Mission
The Marine Energy and Hydraulic Structures Group is committed to the development of environmentally friendly, sustainable, cost-effective and reliable cutting-edge technologies or solutions to effectively explore water resources and their vast potential, including the harnessing of marine and hydropower renewable energies, as well as to protect key infrastructures, assets and populations from natural hazards and to promote climate change resilience in the long term. Research activities focus on: marine and hydropower renewable energy assessment, development and testing of marine energy conversion technologies, design and testing of bottom-fixed and floating structures, aquaculture and mooring systems, risk assessment and reliability analysis, coastal protection interventions, nature-based solutions, breakwaters and ports design, assessment and mitigation of coastal risks, climate change adaptation pathways, dam engineering, among others. Furthermore, the group aims to provide cutting-edge knowledge and groundbreaking contributions to the design of hydraulic structures in general, including, dams, bridges, scour protections, water supply networks, water drainage systems, offshore structures, coastal structures, among many other examples, by means of both physical and numerical modelling. The group’s research lines aim to be aligned with the EU Green Deal strategy and the UN’s Sustainable Development Goals, as well as to promote the knowledge transfer towards the competitiveness of the stakeholders dealing with Marine Energy and Hydraulic Structures design, operation, maintenance and management.
Expertise
The main research areas are the development, modelling, design and optimization of technologies and solutions towards a vast array of fluvial, coastal and offshore applications. These range from marine renewable energy assessment and conversion to novel green-grey coastal interventions capable of withstanding the harshness of the sea environment in a context of climate change. The group also focus on research towards the multi-use of hydraulic infrastructures, e.g. combined aquaculture with offshore wind, wave and solar energy combined, among other examples. The group yields a vast expertise on optimised design, testing and development of Hydraulic Structures in general, from the fluvial to the offshore environment. This is possible due to the group’s top expertise in both physical modelling, with reduced-scale models tested in cutting-edge experimental facilities (wave basin, wave-current flume), and numerical modelling, via the application of a wide range of hydrodynamic and morpho-dynamic numerical codes (e.g., Delft3D, X-Beach, SWASH, Reef3D, HEC-RAS, PLAXIS 2D and 3D) as well as potential flow codes and advanced CFD models to assess soil-fluid-structure interaction and dynamics (e.g., BIEM, RANS, SPH, Flow 3D). Fluvial and Met-ocean statistical models for multivariate extreme phenomena prediction are also included (R, Python). An integrated approach to the full-water cycle is also in the group’s scope, namely, by concerning research on water quality, water re-use and other engineering and environmental related topics.
Facilities and Equipment
The main activities are conducted within the Hydraulics Laboratory, at the Faculty of Engineering of the University of Porto. The facilities include a current flume with adjustable inclination, with 17 m in length, 40 cm in width and 60 cm in height, which is mainly used for fluid dynamics and sediment transport studies. There is also a 32.3 x 1.0 x 1.0 m wave-current flume, which is equipped with a wave piston-type paddle enabling the combined flow of waves and currents, to study 2D physical models of coastal structures, sediment transport and offshore foundations under regular and irregular sea-states. For both 2D and 3D models, there is a wave basin, 28 m long, 12 m wide and has a height of 1.2 m, with a central pit that enables to increase the water depth to 2.5 m. It is equipped with a multi-element piston-type wavemaker system capable of reproducing regular waves or irregular sea-states, including multi-directional waves. The wave basin has both active and passive absorption systems to reduce wave reflection. Auxiliary equipment includes resistive-type wave gauges, pressure sensors, a Qualisys motion tracking system, a LDA and ADVs, a 3D laser scanner, load cells and hydraulic pumps, a 3D printer, among others. There are also numerous simplified models, from a miniature wave flume to hydraulic circuits, made available for exposition and lecturing of visitors and/or students.
