We experimentally demonstrate the existence of water wave band gaps in finite two-dimensional periodic graphitic and triangular structures composed of vertical cylinders which stand on the bottom of the water tank and project out of the water surface. The experimental data agree fairly well with the numerical simulations obtained from the multiple scattering method. The experimental evidence of water wave band gaps suggests that two-dimensional periodic structures of vertically oriented solid cylinders constitute a much better solution for the problem of coastal erosion.

    A regional classification of shoreline segments along the Alaskan Beaufort Sea Coast was developed as the basis for quantifying coastal morphology, lithology, and carbon and mineral sediment fluxes. We delineated 48 mainland segments totaling 1,957 km, as well as 1,334 km of spits and islands....
