A series of 1659 tests were performed measuring the conveyance of twelve (12) different catch basin inlet configurations for various road orientations. The catch inlet combinations include single and double round herringbone grates (OPSD 400.070 and DWG. No. S19), 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), circular closed cover (type A) (OPSD 401.010) and single and double curb mounted inlets (DWG. No. S22 and DWG. No. S28). These tests resulted in 116 catch basin inlet rating curves which are presented in this document. The experiments were performed using a full scale model roadway at the Ocean, Coastal and River Engineering Research Centre of the National Research Council Canada in Ottawa. Water flows ranging from 0.001 - 0.41 m³/s were delivered to the model roadway and six (6) road grades ranging from 0.5 - 10.0% and cross-slopes of 0.0, 2.0 and 4.0% were examined. In this document the experimental setup and methodology are reviewed. The 116 best fit catch basin inlet ratings curves are provided. The experimental data on which the rating curves are based along with the uncertainty analyses are provided. An example of the analysis to obtain the best fit ratings curves from the experimental data is reviewed.
This work provides the best fit curves to the experimental data obtained in the following two reports: "Experimental testing of catch basin rating curves" & "City of Ottawa catch basin performance study"
