Description
Bottomless (or three-sided) culverts use the natural channel bed and are
environmentally attractive alternatives to traditional closed culverts. Moreover, they are often
promoted as alternatives for replacing short bridges. These structures are typically founded
(supported) on spread footings, and the issue of scour and the depth of footing must be
addressed as part of their design. Many State highway agencies will not allow bottomless
culverts unless they can be founded on solid rock formations. Therefore, there is a need to
formulate a defendable procedure for estimating scour depths in other types of soil formations
(e.g., sands). The scour problem is analogous to abutment and contraction scour in a bridge
opening and can be treated in much the same manner.
