Abstract

The safe flow velocity, one of them is influenced by turn problem. The more turn, moreover in area with. In a slope area with the small gradient, the water flow will be much slower. Hence, there should be the velocity measurement flow at any turn to know the tremendous influences toward the velocity of the gradient drift in turn flow. To know the geometric influences of flow toward turn and the velocity of the secure flow to identify factors that influence velocity of secure flow at the flow turn. The research were take place at Sesaot irrigation area West Lombok. Using an experimental method by measuring at the field. The primer datas were taken from the observation and straight measurement at the location, and the secondary datas were taken from the related institutions. Then , the datas were analized to get the evaluation result of the flow velocity, canal geometry, flowrate, and the canal condition at the research field. The result showed that the effect of curves on the secondary channel in irrigated areas Sesaot cause further slowing the flow velocity in the channel, the flow velocity turn on the channel is still below the threshold limit of secure flow velocity in open channel flow permitted ie 1,0 m/s to 3,0 m/s, flow rate on the secondary channel Batu Kumbung is 0,59 m/s, the secondary channel cottage remove 0,1 m/s, and secondary channels Pade Merce 0.2 m/s, the magnitude of the channel geometry elements tend to expand the volume of the flow channel.
