- Experiments using focused wave groups are a convenient way to estimate extreme wave run-up and overtopping, important in the design of coastal defences. This paper quantifies the substantial over-estimation in wave runup and overtopping that occurs when compensation of second-order error waves in these experiments is not undertaken, potentially leading to overly-conservative design of coastal structures. As a result of these findings, existing design approaches will need to be scrutinised to ensure that the lack of second-order error wave corrections have not unduly influenced the outputs of artificial neural networks that underpin design guidance.
