Abstract
The hydrodynamic equations are a set of equations that describe themovement of a water body through a set of variables, the so-called state variables. The basic equations that govern the development of these variables can be derived in its full form through the application of conservation laws. In sea water 7 variables completely define the state of the fluid. These variables are the density ρ of the water, the three velocity components u, v, w in the direction of x, y, z, the pressure p, the temperature T and the salinity S. If only fresh water systems are concerned, there is no salinity as a variable, reducing the number of state variables to 6.
