FIELD: ebb maps composing technologies.
SUBSTANCE: method includes determining ebb height with consideration of angular speed of harmonic component of tide. Real plan coordinates of area of water, directed to east and north, are determined respectively. Value of ebb height of harmonic component of tide in fixed time moment is determined through projection of point on phase circle, appropriate for current height of sea level, parameters of which are determined with consideration of position of inner points of area of water and its contour. Oscillations amplitude of harmonic component of wave is determined on basis of values of ebb height in points with real plan coordinates for serial set of discontinuous time values, on basis of values of which maximum ebb level time is determined.
EFFECT: lower laboriousness, higher trustworthiness.
