The article showed the result of investigation of the length of hydraulic jump in trapezoidal channel. In this study, the basic factors that affect the length (Lj) and roller length (Lr) of hydraulic jump were investigated by physical trapezoidal channel’s model. The experiment carried out in purpose to establish a new empirical equation for calculating the roller length (Lr) of the jump in the horizontal trapezoidal channel with the upstream flow Froude number 4.0 to 9.0 (the steady jump). The hydraulic characteristics of forced jump were measured and statistically calculated by excel software. The results of data analysis showed that the MAPE was relatively small (< 5%), and R2 > 0.9 (strong correlation between predicted and observed values) and other statistical indicators are less than 0.1 (MSE = 0.004, RMSE = 0.062 và MEA = 0.047). Therefore, the equation found could be appropriated and applied to calculate characteristics of hydraulic jump trapezoidal channel.
