The 3-dimensional physical model is developed to reproduce the annual change in the physical environment in Lake Biwa. Numerical simulation is carried out under the actual boundary conditions such as meteorology and river. As a result, the model can predict well the basic characteristics of flow velocities and water temperature in summer, when several anticyclonic gyres are formed at the water surface by the topographic heat accumulation effect. As for the dynamics of water in winter, several cyclonic gyres induced by the same effect are reproduced in the numerical simulation, however the accuracy of the model is not validated enough. Hence more knowledge on the dynamics of water during autumn and winter seasons should be collected from observation or hydraulic model experiment to improve the accuracy of the model.
