Waves generated by the wind is the principal driving force in the coastal environment; wave data for different coastal locations are provided here.
Currents unlike waves are translatory motion in the sea and are responsible for sediment transport in the coastal zone.
The sea level is very dynamic, keeps fluctuating due to waves, tides and other forcing factors. The mean sea level is on the rise due to global warming.
The underwater topography in the seas is provided by bathymetry; bathymetry plays an important role in the coastal processes.
