In EFDC, the unit of harmonic constant "phase lag " in tidal analysis is “seconds”; but the common unit is “degree”, how to convert its unit between “seconds” and “degree”, thanks a lot!
the conversion may be made as follows:
phase = speed*time and speed = 360/period. In EFDC the period is in seconds so speed is degrees/second. Therefore:
phase [deg] = speed [deg/sec] * time [sec]
time [sec] = phase [deg] / speed [deg/sec]
