Abstract

This invention concerns a method for calculating a normal water level at a measurement point (15) in an ocean, lake or waterway. The method is charcacterized in that a first water level (3) is recorded at a control point (10) relative to a reference ellopsoid (11), which control point has a precisely calculated normal water level (ho). In addition, a second water level (3) is recorded at the measurement point (15) relative to the reference ellipsoid (11). The two recorded measurements are then correlated with one another to calculate the normal water level at the measurement point (15) relative to the reference ellipsoid (11).
