IH Cantabria has gained broad experience in the areas of marine dynamics, coastal dynamics, management of coastal erosion problems, regeneration projects beach and dune, environmental impact during dredging and the impact of dredging ditches and canals in coastal navigation over its 25 years in the field.
All this experience has allowed IH Cantabria to develop new methods and numerical tools such as Coastal Modelling System (SMC), which produces reliable results for technical studies of coastal related issues such as beach regenerations: Diagnosis, Pre-design (blueprint), design (project) and Monitoring and evaluation of the works, providing environmentally sound solutions which are compatible with the functionality and stability of the proposed alternatives.
IH Cantabria can carry out its service anywher in the worls, with dynamic wave, tidal and meteorological and astronomical rise of sea level databases. These databases are obtained numerically through reanalysis, calibrated and validated with satellite data and instrumental data, while at the same time providing numerical methodologies and tools developed to conduct studies of high quality and precision.

IH Cantabria tiene una larguísima trayectoria en proyectos de estructuras costeras. Bien sea para la defensa de tramos de costa amenazados (en los caso en los que una medida blanda no es posible) como en la protección de ámbitos portuarios, diseño de emisarios submarinos, estructuras de captación de agua, tomas y vertidos de desaladora, etc, IH Cantabria es su instituto de referencia. El conocimiento acumulado de IH Cantabria en el diseño de cientos de estructuras costeras, el empleo de las mejores y más modernas herramientas de trabajo (teórico, numérico y experimental (CCOB)) y la capacidad de enfocar desde la perspectiva de la investigación el diseño de estructuras no convencionales solo se conjuga en IH Cantabria.

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:
- Multidisciplinary Research Consortium on Gradual and Abrupt Climate Changes an their Impacts on the Environment (GRACCIE)

Surf-zone mid-term morphodynamics (2010-2013), is an R&D project financed by the Spanish Ministry of Economy through the Juan de la Cierva programme. Its main goal is to research the impact of morphological changes which take place on the surf zone by developing numerical models and analysing the data obtained through the HORUS video monitoring system. The surf zone is a complex 3D system in which the morphologyresults not only from the exterior forcing or external structures, but also due to its own behaviour, producing rythmic bars and rip currents due to self organization mechanisms. These characteristic surf zone patterns affect the coast line and the width of the dry beach.
The Coastal Modelling System (SMC) is a tool that includes a set of methodologies and numerical models, which allow us to study coastal processes and to assess the variations of a beach due to natural events or human activities on the coast.
Faced with a problem on the coast, this methodology allows us to define who we are to carry out studies, spatial and temporal scales that we analyze, which we apply numerical tools that need input data for our analysis. With the SMC are conducted case studies of coastal engineering projects, allowing the analysis of actions at different stages of a study: diagnosis, pre-design, design and environmental impact.
SMC has been designed to be user friendly and has been adapted to many countries, with a wide range of applications.
SMC consists mainly of four modules:
medium and long term module
The COASTVIEW(2002-2005) is a European project which brings together universities, research centers and institutions who have an interest in coastal management. The project aims to implement a video camera system to monitor the coast. It aims to show the usefulness of these types of systems to effectively manage coastal systems and help understand the morphodynamic processes taking place.
Within this project, IH Cantabria has installed a video system studying the beach of "El Puntal" of Santander. The implementation of this system and a series of field campaigns carried out within the project, provided the basis for the development of numerical models and algorithms that allow the identification of image based indicators, in order to solve problems related with navigation safety in the port access channels, understand and protect the beaches and dunes from potential erosion, flooding, dredging impacts or construction works, and of course the social aspects of a beach such as this one which is heavily used during both summer and winter seasons for many different sporting and tourist activities.
The dynamic line marine research focuses on the study of propagation of waves, currents and sea level from turbulent processes to the processes in the larger spatial and temporal scales.
The projects carriedout in beach morphodynamics have contributed to major scientific breakthroughs, simulating both the morphology of the beaches in the short term by means of beach plan evolution (2DH) and profile (2DV) models, as well as in the understanding of the processes in the long term, through the development of beach specific models which take into consideration seasonal variability in beaches.
IH Cantabria invests heavily in knowledge transfer of scientific results to ensure that they benefit society, implementing models and working methods which are the result of research and experience and making them more user friendly. An example of this type of tool is the Coastal Modelling System SMC. The models developed adhere to a continuous process of validation and callibration using experimental testing in our lab facilities IHLabHidro and field testing through our beach monitoring systems.
