DESCRIPTION:Predicting beach shoreline changes remains a challenge given t
 he complexity of the processes affecting sediment transport at a wide rang
 e of temporal and spatial scales. Here\, two different approaches are take
 n to improve our understanding of sandy beach shoreline changes: (1) a dat
 a-based approach with the development of an empirical shoreline change mod
 el based on equilibrium beach profile concepts\, and (2) a physical modeli
 ng approach by measuring the profile changes during storms in a series of 
 wave flume experiments. The equilibrium model was developed with data from
  Torrey Pines\nBeach\, CA\, USA and has been applied at several different 
 sites\, including a macrotidal site where the effects of changing water le
 vels are taken into account. In the second part of the talk\, results from
  a series of wave flume experiments are presented to show the efficiency o
 f submerged structures in reducing coastal shoreline erosion\, based on an
  equilibrium profile approach.
