WebLittoral drift, the wave-driven longshore transport of sediment, plays a major role in shoreline dynamics. Human-induced modification of littoral drift is a ubiquitous cause of coastal erosion (see Human causes of coastal erosion ). Measuring littoral drift in field situations is notoriously difficult and generally subject to great uncertainty.
