In this paper we examine thc low frcsuency movcmam (o 0.1 cyclcs-day) in uie differmt water bodies within thi system.
The harmonic and rorary specaal analyscs of velocity data indicatcs the importante of tidai forcing within thc whole system and its intaauion with winds and fresh warcr discbarge.
ln particular,the nsults indicate thc exist e of ~ dominant s e m i - m d y osciUarions in iak Maracáibo.

Any dynamicd study of an estuarine system has to include both current and density distributions, simply because rhey are deeply i n t e ~ c o ~ e ~ tThe ed. relative forcing of river discharge and tidal range, togefher with the effect of winds, waves, and the geomorphology of the basin, will determine the Ievel of vertical and horizontal stratification.In particular, stratif~cationwill be modified as the tidal current changes its strength through an individual tidal cycle or the neap-spnng cycle: either by differential horizontal advection or through shear-induced mixing.
This results in a rapid response of h e estuarine system and makes it difficult to assess the principal factors respnsihk f ...
