The fresh-water discharge in Todos os Santos Bay (BA) an its significance to the general water circulation

Abstract

Fresh water discharge into Todos os Santos Bay is assessed on the basis of measured and estimated river discharge data. The average mean fresh water discharge amounts to 111.1 m³s^-1, and might be added to another 28.2 m³s^-1 that falls directly on the bay area as rainfall. The mean river discharge represents only 0.08% of the spring tidal prism, calculated by the means of a through analysis of the depth area distribution.
