Ultra-low-head is an unexplored classification among the sites in which hydroelectric power can be produced. This istypically owing to the low power output and the economic value of the turbines available in this segment. A turbine capable ofoperating in an ultra-low-head condition without the need of a dam to produce electricity is developed in this study. A gate structureinstalled at a shallow water channel acting as a weir generates artificial head for the turbine mounted on the gate to produce power. Theturbine and generator are designed to be compact and submersible for an efficient and silent operation. The gate angle is adjustable tooperate the turbine at varying flow rates. The turbine is designed and tested using computational fluid dynamics tools prior tomanufacturing and experimental studies. A parametric study of the runner blade parameters is conducted to obtain the most efficientblade design with minimal hydraulic losses. These parameters include the runner stagger and runner leading edge flow angles. Theselected runner design showed improved hydraulic characteristics of the turbine to operate in an ultra-low-head site with minimallosses.
