Density currents are the main cause for sediment transport in dams reservoirs and seas deltas. One of the problem solution is to reduce or eliminate the effect of them using completely block the density current and as a result the sediment settle far away from the dam in strolling of density current, some experiment were carried out on a flume in water Sciences Engineering Laboratory, Shahid Chamran University of Ahwaz. In this research density current were provided using sediments with d50 of 28.9 µm and passing flow from obstacle was investigated under different bed slopes and discharges. The obtained results show that the effect of obstacle for sub-critical flow is more than supercritical flow. However it was found that even for supercritical flow obstacles are considerably effective on preventing of density current flow.
