Beside current direction, the salinity was meaningful for the investigation of the hydrodynamic connectivity, as the Taperaçu and Caeté waters show important salinity differences. −1 during neap tides, whereas during the spring tide the SSC reached 2 g.L −1 at the Taperaçu and 1.5 g.L −1 at the Caeté side. During dry season velocities were smaller, especially during the ebb.
During the wet season the depth-integrated ebb current velocity reached 1.5 m.s −1 at the Taperaçu side and 1.4 m.s −1 at Caeté side, whereas during the flood it reached 0.9 and 0.8 m.s −1 at Taperaçu and Caeté sides, respectively. On the other hand, the flood phase is longer and takes place first and reaches higher levels at the Caeté side in comparison to the Taperaçu side, despite neap/spring or wet/dry variations. The results have showed a strong tidal asymmetry, with ebb phases lasting approx. The measuring campaigns were carried out during neap and spring tides, including also the wet and dry seasons. Water levels, currents, salinity and suspended solid concentration (SSC) were measured at both ends and at the middle of the channel. The hydrodynamic connectivity between the Taperaçu and the Caeté estuaries at the east sector of the Amazon Coastal Zone, through the Taici channel was investigated.
