Webbdescribed and tested for a multi-gate sluice structure regulating discharge from a river to the sea. The number of opened gates is varied and the discharge is stabilized with automated control by varying gate openings. The free-surface model was validated for discharge showing a correlation coefficient of 0.994 compared to experimental data. WebbThe values of coefficients of contraction (C c) and discharge (C d) increases when gate slope increases with flow direction and the lower lip is horizontal, these increases are (16)% and (18)% respectively, while these values decreases when gate slope increases opposite flow direction and the lower lip is horizontal these decreases are (13)% and …
