In the last decades IH Cantabria has dedicated an important amount of resources to developing its own next-generation numerical tools to study offshore wave transformation processes  and their effect on port infrastructures. By using these models developed internally , was added to a specific methodology for the analysis and design of coastal infrastructure based on the integration of the different tools and techniques existing study , to get maximum benefit in the identification of variables associated with the functionality and stability of infrastructure design, culminating in an optimal design and quality.

Amongst the numerical models developed by IH Cantabria we can find deep sea to shorelines wave propagation models such as MOPLA or IH-BOUSS. The latter is a nonlinear wave propagation model which uses Boussinesq equations and allows the study of the nonlinear transformation of waves off the coast for entire sea states. MSP and MANOLO models allow studying port resonance phenomena, both in its phase  integrated version (MSP) as well as in transitional phases (MANOLO) IH Cantabria  offers an extense range of Computational Fluid Dynamics models based on RANS equations both in two-dimensional  (IH-2VOF) and three dimensional versions (IH-3VOF e IH-FOAM), which allow the determination of the fotces that the wave exert on conventional and non-conventional structures, and the study of the variables related with the functionality of these structures, such as overtopping.

Durante la última década, el IH Cantabria ha desarrollado una serie de metodologías pioneras para generar bases de datos históricas Océano-Meteorológicas, tanto a escala global como a escalas regionales y locales. En concreto, para las costas españolas, se cuenta con la reconstrucción histórica de series horarias de viento de alta resolución, oleaje propagado, onda larga, nivel del mar y corrientes de más de 60 años de datos homogéneos, validados y/o calibrados con información instrumental.

Además también se dispone de proyecciones de clima marítimo realizadas con distintos escenarios de cambio climático hasta el año 2100. Efectivamente, IH Cantabria lleva años trabajando en el desarrollo de metodologías que permitan analizar y evaluar los efectos del cambio climático en las zonas costeras. Desde que en 2003 la Oficina Española de Cambio Climático encargara a IH el estudio del cambio climático en la costa, han sido numerosos los proyectos que se han ido sucediendo al respecto, permitiéndo adquirir una amplia experiencia y pericia en este campo.

Los asentamientos urbanos y su desarrollo en las zonas costeras han dado lugar a construcciones que hoy en día se ven afectadas por los impactos del cambio climático. Puertos comerciales, deportivos o pesqueros, vías de comunicación o frentes marítimos sufren los efectos de un clima cambiante. Esto hace necesaria la introducción del estudio del cambio climático en cada proyecto de puertos e infraestructuras. IH Cantabria proporciona, por tanto, una solución integral al diseño de infraestructuras marítimas.

In the last decade, IH Cantabria has been actively involved in the formulation of innovative solutions, development of numerical tools and deep understanding of the physical ocean, to optimize the construction and operation in ports, with the primary aim of adjusting costs, maximize safety of the workforce, and expand efficient working windows. Port activity worldwide has the need to increase the future movement of goods, tackle ever larger ships, expand the discharge areas and maneuver, and implement better and more secure computers. This makes port works projecting increasingly large in size, to move toward outer coastal areas, and therefore exposure to the action is complex, variable, and severe environmental conditions.

This means that there is a rethink in the way of planning the construction process of new port infrastructure, and traditional management in the daily operation of existing infrastructure. Therefore, the builder / manager must understand and manage port processes increasingly complex and costly, in relation to the movement of materials and machinery management on site and must prioritize in setting thresholds for optimal safety staff and labor. Thus, the IH Cantabria at the service manager / constructor port an operational methodology, adapted for the daily management of activities related to the work and operation of seaports, through innovative design tools and algorithms to solve and optimize manage from a predictive standpoint, the various problems inherent in this branch of engineering.

IH Cantabria has a vast amount of knowledge in the field of statistical analysis of environmental variables for many different types of studies: risk analysis; infrastructure life-cycle including pre-design, design, feasability, repairs and maintenance; or climate change. IH Cantabria is able to provide the research and technical background necessary to face many of the new challenges arising in this field.   This is especially true when looking at the continually increasing amount of information available on the variables affecting the marine and coastal environment, both instrumental data from buoys, meteorological stations, cameras, satellites, etc as wella s numerical reanalysis data which require special methodologies and allow including all the available information.

To this effect, IH Cantabria has participated in many different projects involving the statistical characterization of of environmental variables and the analysisi of their variability to be applied to differents fields:

  1. energetic exploitation of coastal resources and their optimization,
  2. climatic characterization of the marine physical environment,
  3. prevention and response modelling for spills in port, coastal and transitional waters,
  4. short, mid and longterm morphodynamic beach evolution,
  5. climate change effects on the coast,
  6. design of coastal infrastructures and wave interaction studies.

The generation of databases on marine variables is the basis for the analysis of climate dynamics and climate change. At IH Cantabria each database generation involves a methodological process that includes, in addition to the numerical simulation of the target variable, the validation of the simulations using instrumental measurements, calibration of the databases and characterization of the simulated climate.

That is why our wave, sea level and wind data bases have three important characteristics: quality, availability close to shore and the length of the available time series,  fundamental to the study of historical changes observed or of future climate evolution.

IH is also developing new techniques to generate databases for future climate projections with sufficient spatial resolution for regional analysis.

One of the key aspects to assessing meteorological oceanographic dynamics is to provide a simplified representation, often using probabilistic parameters and distribution functions of environmental variables.

Researchers in this group have developed, over the last 10 years, various methodologies for the univariate and multivariate definition of marine climate, under either average or extreme regime persistencies (IDF curves). As a result of this research, two recently presented doctoral theses have studied the representation of the maritime climate with data mining techniques and modeling of non-stationary wave extremes, wind, precipitation and sea level.

 

What will the waves and sea level be like tomorrow? What beach area will  be more appropriate for the kids to swim at tomorrow afternoon? Will the oil spill reach the coast in the next few days? Will the tsunam generated  two hours ago in Alaska affect my city? Can I catch quality waves on the beach this afternoon? What is the probability that the port can operate within within the next three days? To answer these questions as best as possible, IH Cantabria has developed various methodologies and numerical and statistical tools for application in operational oceanography, techniques such as nesting and coupling models, refining techniques (downscaling) both dynamic and statistical modeling waves , and current levels associated with different dynamics (storms, tsunamis, density and salinity gradients) and respond to issues related to predicting very short (a few hours), short (24-72 hours) and medium term (15 days) wave, flood, erosion, transport of substances, transportation of hydrocarbons, surf quality, operability port, maritime construction works, impact of tsunamis, ...

Numerical modeling of wind effects in the interaction of waves with structures (Moviola).

The MOVIOLA project, currently underway, will be developed between 2012-2014 and is funded by the Spanish National Reseach Plan (DO).

The goal of this research project is to improve our knowledge and predictive capabilities related with the interaction of waves with the wind in the vicinity of coastal structures. This project stems from research lines opened during the project
MOTIOM (BIA2008 - 05462) in which we studied the three-dimensional processes developed by waves on coastal structures, focusing the analysis on rubble mound breakwaters and on wave overtopping.

Traditional analysis of the effect of wind has been simulated correctly in experimental trials in which the scaling of physical models limits the universality of the results, or from field measurements with a high spatial variability and lack of control of external variables . Although the number of jobs is not very high and has not materialized in any predictive tool as semi- empirical formulation and generally reliable , the effect of wind on the overshoot is well known , acting on the wave waves way peraltando additional and increasing rates exceeded .


The project focuses mainly on improving the modeling of the rupture with and without wind, fundamental aspect rebase to what is considered the presence of air and its effect on the wave, and improvements in the conditions of absorption waves to generate more realistic situations to improve predictive techniques . The proposed methodology intends to use three-dimensional numerical modeling of the Navier -Stokes and physical experimentation centered on vertical breakwaters exceeded . For the numerical study will be used
IH3-VOFmodel , developed within the MOTIOM project which will introduce the physics of air and which expands the range of physical processes used to study the process of wave interaction with coastal structures . The numerical results will be validated by means of experimental test campaigns designed specifically for this purpose in the CCOB, Cantabria Coastal and Ocean Basin,  equipped with a wind wave generation system. The project results will be used to improve and optimize the functional design and stability of coastal structures, reducing uncertainties caused by the wind effects on the determination of theovertopping and effort rates, whic is currently very difficult to determine, and generating a tool for quantification.
