Web1. Span1 streams or size culverts or pipe arches such that they are wider than bankfull width (BFW). Spans are strongly preferred as they avoid or minimize disruption to the streambed, and avoid entire streambed reconstruction and maintenance inside the culvert or pipe arch (see 4, 5 & 7 below), which may be difficult in smaller structures. Webculvert, such as a round pipe, pipe arch, structural arch, or box, depends on the site, the needed span, and the allowable height of soil cover. The key factors in culvert selection are that the culvert has adequate flow capacity, fits the site, and that the installation is cost-effective.
