BA and PhD from the University of Southampton. He was Professor of Physical Geography at Aberystwyth University, where he also served as Dean of the Science Faculty and Pro-Vice-Chancellor. His major research interest lies in fluvial geomorphology, especially floodplains, and the development of landforms over a full range of timescales. He is a former chairman of the British Society for Geomorphology and received the Society's Linton Award in 2011.

Although there are many introductory geomorphology books, this latest contribution from Professors Gregory and Lewin is an excellent addition to the genre. They ask fundamental questions on the nature of scientific enquiry in geomorphology, on the burgeoning field of complexity studies and its interface with traditional geomorphological questions, and on the ways in which geomorphic processes relate to real world problems. The chapter on the Anthropocene illustrates well the variety of perspectives that geomorphologists have on this latest theme in geomorphology. The book is replete with boxes, web sites and recommendations for further reading. I would have appreciated having a copy of this book when I taught the introductory and follow-up geomorphology courses. -- Olav Slaymaker As Geomorphology has matured as a discipline, so it has developed a range of concepts which are fundamental for understanding it. This book, written by two leading geomorphologists, provides a very welcome first attempt to explain the major concepts in a concise and accessible way. -- Andrew Goudie, Emeritus Professor of Geography Geomorphology and Earth sciences in general have been profoundly transformed by ideas that expand our vision from "normal" or "equilibrium" forms and developmental pathways (with exceptions to the pattern treated as deviations) to a much richer vision. The latter recognizes multiple possible pathways and outcomes, and landscapes and landforms that encompass, but transcend, classical equilibrium notions. Basics of Geomorphology is to my knowledge the first and only geography or geology textbook that fully embraces this new vision. Gregory and Lewin have managed the difficult but important task of distilling a new set of "basics" from these revolutionary insights that both broadens and complements traditional ideas. This book is remarkable in the way that it acknowledges a wonderful plurality of conceptual frameworks and approaches, and explains them in a clear, engaging way. Time will tell, but this book may well mark a turning point in the way students and scientists alike perceive Earth surface processes and landforms. -- Jonathan Phillips This book provides a very accessible overview of the discipline of geomorphology that is well supported by web-based material. The text is up-to-date, with excellent reference to relevant literature, and presents the discipline in an interesting and novel way. It provides a very readable and informative introduction to the discipline for senior undergraduates, postgraduates and researchers approaching the subject from other areas of science. -- Angela Gurnell In the current millennium humans have reached a critical point for coping with the surface of their planet, including its changing climate and environments, the alarming vulnerability to its hazards, and the increasingly complex problems of sustainability. All of these interrelated concerns require renewed attention to geomorphology, the science that deals with Earth's land surface and the processes that operate thereupon. I can think of no better guides than Professors Ken Gregory and John Lewin to lead the reader through the conceptual basis of this exciting science, as they do in their new book: The Basics of Geomorphology: Key Concepts. I highly recommend this book to those wishing for an up-to-date introductory overview of this rapidly changing science that is so critical to preserving the continuing habitability of our planet. -- Victor R. Baker 'Geomorphologists often struggle to understand and see the relevance of philosophy. This book provides an ideal introduction to geomorphological concepts packaged in a user-friendly and non-threatening way'. -- Heather Viles At a time when Earth's surface is changing rapidly, a geomorphology text centering on systems concepts, including interactions and adjustments, is especially timely. While grounded in key concepts of the discipline, this text prepares students for confronting new challenges ahead, including increasing human interactions in the "Anthropocene." -- Anne Chin Understanding geomorphologic concepts has become more important in recent years given the increase in various environmental issues. Gregory (president, British Society for Geomorphology) and Lewin (formerly, Aberystwyth University) have written a useful, moderate-sized textbook on the subject supported by an extensive companion website. The website contains PDF files of each chapter,including tables and diagrams, chapter synopses, and citations from Progress in Physical Geography that are not available in the book. The site also contains an extensive list of references (50-plus-pages)and a glossary. This very readable book and the easily accessible website greatly facilitate learning and understanding of this important topic in geology. -- M. S. Field, U.S. Environmental Protection Agency Its focus is the core principles of geomorphology. It is an impressive survey of the philosophy and historiography of the discipline, with dense and readable introductions to topics as diverse as cycles, landforms, uniformitarianism, the Anthropocene, and geomorphic hazards... This thought-provoking book is an anchor for serious students who are seeking those skills, afloat in the internet age. -- Chris Pyle, Lancaster Royal Grammar School
