Abstract
Â
Sedimentation represent big threat to continuity a barrage building. Barrage function as reservoir will decrease in line with decreasing volume at the same time with effect of existence of sedimentation. There is two kinds of way of to overcome the problem of sediment barrage, that is with operation entry of sediment to reservoir area by removing sediment from barrage.
 Till in this time handling of[is problem of sediment not yet produced fruit satisfying result. Considering is important of function from barrage hence needing the effort by is assorted way of, one of them cleaning with systems usage of pipe suck adrift, this cleaning is relied on gravitation stream theory as well as calculation charge current in pipe capable to lift sediment which have tuanged barrage base.
 Item turbulensi theory sediment lifting at open channel stream, item will be upraised if stream turbulensi can generate style box exceeding sediment item gravity

Key words : Pipe suck adrift, Sedimentation.
