Scour or landslide is a problem that occurs at river bends. Many methods are used for scouring or landslide protection. One of the protections for scouring construction is crib model by using gabions and current-aligning bamboo. The purpose of this study is to determine of the effect of variations in the placement of the crib by using of gabions model and the current-aligning bamboo on the river bends. This research is an experimental test of the hydraulic model using river flume model with 5m on bend length, 0.8m width, 0.5m height and a constant discharge of 7.07lt/sec. The test consists of testing control, that is a bend without reinforcement and testing with reinforcement at the bends. The reinforcement at the bends using placement variation was twice carried out with the variation 1 consisted of 3 current-aligning bamboo, 4 gabions, 3 current-aligning bamboo and the variation 2 contains the opposite. The test results showed that the maximum scouring occurs in variation 1 with -5.4cm, -5.2cm on landslides and 0.61cm on scour. The results of the Surfer App and cross sections of stations P00 until P07 are more effective using gabions, while P08 through P24 are more effective using current-aligning bamboo.

冲刷或滑坡是在河流弯道处发生的问题。许多方法用于冲刷或滑坡保护。冲刷施工的保护之一是使用石笼和顺流竹的婴儿床模型。本研究的目的是通过使用石笼模型和河流弯道上的电流对齐竹子来确定婴儿床放置变化的影响。本研究是利用河流水槽模型对弯曲长度为 5m，宽度为 0.8m，高度为 0.5m，恒定流量为 7.07lt/sec 的水力模型进行实验测试。测试包括测试控制，即没有钢筋的弯曲和在弯曲处有钢筋的测试。使用位置变化在弯曲处进行了两次加固，变化 1 由 3 个电流对齐竹子、4 个石笼、3 电流对齐的竹子和变体 2 包含相反的内容。试验结果表明，最大冲刷发生在变化1，滑坡-5.4cm，-5.2cm，冲刷0.61cm。Surfer App 的结果和 P00 到 P07 站的横截面使用石笼更有效，而 P08 到 P24 使用顺流竹更有效。
