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.
