碩士 === 國立成功大學 === 水利及海洋工程學系碩博士班 === 97 === This paper is about protecting the concave bank by Cheng-Kung Porous Basket (CKPB) in a curve channel. By the experiment, we can find the CKPB can make a slow water velocity area behind it, and also guide the main stream away from the concave bank. The result tell us that the CKPB in the best set (the long is 0.57 times channel wide, the angle with the tangent line is 30° and location at 37° in the curve channel), the protecting efficiency up to 64.7%, it shows the way provide excellent protection against girdle scouring.
