Abstract

 In Lake Komuke, which is one of the most significant lakes for immigration birds, we carried out field experiments of flow field and water quality. Lake Komuke consists of a main lake and the other two small lakes. The main lake is found to have higher salinity compared to the other two small lakes. During the snow melt period, the small lakes are found to have less salinity compared to summer, which is confirmed by the numerical computations using three-dimensional numerical model. As a result, tidal flats in the small lakes have larger residual time of sea water which is significant for immigration birds.
