Optimized Rock Groyne Design for Long-Periodic Ship Wave Loads

Abstract

Increased 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.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/FnrU8AKBITo
