The graph above shows the progression of the tide at Roompot buiten (SVKO) see. The blue line follows the astronomical tide forecast in NAP, which is the data that you also see in the table on the left in the '10 min' column. The orange line, however, shows the astronomical forecast plus - or minus - the setup. The influences of the weather and current are therefore included, so that the orange line represents the most likely scenario. About the reference planes (NAP and LAT)
A standard difference between NAP and LAT is known for each tidal location, the standard difference between NAP and LAT at Roompot buiten (SVKO) is: 189 cm
