- The Tides and Tidal Circulation of Todos os Santos Bay, Northeast Brazil: a general characterization Abílo C. S. P. Bittencourt José M.L. Dominguez Arno Brichta Guilherme C. Lessa Multidisciplinaria (Ciencias Naturales y Exactas) Tides Tidal currents Baía de Todos os Santos The Todos os Santos Bay, located on northeastern Brazil, is the second largest coastal bay in the country,after São Marcos Bay. The three main drainage basins convey an average of 120 m3/s of freshwater towardsthe bay, the majority of it, however, held by a dam in Paraguaçu River since 1985. The original averagefreshwater inflow was two orders of magnitude smaller than the estimated tidal discharge through the mainbay entrance, and the oceanographic characteristics of the bay, as indicated by bay salinity measurements,are clearly marine. The tides are semi-diurnal, and are amplified up the bay by a factor of 1.5. Shallow waterconstituents become more important as the tide propagates along Paraguaçu Channel and Paraguaçu River,where they generate time asymmetries that change between spring and neap tides. Currents in the bay aremainly bi-directional, and are stronger during the ebbing tide in most of the bay. Offshore, relatively strongtidal currents appear to be felt in a radius of about 10 km, where they are superimposed on winds drivencurrents orientated to the southwest. 2001 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32773209 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.2 Vol.73
