This article presents the results of theoretical studies of the undershot water wheel that works effectively in low-pressure watercourses with a water flow speed of 1-4 m/s. When developing a mathematical model of the undershot water wheel, the Matlab/Simulink program was used. According to the results of the study, it was found that for the efficient operation of the undershot water wheel in low-pressure watercourses, the angle of inclination of the blade at the exit from the water is β=30°. Also, during the study, the water flow rate and the efficiency of the undershot water wheel were determined.
