| Abstract | A series of 1140 tests were performed measuring the conveyance of eight (8) different catch basin grate or grate configurations for various road orientations. The catch basin grate combinations include single and double round herringbone grates (OPSD 400.070), single and double square herringbone grates (OPSD 400.020), square grate with square bars (MT-310), high capacity inlet (Stepcon 5103), circular open cover (type B) (OPSD 401.010) and circular closed cover (type A) (OPSD 401.010).
These tests resulted in 80 catch basin rating curves which are presented in this document. The experiments were performed using a full scale model roadway at the Ocean, Coastal & River Engineering Research Centre of the National Research Council Canada in Ottawa. Water flows ranging from 0.001 - 0.40 m3/s were delivered to the model roadway and six (6) road grades ranging from 0.5 - 10.0% and cross-slopes of 2.0 and 4.0% were examined.
In this document the experimental setup and methodology are reviewed. The 80 best fit catch basin ratings curves are provided. The experimental data on which the rating curves are based along with the uncertainty analyses are provided. Examples of the analysis to obtain the best fit ratings curves from the experimental data are also provided. |
