MARCE

The MARCE project is funded by the Spanish National Plan I+D+I (2008-2011) for the years 2010-2012. The  objectives can be summarized into 2 large groups. The first involves the identification of the main biophysical relations related to variability in the river ecosystems. The main challenge is to quantify the relationships between hydrology, geomorphology, water quality and river biota, achallenging feat, mainly due to the lack of appropriate data (spatial and temporal continuity of records). Therefore, to achieve this goal, IH Cantabria is developing models that include all components of the river ecosystem for the entire domain of the project.

The second block aims to determine the ecological consequences of different human activities on river ecosystems, for this, our researchers are characterizing the degree of impact of different river sections using GIS tools to isolate effect of specific pressures using a Control-Impact design for each river component  (more info).

Three-dimensional modeling of wave interaction with Marine Structures MOTIOM  (MOdelado Tridimensional de la Interacción del oleaje con Obras Marítimas )


The
MOTIOM project (BIA2008 - 05462 ) has been developed in 2009-2011 within the Spanish National Research Plan (DO) .

The main objective of MOTIOM has been to improve the
three-dimensional modeling knowledge and capabilities of the processes carried out by the waves in the presence of coastal structures. Traditional analysis of these structures has been carried out experimentally, mainly using two-dimensional models, with the problems which arise in this type of experiemtns such as scale effects and the inability to reproduce natural conditions which occur under the maritime works. The methodology used in this project, which applies three-dimensional modeling of the Navier- Stokes equations and experimental data, has allowed the three-dimensional study of the processes generated by the waves surrounding coastal structures.

The method has been divided into two parts. Initially
the Navier-Stokes equations have been derived to model the flow in porous media, such as riprap protections or breakwaters, and aresolution system coupledwith the flow outside othe structure has been presented. The proposed method consists of the joint resolution of the pressure and velocity fields in both areas of the domain. Likewise, two turbulence models have been adapted, the k-e and the SST model, for flow in porous media. In the second phase of the project we have developed new algorithms to improve the generation of realistic wave conditions using RANS models. TO carry out this phase multidirectional wave algorithms of  short and long crested waves as well as for the waveve absortion have been developed. This has allowed for the reduction of the computational time , once one of the shortcomings of this type of models and their application to real case studies.

The new set of equations developed and the multi-directional generation-absortion numerical models have been validated in laboratory tests specifically designed for the project as well as other experiments found in the literature, obtaining a high degree of agreement between the measured variables and simulated. The tests were performed using vertical dike geometries and
rubble mound breakwaters, focusing on the analysis of processes such as over-topping, in which the wave conditions are mostly three dimensional, and the flow around breakwater nose.

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.

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 overall objective of the proposal is to develop data, methodologies and tools for the assessment of impacts and the identification of adaptation measures to respond to the needs of the Spanish National Climate Change Adaptation Plan in coastal areas using scientific, technical and socio-economic data, considering climate variability and climate change both in the present and in the future. Within the coastal zone, the plan focuses on flood and erosion risks and the possible impact on infrastructure, studying the impacts and adaptation for large coastal cities and the tourism industry. Th eplan also aims to develop new methodologies and tools developed which can then be used as a reference by the Nairobi Programme of the United Nations.

Specific objectives focus on specific results such as:

  • Methodologies and techniques for the development of digital databases of high temporal and spatial resolution of past and future marine climate in open water and reduced depth generation techniques comparing predictions / projections of future marine climate (extrapolation of trends from statistical analysis non-stationary, dynamic downscaling and statistical downscaling)
  • Recommended for use in different applications, impact assessments and adaptation strategies,
  • Development of impact indicators for different coastal areas including coastal management units and generation of an Impact atlas for the Spanish coast.
  • Applications of methodologies and tools to selected management units
  • Proposed actions to assess risk and to improve the adaptability and resilience of the management units considered and especially Spanish coastal towns, especially "sun and beach" tourism, to climate change
  • Development of techniques for adaptation "climate-proof".
  • Development of an Atlas, integrating the databases into a GIS, with easily manageable tools and methodological manuals making it user friendly for public authorities and national and international organizations.

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.
