Erosion of the coasts during strong storms on the coastal front of the Gulf of Chania, is intensifying in recent years, while infrastructure of major cultural importance such as the Venetian harbour is severely malfunctioning and experiences widespread flooding. Overtopping of coastal infrastructure and consequent flooding are expected to intensify in the near future due to rising sea levels as a result of climate change. It is therefore important to better understand the underlying natural processes that contribute to the wave overtopping of coastal infrastructure. To study any coastal natural processes, knowledge of the wave regime that characterizes an area is essential. Part of the present study concerns the long-term monitoring and analysis of the wave regime in the Gulf of Chania, for the first time. In addition to analyzing the data to describe the wave regime, they were used in combination with wave measurements within the Venetian harbour to study harbor resonance during storm events. Details of thw harbour’s resonance were investigated through numerical simulations. The simulation results were used together with well established wave overtopping equations and a novel methodology was developed to quantify the contribution of resonance to to wave overtopping rates along the harbour’s dock.
