- ABSTRACT A field study to determine water discharge distribution with respect to time and location as a result of rotational irrigation system has been conducted in the Maneugteung Irrigation Scheme (MIS), Cirebon, West Jawa . Data of flow characteristics in term of flow velocity and discharges under existing canal condition and system management were collected during dry season, during which a rotational water distribution system was applied in the scheme. The flow velocity and discharge of each canal section were measured by current meter. Results of the measurement then were used to develop relationships between canal length and cumulative time required to travel and to attain normal flow depth of each canal section. Result of the study reveals there was a significant time lag between the time of release and time of arrival at a particular site in the assigned open channel. This- means that irrigation water availability along the canal varies depend on water discharge, flow depth and physical condition of the canal. Attempting to obtain equity in water distribution among water users, it is suggested that the travel time and time to attain normal flow depth have to be added to the allocated time for distributing water for each irrigation block.
