Abstract

Deposition of sediment inside the conduit structures reduces the flow cross section area and increases the flow roughness which causes reduction of flow discharge passing through the conduit. Among the methods which can prevent sediment deposition is non sedimentation condition in the structure, since the critical section of the inverted siphon in sedimentation is the outlet. In the beginning of this research, a general relationship for conditions of incipient motion that is minimum of non sedimentation in the outlet of KARKHE INVERTED SIPHON was developed by applying the dimensional analysis. Then experimental tests were conducted by using PHYSICAL MODEL and 5 non-cohesive sediment with dimensions of 0.5, 0.7, 1, 2 and 3.2 mm and one graphs was drown that can be used for determining non-sedimentation in outlet conduit of KARKHE INVERTED SIPHON. Then, by using this graph and suspended load particle size distribution curves of the Karkheh River in Hamidiyeh diversion dam, minimum non sedimentation velocity was extracted for prevent sediment particle diameter of 1.5 mm that is the largest particle size input to upstream channel of KARKHE INVERTED SIPHON from Hamidiyeh diversion dam, were determined. The results show there is a non-sedimentation condition in the Karkheh inverted siphon in designed discharge and velocity.
