Abstract
Lake Abashiri, located in the northeast of Hokkaido, has stratified layers of fresh and salt water. The biochemical pollution is caused by inflowing load from the catchment area, and no oxygen state of the lower salt layer is becoming a serious problem. In this paper, a numerical model is proposed to investigate the hydraulics of the lake, river and sea region. A general non-orthogonal coordinate system is used to cover the complex boundary condition of the region, and three-dimensional time dependent momentum and continuity equations are used in the model. The model is verified using the two characteristic dataset obtained by field observation. Results obtained by the model agree well with those of the observeton. It is apparent that the model can be a powerful tool for predicting the lake hydraulics.
