In recent years, increasing ship-sizes and associated increasing wave loads have led to a demand for prediction tools quantifying the ship-induced loads on waterways. Depth-averaged numerical models, using a free surface pressure term, are a prominent method to obtain the relevant design parameters. These models incorporate the wave deformation processes due to attributes of complex bathymetries, while allowing for an efficient simulation of large computational domains. The non-hydrostatic shallow water equations model REEF3D::SFLOW uses a quadratic pressure approximation and high-order discretisation schemes. This paper presents the implementation of a pressure term to account for the displacement of the free surface by solid moving objects. Two test cases verifying the implementation are shown based upon the analytical 1-dimensional solution of the wave propagation due to surface pressure and the estimation of Havelock angles. These verification tests are the first step towards a holistic model, combining a large scale model with CFD simulations near waterway banks.
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
