In this paper, the hydraulic design of Tamagawa Waterworks at Edo in the later Edo Era is discussed by use of historical literatures “Tamagawa Jyousui Tome”. The engineers recognized the hydraulic phenomena encountered at the combined flow of open channel and pipe. The inclination of the pipe networks of Tamagawa waterworks is similnr to that of modern sewer system. The pipe network is deigned on the sectional area and the depth of flow at the mouth ofindividual inlet.
