ABSTRACT
A Numerical model for calculatinq M2 – Independent Tide in the
Mediterranean (as a closed basin) has been developed. The sea was
considered, firstly, as composed of two communicated rectanqular areas
of constant depth of 500 mwith a resolution of 1° X1° , secondly, as
bounded nearly with its natural coastal and bottom confiqurations and
tested twice with resolutions of 1° X 10 and 15′ X 15′ respectively.
The sea is assumed to be driven by the potential tidal forces.
The computed amplitudes and phases obtained from the proposed cases
were compared with each other and also with observations. The deduced
values obtained from rectanqular basins type with constant depth of
500 m are relatively qreater than that calculated by the real
boundaries type. Meanwhile, the results of the model with finer qrid
resolution 15′ X 15′ are more siqnificant than that with resolution
of qrid 1° X 1° and more confirmative with observations. The
boundaries have minor influences while the dimensions of the basins
have siqnificant impacts on the tidal pattern.
