Eulerian profiles of thermohaline properties and currents have been sampled in the Peruípe River Estuary (Nova Viçosa, BA), southern region of the Caravelas-Peruípe Rivers Estuarine System. One station was located near the mouth (C) and other one up the estuary (E). The Hansen-Rattray diagram classification of the upper reaches of the Peruípe river estuary in the wet season changed from Type 2b (partially mixed and highly stratified  =0.88) to Type 1b (highly stratified  ~1.00) due to the fortnightly tidal modulation. This region was mainly forced by river discharge (Ri E =5.7 and Ri E =4.1) and characterized by high (Ri L >20) and low stabilities (Ri L <20) in the neap and spring tidal cycles. However, near the mouth stratification was strongly modulated by the tide, and its classification alternates from being highly stratified (Type 2b  =0.92) in the neap tide to being well mixed with low stratification (Type 1a  =1.00); the mouth was dominated by fresh water discharge (Ri E =12.9) and tidal stirring (Ri E =0.6) in the neap and spring tide, respectively, and were associated with high and low stabilities. The classical steady-state salinity and velocity profiles show good agreement (Skill~1.0) with the corresponding observational profiles when simulated with

Nenhuma palavra seria suficiente para agradecer ao Sr. Tomás, Sra. Suely e Srta. Mariana, pois tudo que sou devo à vocês. Obrigado por moldarem meu caráter e me mostrarem o valor da vida. Ao Eduardo Siegle, à quem considero não apenas o Prof. Dr. que me orientou neste trabalho, mas pela amizade reforçada nestes últimos anos. Tenho a honra de considerar você e sua família como meus amigos.
