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.

Geomorphology Underground: The Study of Karst and Karst Processes
The central focus of karst research is on understanding karst landforms above and below ground. This requires understanding of the nature and controls of dissolution processes in the comparatively soluble karst rocks and the underground flow systems that may develop as consequences of these processes. Karst studies thus are rock-specific. The principal host rocks are limestone, marble and dolomite (carbonates), and gypsum, anhydrite and salt (evaporites). Individual beds, members or even entire formations of these rocks can be monominerallic or nearly so, with the result that there is little insoluble residuum to obstruct the propagation of initially tiny solution conduits along fractures in them. Pure siliceous ...
