Resistance of pipe flow with a stationary bed and with bed load on sediment deposition in pipes is discussed theoretically and experimentally, in which water flow area and hydraulic radius in a cross section of the pipe is divided into two parts: area and hydraulic radius influenced by smooth pipe wall and those by rough sediment wall. Experimental results about mean velocity and sediment transport rate in a pipe proved that the division of hydraulic radius of the water flow area into two is
