This book, written by two leading geomorphologists, provides a very welcome first attempt to explain the major concepts in a concise and accessible way.This student focused book provides a detailed description and analysis of the key concepts, ideas, and hypotheses that inform geomorphology. Kenneth Gregory and John Lewin explain the basics of landform science in 20 concepts, each the subject of a substantive, cross-referenced entry. They use the idea of the 'geomorphic system' to organise entries in four sections, with extensive web resources provided for each:System Contexts: The Systems Approach / Uniformitarianism / Landform / Form, Process and Materials / Equilibrium / Complexity and Non Linear Dynamical SystemsSystem Functioning: Cycles and cascades / Force-Resistance / Geomorphic work / Process Form ModelsSystem Adjustments: Timescales / Forcings / Change Trajectories / Inheritance and Sensitivity / AnthropoceneDrivers for the Future: Geomorphic Hazards / Geomorphic Engineering / Design and Prediction
