Abstract: 
The model design was developed for the alignment and it was utilized to test for various geometrics and stream conditions searching for a low and incentive for RMSE and the response variable. Also, during the alignment half of the exploratory information was set to their coefficients, and the staying set of information was similarly be utilized for confirmation purposes. Utilizing around thirty out of the fifty informational collections created in the research facility dependent on relapse investigation was applied to the non-direct model to decide the constants. The staying twenty informational collections from research centre analyses were utilized for check of the model. The absence of the fittest was utilized likewise to check the request for the proposed relapse model utilizing the water profundity as the response variable. The Froude numbers from the post-pressure driven hop segment from 0.37 to 0.41 (0.37 < Fr3< 0.41), likewise showing that the streams are subcritical. The Froude numbers from the post-pressure driven hop area inside 0.37 to 0.41 (0.37<Fr3 <0.41), this shows the streams are subcritical. The connection between sequent profundity proportion y3//y2 and speed proportion V2/V3 is around - 5024 +1.485 Fr2 with R2 =0.9957 showing that as the sequent profundity proportion and speed proportion expands the inflow Froude number Fr2 additionally increments, the hydraulic jump extended from - 0.001 to 0.001 which gives some vitality progression with an expansion in the pace of release through the flume. The upstream of the flume, the Froude numbers go from 0.038 to 0.052 (0.038 < Fr1 < 0.52), demonstrating that the streams were subcritical and less harm to the channel.
