Abstract
This report provides catch basin inflows for four catch basin inlet configurations at four grades ranging from 0.5 - 5.0% and cross-slopes of 0.0, 2.0 and 4.0%. The curves relating the incident water depth to the catch basin inflows were developed from a series of tests with a mock-up of a roadway conducted at the Ocean, Coastal and River Engineering Research Centre of the National Research Council of Canada in Ottawa. Water flows ranging from 0.001 - 0.41 m³/s were delivered to a model roadway to quantify the conveyance of the catch basin inlets for various roadway grades and cross-slopes. The report covers a review of the model roadway used and the experimental setup. A review of the instrumentation used and the measurements performed in this work follows. The four catch basin inlet combinations used in the study were examined. A preliminary analysis including an assessment of experimental uncertainties was performed. The detailed results from each of the four catch basin inlet combinations were provided. Finally, a comparison of the performance of the four catch basin inlets covered in this report is performed.
