Description :
Recent technological developments in the application of the Global Positioning System (GPS) offer the prospect of rapidly mapping difficult terrain and quantifying temporal and spatial dynamics of erosion and sedimentation. In the uplands of Northern England, 3 case studies demonstrate the trade-off between the advantage of speed and disadvantage of reduced accuracy afforded by GPS. The studies are concerned with the rapid mapping of flood extent based on ephemeral flow limit indicators; detailed mapping of alluvial fan surfaces and associated sediment sources; and the spatial distribution of colluvial sediment supply and downstream movement of bedload slugs.
