Committee on Coastal and Maritime Hydraulics

Maritime Hydraulics covers all aspects of maritime, coastal and estuarine problems including coastal morphology, waves, tides, currents, sedimentation and pollution. The activity of the IAHR Maritime Committee is focused on six topics:

• Study of environmental parameters such as waves, tides and currents through: Field data collection, analytical methods and numerical and physical modelling techniques. Special emphasis is given to achieve a better understanding of non-conventional parameters such as wave groups, bounded short and long waves, wave asymmetries, directional waves, etc. and their relevance to structural response.
• Design of ports & harbours and their optimisation through physical and numerical modelling including design of fixed and floating structures.
• Analysis of bed load and suspended load, cross-shore and longshore currents involved in sedimentation and bed evolution, erosion and deposition problems related to structures, and dredging.
• Study of pollution problems including convection of pollutants by currents, residual drift, dispersion and diffusion.
• Coastal and ecosystem management including the interaction of the coastal environment with coastal developments.
• Study of consequences of sea level trends and impacts on coastal engineering.

Contacts with other organisations, such as the Coastal Engineering Research Council (CERC) of the American Society of Civil Engineers, the Permanent International Association of Navigation Congresses (PIANC), the International Towing Tank Conference (ITTC), are well established.
The present effort is mainly focused on improving numerical and mathematical models of coastal processes through a better understanding of the associated complex physics. As well, there is the need for certain field data to validate these numerical models.
Many laboratories are now equipped with segmented wave generators that can simulate the multidirectional characteristics of natural sea states. Although the use of multidirectional waves provides a more accurate representation of wave interactions with structures, often resulting in more cost-effective and safer designs, there are limitations again in the lack of sufficient field data.
One of the priorities of the IAHR Maritime Hydraulics Committee is to form international Working Groups for standardising and validating analysis algorithms that can be used both in field and laboratory situations.

Remote sensing and exchange of field data: Future fields of investigation will revolve around remote sensing, including the launching of a new generation satellites. The exchange of data and the access to data banks have to be improved.

Interdisciplinary approach of ecology: Especially in the field of numerical tools, there is a need for closer ties between specialists in hydraulics and specialists in ecology; for example between physicists, biologists, chemists and ecologists.

Sea level rise: The expected rise in sea level and associated climate changes will most probably have severe consequences for coastal and estuarine management.
