抄録

In order to make clear the water temperature changes in Isahaya Regulation Pond, heat budget model was developed regarding the heat exchange at water surface. This model was applied to the real water body to simulate the temporal and spatial variations of flows and water temperature caused by the intake of seawater. Calculated results show that the introduced seawater flows in lower layer towards innermost area, and induces the vertical circulation flow in this pond. Accordingly, water temperature distribution are strongly affected by the up- and down-welling flows as well as the heat exchanges at water surface.
