The objective of this study was to analyze the effectiveness of sediment flushing system of BY PASS channel with 1 door, 2 door and 3 door at a floodway. To determine which was the most effective, empirical model of effectiveness of each channel of sediment flushing were built. The object model of this study was the Floodway Sedayu Lawas, located in Lamongan, East Java Province. This study uses Hydraulic Physical Model Test. Built and test the model conductedin the Laboratory of River, in Surakarta, Cental of Java. The variables of this study were sediment weight (W), water depth(H), sediment mass density (Ïs), sediment diameter (ds), waterflow rate (Q), and floodway wide (Bo)
