This paper provides data on weathering properties and reduction factors for two geotextiles in ocean environments. The study included outdoor ultraviolet (UV) exposure tests performed at the Harbor and Marine Technology Research Center in Taiwan using a black polypropylene and a white polyester geotextile. Ultraviolet exposure was the most significant factor in reducing the strength properties of the geotextiles tested in an ocean environment. Seawater immersion had the least weathering effect on the engineering properties of the test geotextiles among the test conditions. The effect on engineering properties of placing samples within the tidal zone was slightly higher than that for the immersion condition. Reduction factors for UV exposure and seawater weathering for the test geotextiles are reported.

This study uses a numerical method to analyze the proposed model structure. Before the parametric analysis, a pre-analysis to make sure the analytical results are accountable, a verification analysis was performed. The results found are compared well with the limited experimental findings of Goda et al. and it is very encouraging to find that for the proposed method as an alternative for green energy developments, as long as an appropriate design is performed, an OWC combined with breakwater structure may provide an alternative for green energy system utilized in a harbor area. From the results of the first stage of parameter analysis that the size of the openings of the cell of converting system is variable, a traditional full opened cell is not necessary the most efficient design for the wave power conversion in terms of the variations of air pressure inside the cell and air speed through the outlet orifice that will drive the electricity power generator.
