Water Level

Water Level and Current Velocity

Tidal Constituent

The water level predictions are based on a harmonic equation with several arguments

  (1)

where is the constituent mean amplitude, is a factor that reduces the mean amplitude and varies in time, are the constituents equilibrium phase and is the constituent phase lag or epoch.

Flux

The water flux is specified as m^3/sec per cell along the cell string. This value is multiplied by the number of cells in the cell string to obtain the total flux. The total flux is then redistributed along the boundary according to
