About the Inflence of the Deflector Flow through Curved River -The effect by change of curvature-

Abstract

In recent years, the river is made in consideration of environment or the scenery. This research inserts deflector in a curved river, changes the direction of the streamline through a curve and thereby, and makes the influence of the flow by curve ease. Length is made in to 40% of river width when inserting deflector in a curved river. If an insertion position is inserted in 63% lower stream of a curve, it is effective in direction change of a streamline. Moreover, if deflector is inserted by plurality rather than the singular, a big effect will be acquired to a direction change of a streamline. However, it becomes the cause of making the streamline of a down-stream region producing disorder, and has left some problems. This research experiments by changing the curvature of a curve, and reports the result examined about the validity of the deflector by change of curvature.
