Summary
The basic quantitative tools to study the hydrodynamics, and any suspended and dissolved matter in water, of semi-enclosed basins are the conservation equations. Conservation of momentum and conservation of mass are used for water motion, while conservation of salt and conservation of heat address their distribution in space and time. An equation of state, the Thermodynamic Equation of Seawater, relates temperature (heat content in the water column), salinity, and pressure to water density, which plays a dynamic role in the conservation of momentum. The conservation of suspended or dissolved matter has an advective contribution that depends on water motion, a diffusive contribution, and a source/sink contribution. The source/sink contribution represents the greatest uncertainty in water-related studies.
