Abstract
Hydraulic capacities of commonly used sewer inlets, ditch inlets, and bridge deck drains are not well known and this seriously impedes attempts to rationalize the design of road and bridge deck drainage systems. In this report, hydraulic capacities are given for a number of sewer inlets, ditch inlets, and bridge deck drains. For all these structures, hydraulic capacity curves were developed through full-scale laboratory testing under a wide range of design conditions. The susceptibility of ditch inlets and bridge deck drains to clogging by floating debris was also studied in the laboratory. Using the experimental sewer inlet capacities, a new design procedure for inlet spacing was developed and demonstrated in two examples. Experimental drain capacities were used in the development of a new design procedure for bridge deck drainage. This procedure can be applied in an expedient computerized version. (Author/TRRL)
