This award will support the analysis of the interaction of              infragravity-band wave motions (periods 20-200 seconds) and                     barred topography.  Data were obtained during a nearshore ocean                 field experiment (called SUPERDUCK) in Duck, North Carolina,                    during the fall of 1986.  Theoretical models suggest the                        importance of these motions in sand bar generation, as well as                  the potential tuning of infragravity waves by a pre-existing bar.               The SUPERDUCK data set is unique in its frequent and thorough                   sampling of the three-dimensional bathymetry and the local                      incident (4-20 second) and infragravity wave fields.  Three                     questions will be addressed:  1.  Are there systematic                          differences between infragravity waves and barred beaches and                   those measured over simpler topographies?  2.  If there are                     differences, what are the dynamical reasons for them?, and,  3.                 Are infragravity waves responsible for sand bar generation and                  evolution?
