PROBLEM TO BE SOLVED: To provide structure of an ultra low head drop water turbine of a flow velocity/rate adjusting type, which can actively respond to an area where a water level, a flow rate, and a flow velocity fluctuate greatly, and in which a fixed flow rate and flow velocity are always kept to improve the efficiency and operating characteristics of water turbine, thereby to provide uniform electric power. SOLUTION: The structure of the ultra low head drop water turbine of the flow velocity/rate adjusting type is installed to an area low in water depth such as ocean, a river, and an artificial channel. The structure of the ultra low head drop water turbine of the flow velocity/rate adjusting type includes: a support part fixed and installed to the ground; a water turbine part connected to the support part and receiving transmission of kinetic energy of water to produce electric energy; and a floating member having a flow rate adjusting part connected to an upper part of the water turbine to adjust the flow velocity and flow rate of water, having water-tight structure, and selectively rotated when fluid pressure is supplied thereto.
