EFDC_Explorer provides a Tide Generator Tool for generating a pressure time series computed as astronomical tidal forcing.
The basic formula for the oscillation of water level due to astronomical tides is based on the combination of the tidal constituents as follows:
In which
η = tide level (m)
z0 = mean sea level above the datum (m)
fi = nodal coefficient to adjust amplitude for the ith component
Hi = amplitude of the ith component (m)
ωi = speed or angular velocity of the ith component (radians per second)
t = time (s)
(V0 + u)i = astronomical arguments of the ith component
gi = phase lag of the ith component from Greenwich longitude
It should be noted that the units used in EE can be changed so that they are convenient for the users.
