AbstractIncreased severity of damage to estuarine rock structures have been observed across the major German estuaries during the past two decades. These damages are predominantly caused by long-period primary ship waves, which can result in load cases that are particularly erosive to the rock armour layer. To date no design methods exists to dimension structures for long-period ship wave loads. This study presents an innovative groyne design optimized for resistance to ship-induced waves. During a field trial data were collected which allow for the characterisation of wave-structure-interaction as well as loads and damage parameters for the future development of validated design methods.
