This study use ten porous cylinders as experimental models, measured the river bed topography at each time point by change the set distance, the angle between flow and porous cylinder group, and the height of porous cylinders, discussed (1) river bed topography different between each groups, (2) the same height of the porous cylinders but different setting distance, (3) when porous cylinders group was submerged, (4) the same setting distance between each porous cylinder but different height, and (5) the flow diversion effect by porous cylinders group at different set up conditions. According to the results, the interval between each cylinder center of the circle 2 times the diameter of the porous cylinder, and the setting angle between flow and porous cylinder group is 30 degrees, we can get the best efficacy of sediment deposition.
