Abstract: This paper presents a 3D eutrophication model established for the Maracaibo system. The model is an add-on module to a hydrodynamic model established for the system, including Lake Maracaibo, Maracaibo Strait, Tablazo Bay and the Gulf of Venezuela. The model represents in detail the important features of the complicated system: the nutrient loading, the production and degradation of phytoplankton, the settling of detritus, oxygen conditions and the important effects from saline intrusions and density stratification in the Lake. The modeling periods using this system model made up a total of 16months. Furthermore, a 10-year Lake simulation was performed to analyze the effect of interannual variations in the run-off to the Lake on the eutrophication conditions. A short description of the intra-annual variations in the system based on the simulations is given.
