Lake Abashiri is a brackish lake located at Abashiri river mouth and forms two-layer structure of salt and fresh water. Here, we analyze the long-term. behaviors of the halocline, defined as boundary of the two layers, from time series of annual precipitation and discharge in Abashiri river basin. Using a echo sounder for taking photographes of the halocline, we could show short-terth behavior of the halocline caused by snow melt flood, strong wind and the intrusion of salt water to this lake from the sea during flood tide. We carried out numerical analysis regarding the short-term behaviors of the two layers in Lake Abashiri when the wind is blowing hard.
