The river plume behavior after high freshwater inflow in Suo-Nada is examined by means of analyzing historical data of salinity and Yamakuni River runoff. The salinity dataset classified according to the history of river runoff provides pseudo time series of the salinity distribution. It is found that, one to two weeks after the high river discharge, the less saline water mass concentrates especially in the western part of Suo-Nada. This result is consistent with a fact that the oxygen-deficient water mass is generated in the western part of Suo-Nada.
