In recent years, Lake Abashiri has been confronted with serious problems due to water accidents induced by aoshio and eutrophication. By using a fish detector and ADCP, we could make clear the spatial and temporal structure of density stratified flow, theshort-term behaviors of salinocline (halocline) just after the occurrence of aoshio, and the overall characteristics of the flow in this lake. Based on the results of the observation, we carried out the numerical analysis regarding to the time-varying behaviors of the density interface and the wind-driven flow. Comparing the calculation results with field data, we could evaluate the influence of wind, the horizontal and vertical structure of the lake on the flow and the behaviors of salinocline.
