MARHIS (Maritime Aggregated Research Hydraulic Infrastructures ) is a distributed ICTS that aims to improve Spanish competitiveness and efficiency in the field of maritime hydraulic engineering. It aims to increase the efficiency and capability of Spanish numerical, experimental and field facilities for applications to coastal, harbour and offshore engineering. The facilities that forms part of this distributed ICTS are managed by the Maritime Engineering Laboratory that belongs to Universidad Politécnica de Cataluña, El Pardo Hydrodynamics Experimentation Centre that belongs to INTA, PLOCAN Consortium and Biscay Marime Energy Platform (BIMEP).
The GTIM-CCOB, located in the PCTCAN is managed by the Foundation for Environmental Hydraulics Institute. Its facilities are equipped with the latest technology for creation of waves, currents, and wind, with capacity for physical model testing. Here, phenomena are studied related to the generation and propagation of waves, wave-wave interaction and waves-structure interaction, stability and behaviour of coastal protection structures, seawalls and maritime structures, behaviour of floating structures, the operation of valves and hydraulic machinery, as well as the testing of devices for the generation of marine energy. It enables physical and numerical modelling of problems in deep and shallow waters, as it has the capacity for testing at any range of depth, including the possibility of carrying out experiments at depths equivalent to 1,000 m at a scale of 1/100. It features two flumes for directional waves with the capacity to generate currents and wind, three flames for waves-currents, one current flume with a variable slope, a tank for the study of hypersaline spills, along with an area for the construction of fluvial models. The GTIM-CCOB tank has a width of 44 m, a length of 30 m, and a variable depth (maximum of 3.4 m), the capacity to generate multi-directional waves, omni-directional currents and wind, as well as a trench of 6m in diameter and 8 additional meters of depth. It is also worth noting the waves-currents-tsunami flume named COCoTsu (56m in length, 2 m in width, and variable height with a maximum of 2.5m), due to being an innovative facility designed for medium and large-scale testing of structures for coastal protection, floating structures, studies of wave-current and wave-structure interaction, among others.
