TESEO is a numerical model to simulate the transport and weathering of oil spills in the marine environment as well as trajectories of floating objects and person in water. The model has been developed by IHCantabria in the framework of different projects, as ESEOO project (2004-2006), funded by the Spanish Ministry of Science and Technology. The numerical model has been integrated in a user friendly operational system in order to provide useful information for the decision-makers in a crisis situation.

The model consists of a transport and a weathering module to represent the evolution of oil spilled in the marine environment. The transport module derives from the model developed by IHCantabria as part of the operational forecasting system created to respond to the Prestige oil spill (Galicia, 2002). The weathering module takes into account the main physical and chemical processes at local (harbours, bays and estuaries) and regional scale (offshore). Forcing data (wind, currents and waves) required by the oil spill model are provided by several national and international met-ocean operational systems and are available in Near Real Time to TESEO by FTP. The model provides in real time short-term (2-5 days) oil spill trajectories and weathering forecasting and backtracking to determine the likely spill site position.

APPLICATIONS

TESEO has been used during Don Pedro oil spill (Eivissa Island, Spain, 2007), during oil spill incidents in marine oil and gas facilities and to develop oil spill management systems at regional scale (offshore) and local scale (bays, harbours and estuaries). Moreover, the model has been applied in different oil spill exercises carried out by the Spanish Maritime Safety and Rescue Agency in the Mediterranean Sea (Exercises "Baleares 2005", "Tarragona 2008"), and the Atlantic (Exercises "Gijón 2006", "Finisterre 2006", "Gascogne 2007", "Vigo 2007" and "Santander 2010"). The model has been extensively calibrated and validated with drifter buoys exercises (e.g. Gulf of Biscay, North Sea, Belfast Lough, Huelva’s Estuary and Algeciras Bay) and laboratory tests carried out by CEDRE in the framework of SPRES project (2012-2014, Interreg, Atlantic Area).

SMC002                   

 

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.

SMC004

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:

Pre-processing module,

short-term module

medium and long term module

terrain module

TSUSY (Tsunami Simulation System) is a tool developed at IH Cantabria which allows us to carry out real time numerical propagation of tsunamis.

When an earthquake generates a tsunami,  IH Cantabria is able to offer, thanks to TSUSY, relevant data in a short period time. The software provides maps including travel time for the tsunami wave from the epicenter to the coast, as well as an order of magnitude of the maximum wave height to be expected in the different areas affected by the tsunami.

 

TSUSYTSUSY Maximum wave heights and travel times (Tsunami in Japan March 11, 2011)

 

To carry out these simulations, TSUSY uses the parameters characterizing the earthquake provided by the USGS (U.S. Geological Survey) as soon as the earthquake takes place. With them, the tool performs the C3 model, also developed at  IH Cantabria, based on COMCOT. This model solves "Shallow Water Equations" in a series of meshes with a global bathymetry, to calculate the results anywhere in the world.

The aqualab system provides a graphic interface with a series of numerical models developped by IH Cantabria which allow us to define the hydrodynamic characteristics of the littoral environment as well as the transport analysis of pollutants.

This interface has a series of tools to help generate date bases with geographical, meteorological and oceanogrpahic data, which can then be introduced iinto the models, facilitating their use as well as the graphical representation of the model's numerical results.

Aqualab allows the user to work with two and three dimensional hydrodynamic marine data provided by tidal currents and wind on coastal areas and shallow estuaries, all of which facilitatite the downscaling techniques.

The numerical tools used to manage water quality provide models of the spatial and temporal evolution of contaminant substances such as fecal contaminant indicators, levels of DO or organic material.

msp1Conforme el oleaje se aproxima y propaga hacia la costa, éste sufre una transformación energética debida principalmente a la influencia de los contornos batimétricos, es decir que en general, el oleaje experimenta los efectos propios de la refracción, difracción, asomeramiento y disipación de energía debida a la fricción con el fondo. Cuando el oleaje se encuentra con estructuras de protección costera y/o instalaciones portuarias, aparecen procesos de reflexión de oleaje, interacción oleaje-estructura y en ocasiones, disipación de oleaje por efecto de la rotura.

En la actualidad, los modelos que se basan en las ecuaciones elípticas de la pendiente suave (elliptic mild slope equations), son los más empleados para este tipo de estudios, y ofrecen una manera práctica y eficaz, para evaluar adecuadamente la agitación portuaria, considerando contornos batimétricos reales, batimetrías complejas, para oleaje irregular.

Este tipo de modelos son capaces de resolver en un dominio numérico bidimensional, los procesos lineales de refracción, difracción, asomeramiento, y reflexión (total y parcial), y los procesos de disipación de energía del flujo por fricción y rotura del oleaje.

msp2El modelo numérico MSP, se basa en la aproximación elíptica de las ecuaciones de la pendiente suave, propuestas originalmente por Berkhoff (1972, 1976).

Estas ecuaciones resuelven el flujo oscilatorio dentro de geometrías portuarias complejas y sobre batimetrías reales, teniendo en cuenta forzamientos monocromáticos e irregulares de oleaje multidireccional.

Se trata de un modelo altamente versátil ya que permite analizar de forma sencilla y computacionalmente eficiente los patrones de agitación dentro y fuera de cualquier puerto ya sea de nueva construcción o una revisión de un puerto existente. El modelo permite, una vez configurada la geometría portuaria inicial, estudiar infinidad de alternativas, oleajes y casos de mejora / ampliación de cualquier puerto.

El modelo MSP Resuelve los patrones estacionarios de propagación de oleaje y las ondas largas, su transformación reflexión y agitación, dentro de dominios numéricos con contornos complejos, sobre batimetrías reales, a través de la utilización de mallas adaptativas en elementos finitos y resolviendo los patrones bidimensionales (2DH) de velocidades, superficie libre y altura de ola, considerando los procesos de asomeramiento, refracción, difracción, reflexión parcial y radiación del oleaje hacia el exterior del puerto.

Este modelo ha sido aplicado con éxito en diferentes proyectos nacionales e internacionales, tales como: msp3

o   Prediseño y diseño de nuevas instalaciones portuarias
o   Estudios lineales de resonancia en puertos
o   Estudios de operatividad y gestión portuaria

bouss1The numerical model IH-Bouss, based originally on the non-linear modified and dispersive equations of Boussinesq, Nwogu (1993); Woo & Liu (2004a), Woo & Liu (2004b), Losada et al. (2008) y Kim el al (2009).

It solves the time patterns of wave propagation, transformation and agitation within the numerical domains of complex contours , on actual bathymetries be means of regular grids in finite volumes while resolving the two-dimensional patterns of the velocity, pressures and free surface considering the shoaling, refraction, difraction and run-up processes on the beach and port structures as well as the wave reflection and  radiation.

Moreover, the numerical model includes in its formulation the disipation processes due to partial or total absorption of the contours, processes related with the wave-breaking, bottom friction and turbulent effects.

One of the main advantages of using IH-Boussinesq is that it is based on teh advanced capabilities to solve wave patters on a nuerical domain with real complex contours while considering a temporal evolution of these patterns. It also solves the velocities, pressures and free surface in the two-dimensional plane. It can also solve the energetic transformation of the wave spectrum as it propagates and interacts with the bathymetric sea bed and the port contours thereby allowing the energetic interaction of the different frquential components of the flow. (i.e. long and short wave)

Additionally, IH-Bouss is able to evaluate the run-up on beaches and port structures as well as the flooding caused by waves and tsunamis.

Finally, IH-Bouss Fcanbe applied to the large extensions, in the order of kilometera with an efficient computational time and competitively, allowing it to be included as one of the main tools in the in coastal and port engineering, as the code has been paralelized.

brIHne tools

The brIHne models have been developed within the research areas dedicated to discharge  to simulate the brine discharges into the sea produced by desalinization plants.

These models are based on numerical approximations which have been validated by the scientific community and also by high quality experimental data, obtained through the tests carried out at IH Cantabria's facilities with advances optical techniques. This validation with experimental data publishe dby other authors show that the brIHne models are an improved alternative to existing commerical models such as CORJET, UM3 orJetLag.

The brIHne models are continuously being updated and improved, so as to include new parameters and discharge configurations. To date, the following models are available together with the necessary technical specs to make them user friendly.

The access to these models is via the website www.medvsa.es  after having previously taken the course offered by IH Cantabria which will train the user on how to manage the tools.
