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.
Chapter 6: Geomorphology and Society
Geomorphology and Society
Humans evolved in the context of geomorphic processes, and their survival and prosperity depended in no small measure on their understanding of these processes, the threats posed to their survival and implications for food production. Human settlements are often vulnerable to geomorphic hazards by virtue of their location in the path of geomorphic processes such as flooding, landslides or debris flows. In the next level of interaction, human settlement alters geomorphic processes, such as exacerbating the severity of flooding by reducing infiltration and increasing stormwater runoff (for a given unit of precipitation), increasing erosion and sediment yields through land clearance, triggering mass movements by altering drainage patterns or undercutting the toes of slopes and inducing seismic activity through ...
