Structure Performance and Maintenance
The stability and serviceability (wave overtopping) of hardly-reshaping berm breakwater of Ordu-Giresun International Airport and four alternative cross-sections of fully- and partly-reshaping berm breakwaters are assessed by physical model experiments. The tested model sections have quite long berms (B/HsD = 3.9) above the design water level (hB/HsD = 0.29). Recessions observed in the experiments are slightly less than the computed recessions by Lykke Andersen et al.’s (2014) formulation. The measured overtopping discharges are less than the computed values with an order of magnitude of 10 on average using either Sigurdarson and van der Meer (2012) or Lykke Andersen (2006) formulas.
