'This book was worth the wait! What started as a description of a pioneer modelling effort thirty years ago ended up as a comprehensive treatise on soil and landscape evolution enriched by the experience of Dr Willgoose. Hydrologists and geomorphologists interested in a quantitative understanding of what goes on the critical surface zone of the geosphere must read this book.' Rafael L. Bras, Georgia Institute of Technology 'If it moves, model it! There is no better synthesis of all the various elements in landscapes and soil than this lifetime compilation in which Willgoose examines the many mechanisms operating in the landscape, at scales from continental tectonics down to the soil profile, demonstrating how he and others have built them into functional, mutually consistent and inter-connecting models. Its greatest strengths lie in the incorporation of soil processes - physical breakdown, mixing and weathering; and in how principles and models have been applied to the management of degrading spoil heaps.' Mike Kirkby, University of Leeds 'An outstanding synthesis that thoroughly addresses both the theoretical basis and practical application of landscape evolution modelling - a benchmark of its kind.' Stuart Lane, Universite de Lausanne
