Operational since 2011
Scientific Description
This RI is an ICTS (Unique Scientific and Technological Infrastructure), included in the Spanish National Roadmap for RIs. The Coastal Engineering , Oceanography and Hydraulics Laboratory (GTIMC) performs physical model testing in which phenomena related to the generation and propagation of waves, wave-wave interaction and wave-structure, stability and behaviour of coastal protection structures, breakwaters and marine structures, behaviour of floating structures, operation of valves and hydraulic machine and device testing marine energy generation are studied. The GTIMC is a directional wave basin which is capable of generating simultaneous currents and wind. In addition to the avobe, the laborotory manages a second (smaller) directional wave basin, 3 wave-stream flumes, 1 flume with a variable slope, 1 tank for the study of hypersaline discharges and a construction area for river models.The capacities of the facilities, the experience of the team members and the use of software-numerical modelling and advanced instrumentation, allows basic research on the behaviour of fluids, structures and devices, calibration and validation of all kinds of numerical models and the testing of specific design and optimization of structures and models used in the fluvial and marine environment.

Model testing

GTIMC personnel have a long experience in testing scale models of coastal defenses, renewable energy devices, ports, mooring systems, hydraulic experimentañl devices, etc. Prototipes generally designed by research centres or particular clients.

Access to Coastal Engineering, Oceanography and Hydraulics Laboratory

GTIMC is open to researchers for R&D activities where waves, currents and wind are the main environmental input. Large scale model tests can be performed in GTIMC facilities.

Wave generator

64 individual wave paddles can generate any kind of directional waves required. Paddle configuration can change for piston type (shallow water tests) or flap type (deep water tests).Wave paddles can generate all kind of waves: monochromatic, random, unidirectional, multidirectional, solitary, spectral, bimodal, et. Wave generator is equiped with active wave absorption.

Bridge crane

A 10 Ton bridge crane allow to place the scale model in place when the scale model is portable and it is externaly manufactured and/or provided by researchers or private clients.

Large-scale wave tank

30 m x 44 m x 4 m (long, wwide, depth) with a practicable center pit of 10 m water depth for offshore models. Wave dissipators are installed in three sides of the tank, while a versatile wave generator can be found in the fourth side.

Sensors and measuring techniques

GTIMC has cutting edge measuring technologies for all physical parameters of interest in wave/current/wind model testing. 3 different technologies for wave measuring, 3 techniques for wind measuring, Qualisys system for 6-DOF floating devices movement, PIV-LIV technologies, HD-HS video technologies, pressure gauges, load cells, etc.

Current generator

Wave tank can simoultaneously produce currents. These currents can be colinear or not to the waves propagation. Current direction and intensity can be modified.

Wind generator

In addition to waves and currents, GTIMC can produce winds in any direction and intensities up to 75 km/h. A portable wind blower device can be placed anywhere along the wave tank.
