In fluid dynamics, wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques.These simulations consider atmospheric wind forcing, nonlinear wave interactions, and frictional dissipation, and they output statistics describing wave heights, periods, and propagation directions for regional seas or global oceans.
If there is long-term wave data available in a nearby offshore location (e.g. from satellites), a wind wave model can be employed to transform the offshore wave statistics to the nearshore location (provided the bathymetry is known). Often, long-term local measurements of wave conditions due to extreme events (e.g. hurricanes) are missing.
The coastal environment produces challenges specific for this branch of engineering: waves, storm surges, tides, tsunamis, sea level changes, sea water and the marine ecosystem. Most often, in coastal engineering projects there is a need for metocean conditions : local wind and wave climate, as well as statistics for and information on other ...
Marine geology also has many applications on the subject of offshore energy development. [55] Offshore energy is the generation of electricity using ocean-based resources. This includes using wind , thermal [ clarification needed ] , wave , and tidal movement to convert to energy. [ 56 ]
Offshore structures are exposed to various environmental loads: wind, waves, currents and, in cold oceans, sea ice and icebergs. [6] [7] Environmental loads act primarily in the horizontal direction, but also have a vertical component.
Regional Ocean Modeling System (ROMS) is a free-surface, terrain-following, primitive equations ocean model widely used by the scientific community for a diverse range of applications. The model is developed and supported by researchers at the Rutgers University , University of California Los Angeles and contributors worldwide.
New development in ocean sensors and systems, including improved bio-fouling protection, autonomous water sampling systems, optical and acoustic systems, airborne variable sensors, and two-way, low-cost, low-power telecommunications.
Wind resource map for the Philippines, from the Global Wind Atlas. High resolution mapping of wind power resource potential has traditionally been carried out at the country level by government or research agencies, in part due to the complexity of the process and the intensive computing requirements involved.
