Geomorphology is the study of the Earth's diverse physical land surface features and the dynamic processes that shape these features. Examining natural and anthropogenic processes, The SAGE Handbook of Geomorphology is a comprehensive exposition of the fundamentals of geomorphology that examines form, process, and history in the discipline. Organized into four sections, the Handbook is an overview of foundations and relevance, including the nature and scope of geomorphology, the origins and development of geomorphology, the role and character of theory in geomorphology, the significance of models and abstractions to geomorphology; techniques and approaches, including geomorphological mapping, field observations and experimental design, remote sensing in geomorphology, quantifying rates of erosion, measuring fluid flows and sediment fluxes, dating surfaces and sediment, GIS in geomorphology, and modelling landforms and processes; process and environment, including rock weathering, the evolution of regolith, hill slopes, riverine environments, glacial environments, periglacial environments, coastal environments, desert environments, karst landscapes, environmental change and anthropogenic activity; and environmental change, including geomorphology and environmental management, geomorphology and society, and planetary geomorphology.

Remote Sensing in Geomorphology
Remote sensing in geomorphology

Remote sensing techniques have evolved considerably since the days of aerial photography and color–infrared film. Imaging spectrometers produce images in over 200 spectral bands, thermal infrared sensors pick up temperature and emissivity variations, and imaging radars map surfaces in multiple wavelengths and polarizations (Lillesand et al., 2008). High-resolution sensors provide images from space at better than 1 m resolution of nearly anywhere on the planet. At the same time, new techniques for measuring the third dimension, topography, at moderate-to-high resolution have been developed: lidar or laser ranging, and interferometric imaging radars have joined the time-honored technique of stereophotogrammetry to provide geomorphologists with unprecedented accuracy and coverage.

The development of these techniques has coincided with a vast improvement in ...
