Accumulation of debris at inlets of highway culverts and bridge structures is a frequent cause of unsatisfactory performance and malfunction. There are various potential problems associated with debris accumulations. In general, debris accumulations can adversely impact the conveyance through a culvert or bridge structure, exacerbate the contraction and local scour at a bridge structure, increase the hydraulic loading on a bridge structure, and cause upstream flooding. Therefore, consideration of debris accumulations and the need for debris-control structures should be an essential part of the design of all drainage structures.
Structural and non-structural measures have been used effectively to prevent or reduce the size of debris accumulations at bridges and culverts. Structural measures can include features that: (a) intercept debris at or upstream of a structure inlet; (b) deflect debris near the inlet; or (c) orient the debris to facilitate passage of the debris through the structure. Non-structural measures include management of the upstream watershed and maintenance.
The target audience for this course is structural, transportation, and other civil engineers who oversee design or maintenance of culverts or bridges.
