Acids, Bases, and the Dissociation of Water

In any sample of water, very few of the molecules are dissociated at any one time: in fact, only about one in 550 million. There is, however, a constant change; as one hydrogen ion reattaches to a hydroxide ion to form a water molecule, another water molecule dissociates to replace the hydrogen ion and the hydroxide ion in solution.

Hydrodynamics

Hydrodynamic modelling is central in most modelling tasks in the marine area. Apart from being important in itself, it also forms the basis for a number of other tasks, such as sediment transport simulations, different kinds of spreading and dispersion studies and studies of water quality or ecological systems.

It's the same idea as your water tail correction but it derives an average dispersion coefficient from the whole system rather than only considering water.

Dispersion (water waves)

In fluid dynamics, dispersion of water waves generally refers to frequency dispersion, which means that waves of different wavelengths travel at different phase speeds.Water waves, in this context, are waves propagating on the water surface, with gravity and surface tension as the restoring forces.As a result, water with a free surface is generally considered to be a dispersive medium.
