抄録

When the high concentrated turbid water enters into a reservoir and collides at the dam, an internal surge is formed. With the repetition of the surge, the turbid water spreads in an extensive space of reservoir. The understanding of behavior of the surge is necessary to manage properly the water quality in the reservoir. As a reservoir has in general a three-dimensional geometry, the behavior of surge seems to be different from that of the two-dimensional surge. In this study, the experiments of internal surge are carried out by using the three-dimensional reservoir model with gradual change in channel cross-section. It is shown that the motion of surge is considerably affected by a reservoir geometry and by the selective outflow. Theoretical investigation is also made on the height and the advance speed of surge.
