What is it about?
We optimized geometrical dimensions (length, width, sagitta, and angle ) of the plain jet-breaker which was suggested by Granata et al. (2014) for drop manhole. Manhole Laboratory model was studied and experiments were designed by the modern statistical design of experiment (DoE) methodology. Then the obtained results were statistically analyzed and proper dimensions of the jet-breaker were suggested.

Why is it important?
I believe that our work is one of the pioneers' works which bring the powerful DoE methodology into the hydraulic and hydraulic structures filed of study. This advantageous methodology results in time- and cost-effective experimentation and causes unbiased and straightforward conclusion. Moreover, matrix dimensional analysis and its results could be used in similar studies.
Perspectives
I think this research could be beneficial in drop manhole hydraulic modeling, experiment design, and data analyzing.
