Eutrophication mechanisms of narrow and deep Dokai Bay and wide and shallow Hakata Bay are compared on the basis of observed salinity, TP and TN data. Nutrients assimilated to phytoplankton in the euphotic layer sink to the aphotic layer and they are advected to the bayhead by the developed estuarine circulation in narrow and deep Dokai Bay. Therefore, the average residence times of TP and TN in Dokai Bay are two times as that of freshwater, while the average residence times of TP and TN are nearly the same as that of freshwater in wide and shallow Hakata Bay. Therefore, narrow and deep Dokai Bay is easy to eutrophicate although the average residence time of freshwater is short.
