The complex interaction of surface waves with coastal inlet structures and inlet morphology is of significant importance to navigation channel operation and maintenance. Wave data in the vicinity of coastal inlets are limited. Where field wave data exist, the temporal and spatial coverage is inadequate to resolve the evolution of wave refraction and diffraction patterns of the free surface. To address the challenge of quantifying variations in wave direction in the coastal system, the US Army Engineer Research and Development Center applied video techniques in a physical model to obtain spatially and temporally dense measurements of wave direction. These measures are required to advance understanding of first-order inlet processes and to use the measurements in numerical simulation model development and verification. In this paper, detailed results are discussed for random and a single monochromatic wave experiments conducted for evaluation of wave diffraction patterns influenced by coastal structures and coastal inlet bathymetry.
