Abstract

The processes that shape the Earth's surface have a variation or rhythm that can be measured in the field using a number of instruments and techniques. This chapter describes electronic field equipment that has increased our capacity to investigate sediment transport and fluid flows in coastal, fluvial, and aeolian environments. This equipment includes: (1) anemometers, velocimeters, profilers, and hydrophones for Eularian flow measurement; (2) traps, impact sensors, and backscatterance sensors for sediment transport measurement; (3) drogues, particle image velocimeters, and electronic tracers for measuring Lagrangian flow and transport; and (4) erosion pins, distance sensors, and sonar altimeters for measuring bed elevation change. Modern deployment of these instruments and past applications are described with respect to the spatial and temporal scale of the processes being examined, and the methodological and interpretative limitations inherent to field deployments. © 2013 Elsevier Inc.
