Transport of sediments along the coast is termed longshore drift. Net longshore drift directions may change due to variations in coastal orientation, forming drift cells. Each drift cell is based on net uni-directional longshore movement of sediments over a long period of time, in spite of any lesser, seasonal, movement in the opposite direction. A drift cell comprises source (z2one of erosion), transport corridor (zone of transport) and sink elements (zone of accumulation). Drift cells may begin and end in broad, poorly defined zones, and may vary from tens of meters to scores of kilometres in length. The systematic use of geomorphic and sedimentological indicators to determine net longshore drift cells along a coastline is a quick and accurate method with which to provide qualitative information to support an initial framework for coastal management decisions. Geomorphic indicators can be easily obtained either from comparison of aerial photographs (best scales and results) or satellite images from different years and seasons. However, because these remote sensing products represent just an instantaneous taking, they must be used with some restriction. Geomorphic indicators of net longshore drift cells comprise: natural and artificial structures interrupting longshore drift causing sediment accumulation against one side of the structure and erosion against other one; spit growth, stream mouth diversions and inlet migrations have the direction of net longshore drift; beach width, which increases in the downdrift direction; plan configurations of deltas and intertidal fans, and beach morphodynamics (including surf zone, longshore bars and beach cusps morphologies, embayments and tombolos) provide important information for determination of narrow or broad shore-drift cells; coastal dunes and bluff morphology and extent, and coastal erosion evidences along beach can also give good information about drift cells; suspend sediment plums and the angle that waves approach the shoreline indicate the direction of longshore current.
