Table 1. The values of parameter in the Eq. (1).

Parameters	Values
L	The value of datum, which is the height of the depth datum below mean sea level.
ΔLi	The value of datum deviation at gauging station i, which is the datum deviation between datum value of predicted water level with simulated water level.
L P i	The datum value of predicted water level at gauging station i.
L M i	The datum value of simulated water level at gauging station i.
f	The nodal variations of the partial tides.
H	The amplitude of the partial tides, usually given in feet or meters.
g	The epoch of partial tide, usually expressed in degrees.
φ	The phase angle, the range is 0–360° .
