Wave penetration, harbour oscillations and downtime
Offshore cables and pipelines
Hydrodynamics and morphology concerns the movement of liquids and the associated changes in soil and landscape. We simulate water levels, wave action, currents and sediment transport patterns to develop optimal design solutions for dynamic environments.
We supply design preconditions for hydraulic engineering structures, analyse the operational availability of ports, and design measures to prevent undesired erosion and sedimentation. We use specialised tools to study morphological changes, shipping incidents and extreme hydraulic loads to optimise the asset management of cables and pipelines on the seabed. We develop in-house tools to analyse processes such as wave penetration in ports (WIHA model), and are involved in research programmes and collaborations with universities.
Witteveen+Bos applies state-of-the-art computer models, at spatial scales ranging from global (parts of oceans) to highly local and detailed (ports and lock complexes). With one of these complex models we can, for example, calculate primary ship waves (the combination of water level drop next to the ship, followed by the stern wave behind the ship). For instance, the model (XBeach) can show how a passing ship can cause a large wave, with an effect on the beach. The size of such a wave depends on more than just the speed. The load displacement of the ship, the distance to the beach and the bed elevation also have an influence.
One of the tools we developed in-house is WIHA (Wave Impact on Harbours). This is a phase-resolving numerical wave model that allows for fast and accurate computation of wave conditions in and around harbours and coastal zones. Its ease of use and short simulation times allow for WIHA to be used in the early phases of design or tender phase of engineering projects. Phases in which a project can benefit most of the insights in the interaction between (hard) structures and waves. Moreover, the model enables to make a fast amount of calculations with high accuracy during detailed design phases. Our specialists interpret these results for optimizations of harbour or breakwater layouts. Furthermore WIHA allows for deriving extensive datasets of wave conditions that can be used for e.g., harbour optimization, DMA studies or the assessment of flood safety.
