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 reducing drop manhole pool height by modern statistical design of Experiment (DoE) methodology. Manhole Laboratory model was studied and experiments were Designed according to the partial factorial design. Then the obtained results were statistically analyzed and proper dimensions of the jet-breaker were suggested.

Why is it important?
I believe that this 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
This research could be beneficial in drop manhole hydraulic modelling, matrix dimensional analysis, experiment design, and data analyzing.
