A new type of cross-flow turbine that is suitable for an overfall sill in the irrigation channel was developed. If the head of the turbine is very low, a draft tube is needed to effectively utilize the height difference between the runner and the water level in downstream channel as the hydraulic head. Therefore, predicting the performance of a cross-flow turbine is more difficult than that of other turbines with single-phase water flows because pressure in the runner chamber also influence the performance of the turbine. In this study, a performance prediction method for a cross-flow turbine with a very low head is developed by experimentally investigating the influence of parameters such as pressure and net head on the turbine performance.
