Hydraulic Characteristics of Flush Depressed Curb Inlets and Bridge Deck Drains
The report presents the results of a research project to determine the hydraulic characteristics of and to develop design equations for two types of stormwater drainage structures: flush depressed curb inlets and bridge deck drains. Flush depressed curb inlets are so named because the lip of the inlet opening is flush with the curb line and the gutter section adjacent to the inlet opening is depressed. Bridge deck drains consist of grated openings in the bridge deck supported by a drain pan. All of the drainage structure designs tested in this project are used by the Texas Department of Transportation in the State of Texas. Except for one of the bridge deck drains, no empirical design information existed previously for any of the drainage structures tested in this project. One of the bridge design information existed previously for any of the drainage structures tested in this project. One of the bridge deck drains had been tested previously in a different orientation. To determine the hydraulic characteristics of the drainage structures, models of the structures were tested on a large roadway model. Curb inlets were tested at 3/4 scale; bridge deck drains were tested at full scale. The measurements made during the model studies were correlated to the capacity of the inlets and drains to develop empirical design equations. Two types of bridge deck drains were tested. Empirical design equations were developed for both drains. The equations are a function of the roadways geometry and approach flow conditions.
