Abstract
The present paper shows the effect of the Isahaya Sea Dyke on the baroclinic structure due to freshwater inflow from rivers in the Ariake Sea. Numerical simulation of tidal current and salinity stratification was conducted in case of rainy season in 2006 with and without the dyke.<br> As a result, the followings were cralified:<br> 1) The dyke can decrease the velocity of tidal current and strengthen salinewater and freshwater stratification in Isahaya Bay and in coastal area off Shimabara Penninsula; 2) Stratification can be seen to be strengthened in a term from neap tide to spring one; and 3)The influence of the dyke on baroclinic structure due to freshwater inflow depends on conbination of tide and flow rate of rivers.
