The research is aimed to analyze the magnitude of the speed of the flow that is made out of some roughness channels are different. Research is carried out in line Secondary Regional Irrigation Alitta village Bentenge Subdistrict Paleteang district Pinrang. Channels that are reviewed are the channel secondary which is made of some roughness channel are different by opening the doors as deep as 20 cm, 30 cm, and 40 cm. The results of the study indicate that happens changes the speed of each roughness channel. It is caused by the difference in the roughness of each channel and the sedimentation of each channel. ## Keywords - Channel (broadcasting) - Surface finish - Flow (mathematics) - Sedimentation - Hydraulic roughness - Open-channel flow - Surface roughness - Mechanics - Geology - Hydrology (agriculture) - Materials science - Geotechnical engineering - Geomorphology - Engineering - Electrical engineering - Composite material - Physics - Sediment --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
