Abstract : This physical model study of absorbing and reflecting jetties at coastal inlets was conducted to provide data sets that would aid in the calibration and verification of numerical wave models. The study was performed in the Coastal Inlet Research Program's (CIRP) idealized inlet experimental basin at the U.S. Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL), Vicksburg, MS. Safe navigation, sediment transport into navigation channels, and shoreline erosion are all concerns at coastal inlets and are related to the transformation of waves as they change direction and height due to complex bathymetry and coastal inlet structures. The idealized inlet physical model, created for inlet studies, provided a facility in which to make wave measurements of height and direction and the associated wave-generated currents in enough detail to document the wave height and current variation in a region with complex interactions. Measurements of wave information included use of wave rods for wave height and acoustic Doppler velocity sensors for wave direction and current. Qualitative dye photographs and videos were also obtained.
