CMS-Flow:Boundary Conditions

Tidal Constituent

The CMS follows the National Oceanographic and Atmospheric Administration (NOAA) National Ocean Service (NOS) convention for astronomical water level predictions. The water level predictions are based on a harmonic equation with several arguments

$\eta =\sum _{i=1}^{N}fA\cos(\omega _{i}t+V_{0i}+u_{i}-\kappa _{i})$
