Abstract


Theconstructionofadaminarivershallreducethesedimentflowintodownstreamfaceofdamstructure,sothat many problems such as river bed degradation, or destruction of the river environment shall be
encounteredin this part of river.Additionally, sedimentation shall also occur in the reservoir which likewisemay decrease the reservoir storage capacity.Related with these problems, a technology is to be introduced
to drain sediment from the reservoir to downstream part of the dam.The conceptual technology of flowingsediment from the
reservoir into downstream part of the dam and thus reducing sediment in the reservoir,introducesthedesignofasedimentsuctionpipe. Inthiscontext,Pusairresearchershadstudiedtheinfluenceof the suction pipe design on the sediment flow by carrying out a physical model test at the HydraulicLaboratory of the Research Center for Water Resources.The designed sediment suction pipe the so calledsuction pipe technology consists of 4 types.Results of the flow test show that the sediment suction pipetechnology Type 4 can carry coarse sand material into the river downstream the dam more effectively than othertypes.
