Résumé :	This study was conducted to estimate the horizontal and vertical exchange of water in response to meteorological effects in Inohana Lake, Japan. To examine the horizontal water flow between Hamana and Inohana Lakes while monitoring horizontal and vertical exchanges of water within the lake, we determined the current velocity, salinity, and water density in the field. We performed regression analysis of the relationship between meteorological factors such as wind and rain and the horizontal water flow between the two lakes. This information was then used to construct a simple box model to estimate the average water exchange and evaluate the meteorological effect based on the average salinity and river discharge. These results revealed that the surface water-volume flux in the channel was heavily influenced by the north-south wind intensity. These findings indicate that a box model is capable of providing a good estimate of the summer-averaged water flow and the exchange rate that is influenced by wind and rain.
